Automatic Transmission May Not Shift Correctly at High Mileages on Toyota RAV4

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.

I just bought a 1997 automatic Rav4, when i accelerate above 60 mph on the highway it gets stuck at 4000 rpms and after 5-10 minutes it will shift back down to 3000 rpms.
I will be driving on the interstate and at 60mph the rpms will be about 4500 or 5000 and get stuck before shifting down and then stay at around 3500 and I cannot accelerate past 80mph.
When driving on the high way the engine revs starts going down and the gear shifts down. Had to stop, switch off the engine than start again
On my 3rd transmission and 4th computer. Dang this is annoying. Keeps slipping (first when cold, later more often, and finally will not go into reverse or high gears). I'm beside myself on this one and selling the car while it's still running. LOVE the RAV4 of this year, but I can't trust it and I'm thousands into repairing it so often.
I have no soloution but I'm having this problem and it's really annoying trying to drive on the highway.
Transmission not shifting correctly. Shifts at 4000 rpm. Added transmission additive. Waiting to see if it helps.
It sounds like a growling noise, and my mechanic says the entire transmission must be replaced.
