I have a 92 4runner, auto transmission, 4wd.

A while back the transmission started to very slightly miss when shifting into the next gear. When going from 1st to 2nd (and 3rd to 4th) the engine will rev (up to about 4000 RPM) and then the transmission will catch. Because I was afraid to mess things up further, I parked it and started driving another vehichle.

Recently, I got back into the 4runner to test it out. After sitting for about 4-6 months, the problem has become worse. Now, the transmission doesnt engage until about 6000RPM before it shifts hard into the next gear.

One interesting thing is if I slightly let off the gas it will usually smoothly shift into the next gear. However, sometimes this doesnt even work. It does shift through all gears and once it reaches overdrive runs fine.

A few other problems I've seen:

* When I first crank it up, for about 1-2 minutes it runs really rough (as if the spark plugs are bad) and then all the sudden it idles down to normal.
* I have a problem with the spedometer sometimes (seems common on the boards) where it jumps down to zero and back to speed randomly.


Any help or advice would be greatly appreciated! I just want to find out if there is something I can check before I get the transmission rebuilt.

Corey,

Check the color of the fluid and report back

I have a brandnew rebuilt crate trasmission still with the plastic on it I will sell for $500.00 I paid over 1600 for it but sold the vehicle before the transmission arrived.
