I have a 94 Cutlass ciera that the tranny is acting up on.
It is an overdrive transmission. 4t60e

Heres what it does.
When you put the car in drive you feel it go in gear.
I step on the gas and the engine revs up and you hear the tranny slipping and the engine revving up and down, If you rev the engine up high the car will start to move once it gets to moving it seems to shift into 2nd and on up fine. It only acts up in 1st and reverse this way.

I've had some people tell my it could be the computer so I bought a used computer and it still does the same thing. Some people told me that the computer has a separate computer others said it doesn't. There was another computer looking box in front if the main computer box (that I replaced)
What is this box?

I was also told it could be the modulator. Do computer controlled trannys have a modulator? and if so where is it at?

Please Help!
