Recently our Rendezvous has had a problem where when moving from park to drive or when at a stop light the car is VERY sluggish. Eventually it will take of abruptly until the next stop light. I have checked the fluid and there is enough and it doesn't smell "burnt". I have had the transmission serviced every 30,000 miles but have never had the pan pulled off. Is this a repair job for a transmission shop or will it need to be preplaced? We love the car and really want to keep it.

Thanks for any information,

If you feel the transmission is slipping bring it in and have it checked out,otherwise-see below:

Lack of acceleration,chugging,hesitating,bogging,misfiring etc. could be caused by one of the following below:

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.

Note:If it doesn't apply disregard it.
