once i am at a complete stop and i get ready to go the car will take a moment and then jerk. I have also found that i am having problems with it shifting to the next gear. We have had it checked several times with no resolution. I don't understand why this isn't being recalled it seems to me like i am not the only one with this problem

The transmission issue of shifting erratically just started but only when the car has been on the road for more then 30 minutest or so. Was checked out through a Chevrolet dealer and told it would cost $1000.00 to fix the solinoid issue. I would like to fix it myself.
If I dont come to a complete stop and accelerated the gear takes a second to engage and causes the car to lurch forward suddenly with a slam making it feel like i was hit from behind.

Everytime my speedometer stops working on the dash my transmission stops changing gears I was wondering could this be an electrical problem or do I need to replace my computer

Car hesitates and bucks when I begin from a "rolling stop." If I COMPLETELY stop for about three seconds and THEN try to go, usually it will work fine if I start really slowly (can't gun this car at ALL anymore...). Sometimes, I can feel it shift down when I'm stopped for a bit longer. I'll get a hard shift while moving every now and then, but the worst problems are beginning from a short or rolling stop and trying to accelerate to turn. When I accelerate to turn, it will act like it's dying, then suddenly engage and go.

Erratic shifting took it to a transmission place and had the celenoid replaced
