1993 v6 auto tranny issues

[LoveToDrive]

Hi folks I am a new poster. I have a 93 4runner v6 auto. My transmission is acting up on a non regular basis. The vehicle is driven about 100 miles daily. Lately when I am close to work I lose overdrive then it is sluggish in every other gear when I attempt to drive again.
I shut it off for a few minutes start it up again and it works fine. My speedometer tends to read really high or not work when this occurs. It was rather frustrating leaving work today not having a problem and only having first gear for a few minutes.
Seems like an electrical problem but my Haynes manual has next to no information for an automatic. Does anyone have advice or had a similiar problem. Thanks

Here's a link for a 93 FSM, it should help a lot.

I think both the EFI and tranny ECM's use a signal taken from the speedo, so there's a definete connection with the problems.

Is it throwing any codes? od light flashing?..........and that link he supplied is awsome I think its going to help with my problems as well....

The link was very handy thanks for sharing. It was a speed sensor. I lucked out and picked up a set of 31's yesterday from a retired mechanic that wrecks toyotas. He did the repair in about 20 minutes. Might be a sign to stick with the repairs on my 2 speed powerglide on my hot rod.
