Hi,
New Sierra with 9500 miles. Transmission has never been right, at first service complained that it lurches at low speed, such as parking in a parking lot and feeling like I've hit the concrete stop. Also noticed that when approaching a stop light, at 2-3 mph before stopping the truck will lurch. Dealer assured that they needed to change some 'codes' in the transmission.
Now the transmission slips when it's cold. Upon starting, the first application of the gas pedal after a shift into gear (whether forward or reverse) results in the engine winding up as if it's in neutral. After a second or two, the trans will "slide" into gear and the truck will start moving. Reminds me of my old Willy's when the clutch was worn out and would slip.
I'm getting ready to send the truck back to the dealer - any suggestions on what to tell them or other folks that have had a similar experience? Anyone know of any service bulletins addressing this problem?
thanks guys
