The automatic transmission may not shift correctly. This can be caused by the throttle position sensor being out of adjustment or a shift solenoid needing to be replaced. Typically the transmission does not need to be completely overhauled.Google+

Transmission will not shift correctly. Sometimes will not shift into reverse, drive, 2, and low. It is as if i am in neutral, the RPM's are moving but the car isn't. I have not fixed this issue as of this report.

SLAMMING TRANSMISSION ON TAKEOFF. HARD SHIFTING, GETS A LITTLE BETTER ONCE THE CAR IS WARMED UP 1/2 ON TEMP GAUGE, BUT DEFINATELY STILL SOMETHING WRONG.

Same problem as reported by others. When attempting to accelerate the car will be slow to respond and then downshift hard with rpms surging. Problem is worse with cruise control and cruise calls for acceleration.
doesnt shift into gear right away after you stop, then slams into gear and jerks forward

Car jerks into reverse, doesn't seem to catch gears and revs super hard though not accelerating
Slamming shift on takeoff, then at 7000rpm spuuters, won't shift until you release accelerator slightly. If car is allowed to warm to 1/2 of temp gauge shifting is much better. Erratic shifting.

I made a stop and as i accelerated the car stopped amd slammed forward. Would not move in d,r, or 2 gear. Made it home in 1st. When in those gears the rpms will move but the car doesn't. I am having the transmission rebuilt. Other than switching gears more slowly or not as smooth the car seemed fine up until yhis happened.

Hard shifting and misses gears.
