One problem related to transmission gear slipping has been reported for the 2002 Chevrolet S10. The most recently reported issues are listed below.
I have a 2002 chevy S10 ext. Cab pickup truck with a vortex 4. 3 litre eng. With automatic transmission. While baking out of driveway I noticed I had no reverse gear, it is also slipping in all other gears. This truck has never hauled anything heavy and only has 49,500 miles on it . I got down to the stop sign and tried to proceed and the forward gears started to slip and I couldn't get out of the way of oncoming traffic and almost got hit by an oncoming car. I have heard and talked to many other people who own these vehicles with the 4l60e/4o65e transmissions. I feel these could be dangerous. They seem to all have the same sun shell and sun gear problems. I feel general motors should re-call them.
