Six problems related to transmission gear slipping have been reported for the 2003 Chevrolet Silverado. The most recently reported issues are listed below.
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.
Problem with transmission hard shift from 1 to 2nd and at times won't shift until you release gas and step on gas again. Sometimes when taking off from a stop transmission slips, causing vehicle not to move, then engages when rpms is high causing vehicle to jerk into gear.
While driving transmission slipped gears, causing the consumer to drive in first gear. Dealership repaired the problem once, but problem recurred.
While driving between first and second gears transmission slipped intermittently, causing vehicle shutter violently, and became very hard to down shift.
When taking off from a stop transmission slips, causing vehicle to fail to move, then engages when rpms is high causing vehicle to jerk into gear. Can be very dangerous when pulling into a intersection and vehicle fails to move. I have almost wrecked several times because of the delay. Does not happen all the time dealership has been notified 7 times and failed to fix it.
The transmission slips when either starting from a complete stop or when shifting from 1st to 2nd gears. You can feel the truck then jerk into gear when engaged. Note: this is an automatic transmission and does not do it on a consistent basis. It seems that temperature or road conditions are not a factor. I have taken the vehicle into a Chevrolet dealer 5 times and the problem still persists. Dt.
