#3 - Automatic Transmission problem of the 2005 GMC Sierra
The vehicle's vehicle identification number (VIN) was 2GTEC13TX5_. Consumer has a 2005 GMC Sierra 1500. The truck had a transmission leak. After five times trying to correct the problem he let the vehicle go back, and lost money on the truck when he traded it in. He had the receipts available.

#4 - Automatic Transmission problem of the 2004 GMC Sierra
The vehicle involved was a 2004 GMC Sierra. There was crash involved with this problem. VIN of the vehicle was 1GTHK23154_. Our son-in-law owns a 2004 GMC 4-door pickup. It has automatic transmission. Our two-year old grandson was in the truck while his father was cleaning it. The key was in the accessory position so they could listen to the radio. The child pulled the shift lever out of park and the truck ran away down an incline. Both driver's side doors were separated from the vehicle by a tree and the truck continued until rear-ending another tree. The child stayed in the vehicle and was unhurt. In checking this truck, our 2003 tahoe, and our 2003 Chevrolet pickup we find that all of them:
1. The shift lever is locked when the key is in the locked position
2. The shift lever is locked when in the "run" or ignition position and requires the brake to be depressed prior to shifting. 3. But in the "accessory" position the shift is completely unlocked and requires only a very slight pressure to move it out of park and result in a runaway. I feel there is no reason for the shift lever not to be locked in all positions and, in fact, the fact it is locked in two positions but not the accessory position results in confusion and a false sense of security. This was not a component failure, but is a design failure that apparently involves all gm trucks and suvs of this model. This automatic transmission issue occurred 06/18/04.

#14 - Automatic Transmission problem of the 2003 GMC Sierra
I purchased my 2003 GMC Sierra z71 in Aug. 2003. In December 2003, while pulling a travel trailor, the service 4-wd light came on and the truck felt as if it had been shifted into neutral. I managed to get the truck to the side of the road and read the owners manual concerning the light. I turned the truck off as the book said and then restarted. The light stayed on, but the truck did go in gear. Since this time, when I pull the trailor for a long period of time, the truck will again feel as if it is in neutral. I have to put the truck into 2nd or 1st gear to get the transmission to engage. The 4wd light comes on with or without the trailor hooked up and has been checked several times by the dealer. They have replaced the switch but this has not corrected the problem. The transmission shifts so hard it feels as if the back end of the truck will fall out. I was told this is normal operation. Something needs to be done to correct this problem as this is a huge safety issue. No one can feel comfortable driving down a road and never knowing if you will be hit from behind due to this truck stalling for no reason. This automatic transmission issue occurred 06/11/2004.
#15 - Automatic Transmission problem of the 2003 GMC Sierra
I drive a 2003 GMC Sierra and there is a transmission problem it makes the driving very dangerous especially at highway. Speed. The vehicle cannot stay strait it either pulls to the left or to the right. The feel of the vehicle isn't right like if its dog tracking. There are clonking and ticking sounds coming from the transmission just from shifting from drive to reverse,reverse to drive. . . Park. While driving when engaging the passing gear sometimes you hear that clonking sound like if there was a slack in the transmission. I had this vehicle since July 2004 and since then I've been to the dealership a number of times everytime they said that everything was ok and showed me paperwork stating from gm canada that clonking, ticking etc. Etc. Were normal operation of the transmission. It cant be cause I had a 2001 GMC truck which I traded for, that drove like a truck this one I have now drives like a tank. Every hole or crack in the road I can feel when I hit a small hole or a dip in the pave the vehicle wants to dog track most of the time the truck pulls to the left, when it does there is a slight vibration you can feel from the accelerator or the brake. This vehicle I find is a accident waiting to happen. Its a big vehicle and to swerve side to side scares other vehicles on the highway, which puts everybody at risk everytime I'm on the road. From all these complaints I did to gm still today they tell me and show me paperwork from gm tech line. Stating that everything is normal and no work from there part should be done on this truck. It's like if gm has people working on these statements just to cover themselves from having to repair or change parts in order to save money in which I wouldn't dought. If you can help me please. Let me know cause this is a very serious matter which I would like to fix before I get into an accident. I believe there is a controversy into all of this. This issue happened on Saturday, July 17, 2004.

The car involved is a 2003 GMC Sierra. Vehicle identification number (VIN) of the vehicle is 1GTEK19TX3_. The transmission clunks when shifting from 2nd - 3 rd and at times the engine will rev and finally it will take off, this has caused an issue when going through an intersection. The dealership attempted four repairs and it is not fixed. The issue started when the vehicle had 6k miles on it and it is getting worse. The speedometer is sporadic in that it will show speed reduction/increase in segments - as if it were sticking. The erroneous speed indication causes an issue when going too slow or too fast in traffic. This problem occurred on Sun., Feb. 19, 2006.

#23 - Automatic Transmission problem of the 2001 GMC Sierra
The car is a 2001 GMC Sierra. There was crash involved with this problem. The VIN of the problem Sierra is 1GTJC33141_. The transmission violently shifts into gear upon acceleration from a stop or slow speed. This problem has occurred as many as ten times since the original date of purchase. On may 4th it occured so violently that the passenger in the rear hit his head on the rear window. In this incident the shift was so hard the rear wheels left the ground(all 4) and then the truck lurched forward. This is a serious defect that could caused harm to those inside the truck and could harm other drivers or pedestrians. The truck seems to go to a neutral operation even though you are in drive then when the rpm"s icrease to above 2,000 it suddenly shifts. I have taken the truck to the dealer 5 times and recently completed arbitration to take the truck back. The GMC represenitive claimed that this was normal for a "heavy duty" transmission such as the allison. The best discription of the problem is it feels as if you have been hit from the rear by another vehicle at 15-20 mph.

It is in the repair shop again because when you put the truck in reverse it dies. Not every time but it happens quite often. It was in the shop before for the same exact problem which resulted in 1 of the 3 new transmissions. Lets hope it doesn't need another one. This is getting old!!!!!!!!!!!. The failure date was Wednesday, February 18, 2004.

#26 - Automatic Transmission problem of the 2000 GMC Sierra
The vehicle was a 2000 GMC Sierra. On 12/13/99 when slowing down to make a left turn, the tourque converter locked up and stalled the truck in middle of traffic while crossing the left lane. With difficulty, truned the wheel back to the right and pull off the road and shifted into park and restarted the truck. Luckly there was very little on coming traffic. On 2/11/00 while coming into a rolling right hand turn and going about 15 mph, I started to brake and the tourque converted again locked up and the engine stalled. Again with difficulty I was able to steer into the corner and make the corner. As the truck was free rolling it just started itself and it contiuned on, almost crached into two cars waiting at the stop sign. If my wife was driving there would have been a collision. In October when waiting for a traffic light to change, I accellerated and truck didn't move. I stepped on the brake shifted to park and then back to drive and it finally went into gear and moved. Have been back to the dealer twice with tourque converter concerns with no solutions. Gm has a transmission problem with there 4l60e transmissions. My 1998 GMC jimmy has been replaced at 19000 miles. Am very worried that this will happen at any time when not ready and an accedent will happen. It was Monday, December 13, 1999 when this automatic transmission issue occurred.
