Sound like you're going to need to drop the transmission pan so you can replace the filter along with fresh transmission fluid. I had a problem like that many years ago, this correct the problem... I also know that the throttle positioning sensor will also cause transmission shifting problems. I would start with the filter change then go from there... Good luck.

The Transmission Control Module also turns on the check engine light. However the parts store won't be able to read these codes since all they read are the Engine DTC's. More then likely your codes will come back to a Governor Pressure Sensor and/or Switch. If they do then remove the pan and replace both of those. Simple fix, should be able to be done in about an hour or so. Might as well go ahead and slap a speed sensor in while you're under there. Should be able to do it yourself for less then $200.
