One problem related to transmission gear slipping has been reported for the 2000 Chevrolet Blazer. The most recently reported issues are listed below.
Transmission slips, 38kmiles on my 2000 Blazer, out of warranty. Took it to the dealer, the dealer's mechanic said he has replaced a valve on the transmission of four 2000 Blazers so far this year. I will make number five - quoted cost of $850. Service center will not cover under warranty. Read several reports about transmission issues similar to mine on 2000 Blazers and s-10s. Why no recall? if this is a known problem, why am I not coverred under extended warranty?!!.
