Silverado 2500 4WD 8-cyl

  • Automatic transmission
  • 42,000 miles


Had to replace a flexplat twice on 2003 Chevrolet 1500hd (4X4). First one at 43,000 miles, the second one was at 78,000 miles. Chevrolet would not help on either one. They also said they had no problems with it but the transmission shop found a service bulletin stating to use a new spacer if you do have problems.

- the contact has a 2003 Chevrolet Silverado with a current odometer of 60,000 miles. On 5-13-04 the brakes failed. The contact had to use the emergency brake to stop the vehicle. On 10-17-04 the transmission failed. The contact took the vehicle to the dealer, and they told the contact that the failure was due to the vehicle hauling items, but the vehicle did not have a hitch to haul anything.

We all need to contact GM at and complain. I purchased my 2003 Chevy 2500 hd in Nov. 2005. It had 32000 miles on it. The warranty ran out at 36000 and when I hit 38000 miles the problems started. The electrical system started acting up. I had went to leave and everything was dead no power at all. I would jump it and then it was fine for the first couple of times. The last time I jumped it, it cranked but I had no power it wouldn't move in drive or reverse and all the gauges went crazy. I disconnected the battery waited a minute and reconnected it and everything was working fine again. A week later the speed odometer went crazy and wouldn't go back to zero. Now starting a few weeks ago the drive train is making a loud clanking noise and the rear wheels are wanting to lock up when I try to start off. These problems don't occur every time, but the drive train noise is getting worse from all the feedback I see on this web site I feel I would waste my time contacting GM. All of us Chevy owners with problems needs to contact GM every day about our $30,000 and $40,000 dollar hunk of scrap metal. I hope mine will burn and I will not ever buy another Chevrolet product again. Here is there web site I have been calling the phone # on the web site, but it just stops ringing. You can send them E-mails and letters.

Frequently my 2003 Chevy Silverado hesitates to pull off after coming to a complete stop. I've taken it to two dealerships for the problem with the transmission. They state it is a problem with the computer programming which has the transmission pulling off in second gear instead of first and they have no solution for this problem, just keep driving.

: the contact stated while driving 10 mph and below, the steering allowed too much play and maneuvered loosely. The vehicle was taken to the dealer who replaced the steering shaft. However, the problem still exists. The rack and pinion had a slight leak. The consumer has had numerous components replaced on the vehicle such as wheel bearings, ball joints, tie rod ends, control arms, steering gear, shocks, steering linkages, coils springs, wheel hubs steering column and the power steering gear. The intermediate shaft was replaced three times and lubricated the last time. The consumer was told the steering design was flawed, which contains a looseness that can't seem to be corrected. The transmission hesitated at times. The dealer stated the clutches were burnt and glazed. The tires were exhibiting premature wear. Updated 08/02/06. Updated 04/16/08

The consumer complained about several problems. While driving he had trouble shifting from first gear. The dealer reprogrammed the engine control module and the transmission module control. The vehicle was still shifting hard, and the rpms revved. The replacement of the aforementioned did not remedy the transmission problem. The second problem was with the brake light coming on the cluster assembly. The service dealer replaced it, and it seemed to work well at this time. The third problem was with a noise in the rear of the vehicle. The dealer replaced the gear kit, two gaskets, case, the rear differential carrier assembly, carrier gears, and shims. The noise was still heard. The dealer recommended that the contact install carpet to cut down on the noise. The final problem was with a loss of rear traction. The dealer has been unsuccessful in identifying the root of the traction problem. The cruise control stopped working. Updatd 11/29/05.

When coming up to an intersection, the truck failed to come to a complete stop, in dry conditions, with ample stopping distance. The truck was revving at a high RPM, and continued to push forward with the brake pedal pushed as hard as possible. This resulted in a rolling collision. Vehicle finally stopped when shifted into park. Immediately called dealership, and GM. After 2 days in the dealership they stated nothing is wrong, and will not investigate any further. I will not drive the vehicle any longer after this scary incident.

I own a 2003 Chevrolet Silverado extended cab short box Z71 4X4 pick up truck. It has the 4 speed automatic with overdrive transmission. I have a consistant shifting driveline clunk that only occurs when the transmission upshifts from 2nd to 3rd gear and then downshifts from 3rd to 2nd gear. I have had this vehicle back to the Chevrolet dealer three times so far concerning this issue. All I get is the usual GM runaround that this problem is a normal condition and no repairs should be attempted according to the tsb related to this condition. I have owned other GM vehicles in the past, and I have never had of any of them bang or clunk from the transmission when shifting gears automatically. They claim that it is some type of a momentary torque reversal problem when that particular shift occurs that causes the clunking and or banging condition in their transmission. A momentary torque reversal in their drivetrain while the vehicle is moving in forward gears is a normal condition" not to me. They absolutely will not fix this problem under warranty stating that it is a normal condition. On the other hand, if this causes the transmission to suddenly lock up...and someone gets hurt in the process....then I'm sure that it will be fixed properly. Why is it that the automotive manufacturers today will not repair their engineered screwups at their expense, like they should be responsible to do? why is it that they will not fix their problems unless that componet in question fails completely"

Silverado 2500 8-cyl

  • Automatic transmission
  • 8,000 miles
2003 and up Chevrolet Silverado 1500 4.8L automatic I found I am able to shift the transmission out of park without the engine running and with the key in the accessory position. This is from no key inserted to inserting key and rotating to the accessory without going to the run or start positions. This can be done without depressing the brake pedal. This has also been verified on numerous 2003, 2004 and 2005 Silverado with automatic transmission but unknown engines at several dealerships. I was told everytime this is normal operation but was unknown to them prior to me bringing the problem up to them. This problem is consistent and occurs everytime attempted. Possible scenerio involves children in the vehicle with the key set to the accesory position to permit the radio to play while the driver exits to perform some task. The children could hit the shift lever and move it out of park permitting the vehicle to move. Again, this is possible without the engine running and without the brake pedal depressed. With the key in the run position, the brake pedal must be depressed to move the shift lever but never with the key in the accessory position.

Vehicle shifts hard and makes clunking sound in all gears. The transmission is constantly slipping between first and second gears and slams into second gear. Also having intermittent issues with truck slipping in first gear from a dead stop. There is a constant "knocking" feeling in the steering wheel when going over bumps and turning. Dealer claims nothing is wrong. I have been a loyal GM customer for years and am extremely dissatisfied.
