Hey guys this is my first time posting on the forums, recently bought a 2003 gmc 2500 6.0 gas. 4x4
So last owner got stuck in his driveway and had bypassed the mechanism by breaking the tumbler & started the truck via the ignition switch (already checked if it was stolen lol). i think he played with a few wires to bypass the security as well, but im not to sure on wiring.
So to the point i had to drill out the old cylinder and play with it cause it was jammed and could not set it to the ignition setting to pull the old one, during this process i noticed a cable came loose that connects to the cylinder housing and would move with the key when you go from power to start it, pulled it out by accident & then truck was locked in the park position after i put the cable back i was able to shift but noticed it shifting freely afterwards. Already put a new tumbler in but still can shift with no brake, even with the truck off. I can still pull that cable out and the truck will lock into park but when i put it back it shifts free again.
I just took the truck in for an out of province inspection(canada), and that was not an issue at the time so im 95% sure i did something to cause this. but could also have not noticed it as its second nature to put your foot on the brake then shift. but doubt it as it was just inspected yesterday
Any help is appreciated and i can also post pictures when i make it out to the shop. Thanks!! ( Just remembered as well, disconnected the battery prior to working on the tumbler. because i was checking horn wires under the airbag, as the horn does not work not sure if disconnecting&reconnecting the battery can affect shifting in anyway)
I have a 2012 GMC Sierra 1500 Z71 4x4 SLT. Latley I have had an issues with the shifting. Most of the time all is good, but when I'm going between 35 and 40 and let off the gas then give it some gas it hits real hard. It does the some what of the same when I am on the highway going about 70 and I give it more gas. On the highway it seems to down shift ( feels like I'm stopping) than shifts hard. The transmission was just rebuilt and I just replaced the tps and cleaned the throttle body. I at a loss and am running out of money to throw at it. The transmission shop ensures me it is not the shift soleniods, he says if it was I would have a lot more shifting issues than I currently have. Also, the check engine light does not come on and there are no codes in the history. Any help would be appreciated
I recently inherited a 2002 Silverado 1500 Standard cab 4.8L 4x4 manual NV3500 transmission. It has 208k miles on it. My oldest son is 14 and we plan to restore it so he'll have something to drive when he gets his license. It drives very nicely. There's some slop in the front end and I expect it's due a pitman and idler arm, ball joints, and probably tie rod ends. Aside from that, the only thing that concerns me is shifting from 2nd to 3rd. It's really hard to find 3rd gear, and when I do it takes a little force to get it in there. Downshifting from 4th to 3rd is smooth. Any ideas as to the cause and fix?
So I tried to drive in the manual mode, with the 1,2,3 gears after the Drive position, and once I got up to around 25mph, it shifted by itself (I’m guessing to 2nd gear) but I didn’t even shift my shifting column to 2nd, and it still showed the truck being on 1st gear on the cluster, can someone help, I have 2005 Silverado LS crew cab 5.3L
I have a 2016 Silverado Custom double cab and I was wondering if anyone has this particular issue that I have been dealing with for quite some time. I purchased the truck brand new from my local dealership and as time went by it developed this clattering noise. This particular noise tends to appear when I am either braking while entering an intersection or driving and slow breaking. It sounds like its coming from the middle compartment of the truck and I cant seem to figure out what the deal with it is. I have tried with no success to record the noise in order to take it to the dealership to no avail. I have taken it to the dealership but they tell me that I have to replicate the sound in order for them to be able to determine a diagnostic in order to fix it. I took the tech on a drive but I was unable to duplicate the sounds. It sounds like its a progressive clanking noise of two metal pieces. The sound is not constant but rather it tends to build up in noise and then clutters down. The truck has only 11k miles on it and all have been placed by me. If anyone can please help me with this so that I can take it to the dealership with something in order for them to handle this it would be greatly appreciated. Thanks.
