THE TURBINE SPEED (PART OF THE TRANSMISSION CONTROLS) SENSOR IS THE CULPRIT HERE, REPLACE IT.

check your tranny fluid and filter. you may have a clog some where or could be low on tranny fluid.

Try changing the transmission fluid and transmission fluid filter. It is a fairly easy but kind of messy job. Just buy the new fluid and filter, Grab your metric socket set and go at it. NEVER WORK UNDERNEATH A HOT VEHICLE. You have to pull the transmission pan to do this job. When you break the gasket seal several quarts (liters) of transmission fluid will cascade down on you. Be ready for it. Don't forget that when it stops draining there is still a lot of fluid left in the pan. When you finish cleaning up the fluid clean the gunk out of the pan. Install the new filter and reinstall the pan with a new gasket. Do not over torque the pan or filter bolts. If you strip them out or break them off you will need professional help to repair it. Refill the transmission with fluid. It should take six or seven liters.

I have seen alot of governor pressure issues whith those and sometimes the oxygen sensor can short out they share the same ground so if whoever works on this changes governor solenoid and pressure switch bring this to there attention and change the 02 sensor at same time.
