ok... check your transmissino dip stick to see if the fluid level is regeresting on the dip stick. now this IS WHAT A LOT OF PEOPLE DONT KNOW.......NEVER I MEAN ....NEVER CHECK THE TRANSMISSION DIP STICK WHEN THE CAR IS NOT RUNNING, ITS OK TO CHECK YOUR OIL DIP STICK WHEN THE CAR IS NOT RUNNING.BUT YOUR TRANS IS DIFFERENT...... heres what you do...... START YOUR CAR...THEN PUT THE EMERGENCY BRAKE ON ...THEN PUT THE CAR IN NUTURAL....... NOW YOU WILL GET A REANING ON YOUR DIP STICK IFITS LOW THEN ADD FLUID.. REMEMBER ALWAYS CHECK THE TRANEE IN NUTERAL THE BRAKES ON AND THE CAR RUNNING.....HOPE THIS HELPS. GOOD LUCK...........

Sounds like a broken axle (CV joint) or your transmission has gone

Chances are is that the torque converter needs to be replaced. However, the transmssion on this vehicle are only serviceable by transmision shops. No regular mechanic will open up the transmission. When the torque converter fails (clutch and plates shutters to small pieces) the debri flows in the transmision thereby potentially destroying the gears and/or clogging the filter and pump. Go straight to a reputable transmission shop and let them correctly diagnose the transmission.

This is Ron out of Vero Beach Florida. I have been doing trannys for years. The problem you described is caused (more than likely) by a seized clutch pack. Depending on the trans, and your car should be RWD with a 700r4 tranny, there are several sets of clutch packs and at least one band. Automatic transmissions rely on fluid pressure to "engage" the correct set of clutch discs, at the right time , to engage and change gears. I have seen in the past, where a customer parks his car for the evening and the next morning, no move. What happened?? More than likely, a clutch pack was on it\'s way out but cause the car was hot the plates were free, but after cooling, they can weld themselves together and actually "lock-up". In the morning you know the end result. Your tip on "moves in Nuetral" is the give away. Ron
