Just bought my first GMC a week ago. It is a 2016 with 55,000 miles 5.3 SLT 4x4 with Z71. I looked the car over pretty good but noticed something after we got home. Is this the common leaking crimps I have been learning about on these vehicles with transmission lines? I have to crawl under the vehicle this weekend but this was the picture I was able to get. The gunk had no smell to it at all.
And not sure if the Rancho shocks are completely shot on this Z71 package but on the highway and my first speed bump the words....Old Cadillac came to mind about how much it wallows. Thanks everybody for your time....
I purchased a 2014 gmc 5.3 with 80k. the lifters were all replaced under warranty. soon after i noticed 10 psi oil pressure after driving 25 min on highway. dealer replaced oil pump still has 10 psi after 25 min of driving. when i first start up its at 40, oil pressure goes to 70 when rpm exceeds 3500 rpm. oil pressure starts to drop to 20 after 10 min and seems fine. after 25 min it drops to 10 on guage. i had oil pressure checked with mechanical guage and confermed guage is accurate. i asked dealer to che k the screen under oil pressure switch they said it was clean. at this time dealer says nothing is wrong due to specs at 1000,2000,3000 rpm. i called gm customer care and they said to get different dealer to look at. i did and they confermed rpm at different rpm and charged me 118.00 gm customer care did nothing to help me out. i have never seen any truck with 10 psi at idle. does anyone else seem to have this issue?
I recently did a dod delete on my 2007 suburban. 6.0 200,000 miles. I thought the problem was the afm lifters being that there was a tick at highway speeds. I only had a tick at highway speeds. If I drove on the street I would never get the noise. As soon as I held a steady speed on the highway I would get what sounds like a lifter tick. The dod delete work was done by a Preformance shop. I do not think that dod was the problem. If I hold the throttle steady at 2000rpm while in park I can get the tick to come on. After I let the engine idle about 2-3 minutes the tick goes away. As soon as I hold the rpms back up it will come back and repeat the process. No loss of power while this is happening and no other sounds. Oil pressure is about 10-15 at idle and close to 40 while on highway. I would greatly appreciate any help.
Good morning guys,
Obviously I'm new to the forums, so thank you in advance for your understanding! A little background on my situation -- I always make sure to maintain my vehicle to the best of my ability (both proactively and within my financial budget), but my Chevy Silverado just hit it's 75,000 mile mark with no previous transmission fluid maintenance.
2011 Chevy Silverado 1500 (Standard Work Vehicle)
Pre-Certified with 3,008 miles on it, pretty much brand-new -- Purchased in Oct, 2013
4.3 Liters V6 Engine
75,600 miles currently
The only thing it's ever towed is the smallest Uhaul for about 600/miles, and sod back in the day. For the past couple of years I've only driven it to and from work (50 miles round trip in city/highway), but for the most part this past year my new place of employment is super close, so that dwindled to around 25 miles round-trip.
I've only ever replaced the engine oil and filter regularly, and tires a year ago, so when it comes to how I should maintenance the transmission oil, that's a bit foreign to me unfortunately. I've heard if you make it passed 70k with no issues, it's not wise to flush it out entirely, but more so the 50/50 (old/new) method? I would like some advice from you tenured vets on this, and to see if I should take it to the Chevy dealer or a transmission specialist?

Hey guys looking for all the advice I can get. I have done a fair bit of research already. However, I am going to change the transmission fluid in my 2007 (New Body) Silverado. If it matters it is a 4.8 V8, 4x4, regular cab and long bed.
1.) I do not know exactly what filter kit I need. I went by Advanced Auto Parts and the guy told me you usually count the bolts on the pan but he said for this specific model there are two different ones. I called General Motors and talked to what I am guessing is a foreigner that lives in another country. I gave him my VIN and he could not tell me what I needed to know. Does anyone happen to know which one I need?
2.) My truck has 95,000 on it and to be honest he oil does not look good. When I pull the dipstick out and wipe it off it is pretty black/burnt but there is definitely still a little red to it. I was told that if it was in really bad shape not to change it because I know I can risk damage. I know this is true but not sure if it has been neglected to that point. It is sort of weird that I can still see red meaning someone might have dropped the pan at one point and added oil in. I bought the truck used.
To try and keep this short I will say I am pretty well researched from YouTube and other forums. However, any advice from people that have a similar truck to mine would be greatly appreciated. For instance, I know that I am going to have to drop the exhaust to remove the pan.
Just so you guys know I plan to remove the transmission in line to the radiator and let it pump out as much as it wants. After it stops I am going to put it back together, drop the exhaust, drop the pan, replace the filter and gasket, then put it back together. Also when I go to get a plastic hose to guide the old oil out does anyone know what size hose is a good fit for my truck? Also where can I buy it, my local auto parts store? I appreciate any help in advance.
