On my new chevy Tahoe, 2007, the transmission has slipped several times (50+) over the last 20,000 miles. Each occurrence was minor and when mentioned to the dealer at normal service intervals was told was common for a truck (I. E. They are stiff when cold, can do that when you go around a corner, etc. ) this finally culminated with complete transmission failure while in traffic. The repair offered by chevy is to just replace the defective part with a like part that the mechanic believes is not different. Hence we swapped a failed defective part with the same design that I must assume will fail again! this is not a fix and only delays the inevitable once again. Maybe next time it will break when passing or out in the middle of no where? the gear is called a sprag gear and all the gm dealerships are silently aware of the problem.
Transmission slips. Moving from park or reverse to drive - especially in the morning. Transmission slips when hard accelerating. Taken to dealer twice and they are unable to locate a problem. No computer codes. Respond that everything is fine. Updated 10/10/07.
