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.
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 truck was parked and the key was in the accessory (acc) position, and my two year old granddaughter hit the shift lever out of park, and the truck rolled down the street and hit a u-haul truck, she was not injured, her mother was in the truck with her but could not shift it back into park, or hit the brake.
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.
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 Silverados 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.
We have had several thing go wrong with our truck. We have had the expandable mirrors replaced once and fixed several times, the transmission was rebuilt, the speedometer quit working and the memory does not recall the driver or seat position.
Transmission shifts hard from 1st to 2nd gear. This may cause a loss of control of the vehicle on icy roads.
Transmission shifted through all ranges while in first gear (low) would not down shift to pass.
Drive line "clunk". Appears to be too much play in the drive train. Clunking sound when automatic tran shifts. Been to two dealers 4 times. They say it's "normal". Talked to gm and they say it's "normal".
Clanking in transmission between 1 and 2.
2003 Chevrolet Silverado the truck will shift in 4 low while driving. The service 4 wheel drive light will come on. The truck has been to the dealer,dealer can not give reason why the truck does this or has been able to repair it. Sooner or later this truck will cause a accident when it pops into 4 low on its own.
Transmission clunking in 2-3 up shift or 3-2 downshift, mush louder when towing my trailer it sounds like its going to exployed brakes: brake pedal is on the floor very very weak cannot stop truck on a quick brake 2003 chevy Silverado 4x4 xcab.
Problem with transmissiopn hard shift from 1 to second and at times wont shift until you release gas and step on gas again. This happens at any time and with any road condition.
Harsh 1-2 shift slipping 1-2 shift followed by harsh engagement.
While driving the second gear of the automatic transmission didn't shift properly. The dealer inspected the vehicle but could not duplicate or correct the problem.
While driving 65 mph the vehicle shifted from 2 wheel drive to 4 wheel drive low. The dealer was aware of this problem and stated that the manufacturer had no remedy for it at this time (2500 hd).
Transmission has rough studder/slippage when shifting from first to second gear. It doesn't occur every acceleration.
Power train & transmission, clunks & slips quite often on acceleration and sometimes will downshift unexpectedly at lower speeds.
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?.
Transmission bangs into gear, sometimes it is so violent it causes the rear wheels to break loose causing reared to become unstable, been to dealer 3 times , they say this is normal. This problem becomes worse the longer its driven. Very scary to drive on wet roads.
The vehicle shifted into 4 wheel drive without warning.
At low rpm the transmission will free wheel after stop or between low gears. After stopping the truck will raise rpms, but not move, then drop into gear. Runs fine for a while then without warning can re-appear. Has been a major factor in two near-collisions when exiting shopping areas and finding no power connected as truck rolls into intersection. Has also rolled backwards once only on uphill when transmission free wheeled. Has been presented to dealer four times (five but once did not even look at) and can not duplicate problem. Once also to dealer because brake petal went to floor while stopped at intersection - was told this was a normal function of the anti-lock braking system. Date is of first incident.
