Replying to: renegade0351 (Jul 31, 2006 1:01 pm) Exact same jerking problem here for many months and getting worse... but with a 2006 Silverado 2500HD with less than 7,000 miles on it. 36 month warranty expired yesterday. Dealer says "screw" today after telling me they could find nothing wrong at last couple visits (of course not - problem is intermittent). How do I fix this thing???

We took our 2001 duramax to the shop in the beginning of May, and still haven't gotten it back, now its 4 months later and no one knows whats wrong with it, still! Tranny has been rebuilt 3 times, getting the run around from alaska sales (the chevy dealer up here) and no tranny shops or any shops period other than alaska sales and the original shop that rebuilt it, WILL TOUCH IT. so we're kinda out of options. Have yet to meet anyone who could give any insight on our truck. As far as I know there are a few factory recalls on the 99-02 silverado's so if yall are havin problems with one of those i'd look the recalls up and the symptoms it that part was out or going out and maybe that'll fix your problem. One of the ones that has to do with the tranny is a part in the torque converter and the Park neutral saftey switch also. check it out, maybe it'll help you.

MY 2001 CHEVY SILVERADO HD ONLY DRIVES IN GEAR 1,2,3. IT I LIKE IT IS NOT ENGAGING IN DRIVE OR REVERSE. I CAN HEAR TRANSMISSION TURNING BUT TRUCK BARELY MOVES. COULD IT BE TORQUE CONVERTER. IT WENT INTO DRIVE AND REVERSE FOR A SECOND AND HASNT DONE IT AFTER THAT. OTHER THAN THAT IT DRIVES GREAT IN GEAR 1,2,3.

Here is the scoop...Love this truck! Never had problems. At 35500 miles the tranny started upshifting hard. Parked it at night hasn't done it since. Took to dealer, can't duplicate. Few days later, the reverse doesn't engage without extra human tricks like extra gas and working shifter in and out of gear. That happened twice. Took to dealer, can't duplicate. Ok we are still under warranty (plus extended) so we will continue to drive it till it fails. All seems ok untill it is driven to Houston and back about 80 miles round trip and the tranny overheats with a message from the DIC. Took to dealer ( real jerk service manager) didn't wanna deal with it because we didn't buy it from them so with a call to GM they changed their mind. Here is the warning. They claimed it was low on fluid. Bull shit! and their computer said change fluid and filter at our expense. This is the game. You say no and they win because you didn't do as they recommended. You do it yourself they will claim you voided warranty by screwing something up. Outsmart these cocksuckers. I said ok. Go for it. Yeah it sucks out of $135 for them to use us as guesswork diagnosis guinea pigs. Picked it up and we did the test drive. Didn't even make it to Houston before it overheated. Well its back at the dealer and they are gonna tear it down. I in the mean time I will gather weapons such as the ATSG manual and a current live data OBDII scanner. I will keep yall posted on the outcome. Thanks to all that post here, you have given me a weath of knowledge to go to war with these asses!

Replying to: redbuggyboy (Sep 13, 2009 9:38 pm) Not much detail to report other than finding metal in the clutches and damage to the mechanical parts.(wish they were more specific) The dealer ordered one of the GM certified remanufactured and installed it today. We drove it home with no issues. The shifter lever is not perfectly aligned for putting it into 1st gear so I will see how hard it is to do and if it is too challenging will take it back and make them do it. The remanufactured has a 3yr 100,000 mile warranty on it and should have improvements that GM is aware are needed like a stronger sun gear I hope. If we have any problems I will be sure to post them.

#490 of 506 04 GMC 2500HD Tranny question. by svga Sep 19, 2009 (10:15 am)
Hey all....I just picked up a 2004 GMC 2500HD 6L 4x4 a few days ago. I test drove it twice before I bought it. Here is my question.   Should the tranny make a slight "honking" (cant describe it any other way) sound when taking off from a stop? It doesn't happen all the time and I never heard it when I test drove it. I have not towed anything as of yet.   I also need to know what transmission is in it.   Thanks!

#491 of 506 Clunk upon acceleration by joopdog Sep 25, 2009 (7:44 pm)
I have the following: 1996 Chevy Pickup truck V6 4.3L engine   When I accelerate from 1st to 2nd gear (10-15 mph) I get this noticeable clunk noise. It all started on Monday (09-21-2009), it just started out of the blue. No gradual noises, no warnings.   I believe it's coming from the transmission. And now, it's beginning to leak. I see wet spots under my truck that I've never seen before.   What is this? Do I need a new transmission? I hope not, I don't have the expense for this.   Any help would be appreicated.

Replying to: redbuggyboy (Sep 15, 2009 8:46 pm) Ok I was gonna be nice by not mentioning the dealer we took the truck in to have the tranny problem repaired but now I am pissed. First off after we got it back I did the inspection at home and they left the vent lines all loose and didn't put the wiring back into the retainers properly. The morons left the shift cable sitting on top the transfer case drive shaft as well. This is Don Davis out of Lake Jackson, Texas....incompetent and arrogant worthless dealer and technicians. I am posting this because just yesterday the tranny blew the front seal and bled everywhere and unfortunately we have to take it back to the pieces of shit that installed the rem tranny. I spent four hours cleaning up tranny fluid from the underside and all along the passenger side of the truck! So much for having a oil free truck!!!!! I will post on what takes place. Thanks Don!!!!!!!!!!!!!!!
