Automatic Transmission May Not Shift Correctly at High Mileages on Toyota Land Cruiser

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.

When shifting from park to any gear there is a huge hit. Some mechanics say it's slack in the tranny. Some say in the transfer case or rear end? Been doing it for 75k miles...
The engine has 150k miles since rebuild. Tranny has a full 340k!
Just started not wanting to upshift. Isn't an every time driving issue but at least once or twice a trip.
