Automatic Transmission May Not Shift Correctly at High Mileages on Toyota Previa

Problem Description and Possible Solution

At higher mileages, (125,000-150,000) the automatic transmission may not shift correctly. This can be caused by the throttle position sensor being out of adjustment or a shift solenoid needing to be replaced. Typically the transmission does not need to be completely overhauled.

ATM warms up and fails to shift. We have replace the speed sensor and rotor sensor but the problem persists
This just started three days ago. It was running and shifting just fine one day and the next, it was having problems shifting, surging. I thought it was cap and rotor, but this may very well be it. I will investigate more tomorrow.
