S13 KA24DE Auto acting weird

I have 92 s13 and after it warms up a bit and I'm driving it will just randomly rev up and down back and forth. It idles completely fine. It only does it when the cars warmed up and under load (driving). So far I'm thinking it's my trans and I also believe my overdrive doesn't work because my car is completely stock everything and runs at 3k rpm at 70mph... Please Help!

Probably your torque converter.

Autos suck.

Something is slipping, you can try some "trans slip fix" from a parts store, but you're likely on borrowed time.

First thing I would do is check the fluid level.

Whats the mileage and when was the trans fluid last changed?
