Have you ever had the tranny serviced? Filter and ATF change only,
before spending big bucks on auto. transmission repair ($600 -$2000). You might want to get the computer scanned to see if there are any generic or manufacturer specific DTC error codes to include pending. Many times a tranny problem will not give you a SES light but hold certain codes for future reference, etc.

Is the car upshifting or downshifting normally? Do you get any shudder when accelerating hard from a stop? Is the torque convertor locking up properly when you are in overdrive (4th gear).

If you have the V6 or 4 banger your tranny should be a model 4T45E.
