Three problems related to noises during shifting have been reported for the 2003 Chevrolet Silverado. The most recently reported issues are listed below.
When shifting from the second to third gear a loud banging noise was produced. Dealer has rebuilt the transmission. C urrently, when shifting first gear to second gear a loud noise is produced. Consumer is concerned that the transmission will fail while driving.
Transmission slips between dead stop to second gear-more noticeable when wheel is turned. "clunking" noise when shifting. Dealer was unable to find anything wrong. (2003-2500hd crew).
I am complaining of a clunking sound and a hard shift coming from the transmission in a 2-3 upshift in a 03 Silverado automatic. I have taken it to the dealer many times and they tell me that gm says the noise and shifting is normal. I have driven many cars and nothing I have driven shifts like that. I wish gm would have to do a recall and correct the problem.
