The transmission failed with no warning. According to tsb 00-07-30-022 the 4l60e a/t will lose reverse, 2nd, and 4th gears. This is caused by a defective part in the transmission called the reaction sun shell, which was returned to me by the transmission rebuilder. The failure was not maintenance related in any way. The failure of the part was due to inadequate strength. There are numerous aftermarket reaction sun shells that are much stronger and durable than the defective gm part. This problem is widespread and could create a dangerous situation. The transmission will only shift from 1st to 3rd if you accelerate quickly in 1st then let off the accelerator. I pulled on to a high speed highway and could only maintain 25 MPH with no place to pull over, until I realized that it would shift to 3rd if you let off the accelerator. Several vehicles had to swerve to avoid hitting mine. This can create a dangerous situation if someone tries to turn around and needs reverse or needs to drive at high speed such as on a limited access highway. Gm should recall all vehicles that the tsb applies to. They know about the situation but do not want to issue a recall because it would cost them too much money.

Consumer received several recalls for 1996 chevrolet s10 blazer. *mr the vehicle's heating/cooling system and transmission failed prematurely. During a routine check the consumer noticed that the dex cool coolant had turned into a reddish clay-like substance. Given the condition of the coolant the consumer proceeded to flush the system.

We have experienced transmission problems starting in 12/98. At this time, our truck was still under warranty, and we mentioned that the transmission was slipping when our truck was serviced at wilton motors. The mechanics insisted it was fine. In fact, we are not even sure if they checked since our service invoice indicates that checking the transmission was a "deleted operation". On 2/25/00, the transmission failed while driving on the highway. It was constantly slipping and could not handle highway speeds (the truck was having trouble shifting gears and made a grinding noise). We brought the truck into an independent specialist on 3/2/00. The entire transmission needed to be rebuilt and several bands were replaced. The entire repair cost $1,800. We were not satisfied with the service at the gm dealership, and were concerned that they would now find a problem with the transmission and charge an even higher amount than an independent specialist. At this point, our truck was no longer under warranty. However, we felt the problem had developed while the truck was still covered under warranty, and the gm mechanics failed to find the problem. We have filed a complaint with general motors on 4/12, a complaint with the better business bureau on 6/12, and are now filing a complaint with the federal safety agency. We have spoken with other owners of 1995 and 1996 blazers, and many have complained of transmission problems. We are hoping that gm realizes there is a problem with this part and will investigate other complaints on the transmission. We have already had 5 recalls for our 1996 blazer, and we are hoping there will be a recall for the transmission.
