transmission

Hey, im looking to buy an 08 2500HD silverado, i found one for a good price but it needs a transmission. The current transmission is a automatic but i was wondering if it would be possible to manual swap it if i bought it. i dont know if chevy even offered a manual in 08 but i thought about...

So I’ve been having this issues for over a year now. Last year a trans fluid line blew and made The tranny slip with no fluid in it, good thing it happened a block from my house. After I fixed it up and re filled it she worked fine for few weeks then it started to get stuck into gear i believe...

Hey guys, looking for some advice on my truck. It is a 06 duramax lbz all stock with the allison automatic 186k miles. Yesterday driving my truck home from work I noticed my truck was shifting later than usual, and at some speeds(right around 32-45) didn't want to shift up into the higher gear...

I just did a fluid, internal filter, external spin on filter, and pan gasket change. When I finished I looked at the old internal filter and realized there was no seal on it, which means it separated and stuck in the hole and I just jammed the new filter with its gasket into the old gasket. I’ve...

I was leaving Taco Bell on Friday, and when I shifted from park to drive, there was a delay, clunk, then immediately “GEAR 4” is displayed on my monitor. I pulled over and ran codes, and saw TCM. I tried clearing them and shut the truck off. Started back up, drove maybe 2ft and then clunk! 4th...

Hello everyone, i was driving home this morning from work, and i was going up a decently steep hill. i was accelerating pretty hard before i heard a noise and then my truck kinda jerked a little, then my rpms dropped, then started increasing but my transmission wasn’t shifting right away, then i...

I recently bought an 05 LLY with 250k, owned for about two weeks and I noticed puddles of dexron near the driver side front tire. The strangest part is that it’s not an everyday occurrence. Some days it leaks, some days it doesn’t. Sometimes it’s a decent sized puddle, sometimes it’s a few...

Had this 02 since it was new. It’s got 96,000 miles on it. Mostly pulling hard with hay out of the hay field . Got hot while pulling a 30’ flatbed with 70 hp tractor on it on the highway . Was jerking and it was stuck in high gear . Didn’t check tranny temp . Mechanic reset it and changed...

Codes pulled via CTS2: P0088 P0089 P0700 U0106 P0307 P0463 P1093 2004 LLY. Truck doesn’t have a past with me unfortunately. Bought at auction. Truck displays service 4 wheel drive, and water in fuel. Only thing I’m concerned with is the trans right now. Truck goes into drive and reverse very...

2014 chevy silverado 3500 HD 6.6L Duramax / 6 speed Allison... While getting some brake work done, I was thinking of having the transmission flushed. But the mechanic told me that if it's never been done before, I could have a blown transmission within a week. I guess a flush would clean all...

Ok, 2003 GMC D/A...on the dash it shows D 3 2 1, but I have counted the shifts many times now and it shifts 5 times. The last shift is at about 55mph and 2k rpms. Also 2nd and 3rd are really close. Is it possible someone has swapped it? How can I tell? Thanks in advance

I need help. My 2001 2500 HD has this weird problem and is getting worse. When I stop at a light and 15 seconds later it feels like someone drove into my back bumper,a really strong loud clunk. Also when I roll through a turn and I step on the gas its like in neutral and when the revs come down...

so i roll from about 60-70k, brake, come to a complete stop at a red light. sit there for a few minutes, go to go over the overpass and onto the offramp. Truck wont move when i let off the brakes. give it gas, finally starts to move probably around 1200-2000rpm? i assume it is ice on the...

So I have a feeling that my tranny is about to take a dirt nap. Which isn't that cool but it has been throwing some p0700 p0840 p0746 codes and its done that twice as of late. It started leaking fluid, i got that to stop now i can smell tranny fluid when i get out of the truck. Hasnt thrown any...

New Here, Thanks to all of you who contribute to this site. It helped me fire up the truck I bought. Now I have a new problem and after running a quick search, I couldn't find anything relevant to my situation. The truck was running fine until I noticed it getting sluggish. The RPMs started...
