  1. Can any one help me find this issue. On my 08 Silverado 1500 Vortec Max I can drive normally find no issues no lights etc. Sometimes though I can either be going over a small bump going around 10-20 mph and then it clunks and then goes into neutral. The 2 other ways it happens is when I make a turn and give it some gas to speed up it revs up and clunks and then goes into neutral and the 3rd way can be in 1st gear and then putting a decent amount of gas on it and then it does it again. It acts like its in neutral when its in drive and if I stop it just makes a bunch of noise and I can step on the gas and no movement.It sometimes will just go back into drive but other times I have to put it in reverse wait a second until it clunks back into drive and then its perfectly fine like nothing happened. The problem doesn't occur often but when it does it happens a few times more that day. I was thinking it might be a solenoid.
  2. Who else is having a transmission issue? I saw the thread about hard shift into 2nd, but towing yesterday at 65 mph the transmission literally jolted the truck like it fell out on the freeway, scared the sh*t out of me. Also under acceleration it feels at times like it cant find the right gear, hesitates a bit then finds it. Also when decelerating, letting off the gas it paused then hits. Wanted to see if anyone else is having similar issues. Ive taken it twice to my local dealership and both times they say "Sorry, we couldnt get it to replicate for us, here are your keys."
  3. Does anyone have a easy way they used to change the filter/ fluid in this trans? Exhaust pipe is keeping the pan from coming completely out.
  4. Hello there! My 1993 Silverado K1500 is throwing code 59. From what I can find this indicates that the transmission fluid sensor circuit voltage is high, which would mean that the sensor is telling the computer that the fluid is too hot? If I clear the codes and start the truck cold, it immediately throws this code. So I know **for sure** that the transmission isn’t actually hot. My question is, how should I go about diagnosing this? Is the sensor external and is there a way I can test to be sure the wiring is right? Or is it internal and should just be replaced? Appreciate any pointers you can give me.
  5. Sorry if this seems long winded but I want to provide as much info as possible. Just picked up a 2019 Silverado 1500 custom. Has the 4.3 V6 with the 6 speed transmission (6L80 I believe) The truck had 99 miles on it. Currently around 2500. No issues out of the gate, after about a week of driving I noticed a very delayed shift I think it was from 1-2 or 2-3. The engine revved 1-2k high RPM than normal before shifting. a few days later while on the highway (cruise set at 75mph) out of no where the RPM’s spiked as if it had downshifted. There was no additional load on the engine to cause this, like going up or down a hill. This happened a few times. I called the dealership immediately and brought the truck to them a few hours later. Got a loaner for a few days while they looked over it. They called me to come pick it up, said the tech noticed a little bit of rough shifting and said they “re-set” the shifting points. Since it was an intermittent problem for me I don’t think it arose for them. So I took the truck home, no problems. My wife drove it to work that same night and the same problem happened again. This time the engine light came on. I scanned the codes this morning and the ECM showed P0700 (transmission control system the TCM showed P2714 pressure control solenoid D performance/stuck off. So back to the dealer it goes, waiting for them to bring me a loaner this time. I was was told by a dealer technician that GM has been having them put a different type of transmission fluid in some of these trucks due to issues with the torque converter. But I guess if a solenoid is stuck it could be due to a fluid issue as well? Just speculating. I’m curious if anyone else has had similar issues. I haven’t had much luck finding anyone else online with the same problem. Which is guess is more of the reason I’m posting this, in case there’s someone else lost like myself. I will keep this updated when I get further down the road with the dealership. I get that there are fluke problems that can arise, but this is a bit irritating considering it’s a brand new vehicle. I will say that the dealership I’m working with has been extremely supportive and not trying down play anything I’m complaining about.
  6. Hello! Just joined because I'm looking for directions. My '98 Sonoma runs like a dream...except, there is a slight delay in the engagement when I shift into reverse. Not sure where to begin in my search for information and options. I'm in the Greater Detroit area. I've kept the truck well maintained despite the 264,000 miles. Original engine and transmission. Where can I look/who can I talk to/what do I ask? Thanks! and I wish I found this site sooner. Pat
  7. Anyone have a check engine light show up then go away and come back? Code uo129 lost communication with brake control module, UO101 lost communication with transmission Control Module. Went to bed with no check engine light, woke up in the morning for work and noticed the truck would not remote start. When I go in to head to work noticed check engine light. After work ran codes. Shortly after getting codes and using google to research check engine light was gone. Went for a drive never came back on. Woke up this morning it was on again. Can anybody relate?
  8. Anybody help me out in figuring why my transmission shudders at low to no speed while in gear and even sometimes when it is not in gear. Possibly be low trans fluid? 73,000 miles on it and far as I know it hasn’t had the transmission serviced. I've read about problems with transmission shudder on the 8 speeds but this is a 6 speed. Do they have the same issue?
  9. So, not sure if I'm the only one who has this issue at 130,061 miles but for some reason one night my truck was shifting pretty harsh, keep in mind this is the first time it's done this. I was far from home so I just drove home because I didn't have the money to have it towed nor was I going to leave it out here for looters to break into. Drove it home and just down the street from my house the truck just did not want to drive. It wouldn't go into Drive or Reverse, had to push her heavy ass home. Next day I decided to see if she'll budge and long behold it actually went into gear and I was able to move it where I usually park it. I did not take it for a drive afraid it would happen again. Anyone know what could've caused it to just stop going into gear and then now it will. Seems odd to me.
  10. John Goreham Contributing Writer, GM-Trucks.com 4-25-2019 Back in December, GM-Trucks.com member Jammin87SS posted a note here about a class-action suit related to GM 8-speed automatic transmissions. This transmission was used widely by GM, including in the Sierra, Silverado, Colorado, and Canyon pickup trucks. Owners have been complaining of shuddering and hesitation. Owner of a Silverado, Ed T., wrote a typical description for CarComplaints. He says, "Ever since I bought this truck new there has always been a shifting problem. This problem occurs whenever I slow down to a fairly low speed and then accelerate. When I accelerate there is a hesitation for a second or 2. This is very annoying and could potentially be dangerous. I have contacted my dealer and he just says "that's the way they shift, no fix"??? Dealer also stated that the transmissions have a learning chip and shifts the way a person normally drives - that's total BS. I have had my truck for over 2 years and it still shifts poorly. Besides the above I love my truck very much, GM just has to fix this problem..." GM knows there is a problem. It has issued both notices to its dealer's technicians and also TSBs. However, it has yet to find a solution that works. There is a class action suit that you can learn more about here. Our questions for our members are; 1) Have you experienced any issues with your 8-speed, and 2) was the dealer able to fix it? Let us know in the comments below.
  11. I waited several extra months for the AT4's release to purchase my truck. Less than 1 day of light driving and 70 miles into my new truck the transmission started to slip in and out of gear. I pulled into a parking lot and when I shifted into revers the truck slowly rolled forward. Onstar had a flat bed tow truck there within an hour to bring the day old truck back to the dealer. The dealer can not start work on the truck until GM approves the new transmission. I am told that there is a lot of extra paperwork and approval because there are so few miles and it is a new truck. I would think that GM would want to maintain their customer loyalty and support their new designs before aggravating buyers of new trucks. I have been a lifelong GM buyer, but thinking that i should have gone with a Ford or Ram. Has anyone else had to wait for repairs on a brand new vehicle?
  12. Hello everyone, Well I took my 2014 Chevy Silverado 1500 up to the dealership yesterday for transmission issues. When accelerating around 30mph the transmission makes a high whining noise around 2000 rpm almost like its slipping and the truck shakes back and forth. Then when on the interstate on cruise control around 65-70 you will hear a grinding noise every few minutes. Also when you slow down from the 60-70 mph range to around 30 mph and accelerate the grinding noise becomes more apparent. When I dropped the truck off yesterday I showed the service guy video of the grinding as well as what I believe to be slipping and he said "Yeah that sounds like it is slipping". Received a phone call this morning from the same service technician saying they were not able to replicate the issue. That the transmission guy said that is normal when it switched between V4 and V8 mode. It's amazing I have had this truck and driven it for 76000 plus miles and have never heard that whining or grind noise. I asked how long they test drove it and he said 10 minutes. I told him they need to drive it around longer and actually go on the interstate to hear and see what it is doing. This is not the first time I've taken my truck up there for transmission problems and I am not picking this truck up again until they find the issue. The first time was for rough shifting to which they said was normal. This is my first Chevy I ever have bought or owned. Bought it brand new from the dealer. I must say that with how I keep getting treated with the "can not replicate" issue as a scapegoat for not truly trying to satisfy the customer is getting old. Especially being I have videos in which you can see the rpms and hear the whine up and hear a grind noise. This will most likely be the last Chevy product I purchase. If anyone has any ideas and doesn't mind listening to the videos I have I would appreciate it. I will have to post a link to youtube since the video will be to big to post here. Thanks
  13. 2015 sierra denali 5.3l trans failed at 100,400 miles was flushed at 75k I had bought 100k extended warranty that ran out 300 miles ago. I am hoping GMPP does the right thing here. Also I was notified the week previous that my magnaride struts are leaking and wont warranty them. Seems ridiculous to me these thing all failed at 100k
  14. Rpm go up and down while driving steady near 55 to 65 fell vibration while shifting up and down
  15. Hello, Has anyone else experienced any shifting issues on their 2019's? The big one I seem to get a hard shift point around 2-4k RPM coming off a stop under light gradual acceleration shifting from 1st to 2nd gear. It's fairly random but seems to be more common after the transmission heats up 150-160 degrees or more, though it'll happen cooler too. The other is when feathering the throttle in traffic the downshifting seems a little harder than it should be, not as hard as the upshift and it doesn't clunk like my old 16' but it's a feeling like driving over a small bump occasionally but it's happened enough while watching the RPM needle shift to think it's not just the coincidence of running over a little bump. Typically during low traffic speeds < 30mph. All in all, the transmission is a vast improvement and is way smother compared to my clunky 2016 5.3L 6 speed Z71 which I traded in with 35k miles after valve sticking issues and a transmission rebuild replaced a fair bit of the transmission (torque converter, valve body, transmission pump). I cant tell if i'm just sensitive to the transmission or if I have something worth pursuing, service department says to give it 1500/2000 miles while the truck is "learning" as mentioned in other threads, I currently have just shy of 1100. After that I dread the "normal behavior" discussion. Overall it's a great truck, really smooth overall and a beast on the open road, in fact it's so smooth most of the time I think it might make the slow speed hiccups seem worse than they are. It's just a concern knowing that if it starts shifting issues at 500 miles, what's it gonna be doing at 20k miles etc.. Thanks everyone for reading! What's your experience? 2019 Silverado 5.3 V8, 4x4, Z71, RST
  16. I recently acquired a 1951 Chevrolet 6100 missing its engine and would like to refurbish it. However, Instead of putting in the original engine (Chevrolet 235) I am looking for an engine that came out in the next 10-15 years to put in my truck that will out put 200+ horsepower without being out of touch with the truck. Any advice would be greatly appreciated.
  17. Hello T1XX owners, Did anyone put a dipstick in there 8L90e transmission yet? I would like to get a dipstick but am not excited about spending $180 and putting three holes in my new truck. B&M makes one that works but $180 seems like a lot(also three holes). Has anyone taken one from a Camaro and put it in? They have the same trans but different motor. so it might fit the trans but the bolt location might be different. My question again is, has anyone did it yet? What did you buy? How do you like it?
  18. Hey guys, new to this forum. Recently purchased one of the dream trucks of mine, 2014 Sierra Z71 4x4 5.3l. Which I was finally able to afford lol, bought from a local dealer with 88k miles. Prior to purchasing I test drove it, checked the history and maintenance records from GMC. All seemed well, purchased it and few days later while driving home on the highway cruising about 60-70mph, I began noticing a really loud sudden vibration that would come and go every few minutes (feels like it’s coming from underneath the truck not sure), lasting about 5 seconds. Even around 20-30mph I notice some shaking. Seems to be shifting fine, drives pretty smooth other than these vibrations that are coming and going. I just don’t know what it could be. I didn’t notice it during the test drive, just my luck, hoping for the best. Any opinions are greatly appreciated, I attached a video as well of the sound. 85CD798D-6EDF-4AD3-896A-02B1F45F48D7.MOV
  19. Question to all new truck buyers who bought a 2018 Chevy Colorado, you having any transmission issues, like slipping between 2nd and 3rd gear on the automatic floor shiftier or problems with the + and - buttons ?
  20. 2015 Chevy Suburban with 130k, transmission went just like everyone else's, so I had it rebuilt at a outside shop with a trusted mechanic but I keep on having to bring it back. He rebuilt it and it took a week for the converter and the new gears to shift smoothly once again (normal). But now Im having problems with the temperature. My transmission temp is skyrocketing to 260 degrees with no check engine light coming on. After doing further investagation and taking the dipstick out and looking at the fluid and touching the stick it wasn't burnt or hot at all. The stick was cold. This is causing both my fans to blow cold air which is doing nothing and the temperature stays. The engine temperature is normal around 190. I love these trucks but with the amount of money put into them to keep is insane.
  21. My 2006 Chevy Silverado 1500 Z71 won't shift into overdrive. -It started with, my check engine light came on Blinking the other day but then the light shut off almost immediately. I had pulled over, once the check engine light shut off moments later I went to pull back out and the truck wouldn't shift into overdrive. The light has come on a couple of times before but it was never blinking and usually a couple days later it would just shut of on it's own before we could get it looked at. Does anyone have any Ideas as to what might be going on? - And please tell me it's a cheap fix, HAHAHA
  22. Hey everyone, I'm having trouble with my trans. 4l60e .. Out of the blue one day it would engage after start up for about 3 mins. Then it would completely fail .. No movement in any gear... Turn it off for a 5 min crank and it repeated.. fixed that problem... Filter and seal was bad and not allowing it to seal off and couldn't transfer enough fluid... After it was fixed it worked fine.. i had to use 4wd a week later and manually sifted to 1st and there was nothing it just reved no movement or noises .. Tried 2nd -3rd same results.. it works fine in drive pulls hard no strange noises or funny feelings..shifts through all gears fine .. Any idea why it won't engage manually? Thanks-B
  23. Hey all, 2017 Silverado, 5.3/6spd. My transmission issue only happens when I first drive the truck for the first time in the morning. The truck has to have been sitting overnight for this to occur. After starting the truck and driving, the trans will "fish bite" or stutter when shifting from third to fourth. It will do this once, (maybe twice) and be good and problem free for the rest of the day. Has anyone else experienced this? It only happens when the truck is first driven after sitting overnight. It's not really a major issue, as it doesn't happen again after the first time, but it's pretty annoying. This issue only occurs at light/part throttle, and my speed is around 25-30 mph. I do not notice any variances on the tach while this happens. Also, if I drive with more pedal/throttle, I will not experience this stutter. I spoke with the dealer about this when I went in for my second free oil change, and they could not replicate the issue. During my first trip to the dealer, they downloaded a program update for the transmission. It helped overall, but the isolated problem is still present in the morning. I have read somewhere on this forum, that this was a "normal" occurance, and attempts to remedy should not be attempted. I believe that post mentioned that transmission fluid temperature played some part in this. Any ideas or input? Thanks in advance! Steve
  24. Just curious if anyone has the same issue I've been having. So on the very first shift of the day from 3-4 my trans seems to slip into gear. After the initial run through the gears it shifts great every single time after that. I have real basic stuff done to my 14 Sierra..cold air intake, cat back exhaust and blackbear tune (yes the trans was tuned). It really seems to be temperature related because it gradually got worse the colder the nights get (I live in the northeast). And no matter how long I let the truck warm up before I drive it, it does the slip but only 1 time. Not sure if this is also related but the tuner said the torque converter locks after the shift into 4th gear.
  25. Hi, New Sierra with 9500 miles. Transmission has never been right, at first service complained that it lurches at low speed, such as parking in a parking lot and feeling like I've hit the concrete stop. Also noticed that when approaching a stop light, at 2-3 mph before stopping the truck will lurch. Dealer assured that they needed to change some 'codes' in the transmission. Now the transmission slips when it's cold. Upon starting, the first application of the gas pedal after a shift into gear (whether forward or reverse) results in the engine winding up as if it's in neutral. After a second or two, the trans will "slide" into gear and the truck will start moving. Reminds me of my old Willy's when the clutch was worn out and would slip. I'm getting ready to send the truck back to the dealer - any suggestions on what to tell them or other folks that have had a similar experience? Anyone know of any service bulletins addressing this problem? thanks guys
