How is the transmission fluid looking? When was the last time you tuned it up? There's lots of variables to consider.




I checked the transmission fluid and it looked good.. I just bought the car it was parked for two years I have not gave it a tune up..

Common issue with the AOD transmission when the O/D band is worn and burnt. Keep the O/D locked out so you avoid the shifting. Save your money till you can replace and or rebuild the trans.

If it sat for that long its best to change everything. All fluids, filters, plugs, wires and flush the radiator. They are super fun cars to drive. But why was it parked?

Bought it off an older lady who had no use for it...she just had it parked on non op...
