I just rebuilt the transmission in my daughters 1990 2.3 now you have to rev the rpms up to get it to move. any ideals anyone

Usually when you have to rev it up to get it to move, that means slippage. Since you just rebuilt it, it could be a simple fluid flow problem or a drum isn't operating properly. Might need to check it to make sure something wasn't left out or that you're getting fluid flowing to the area. Did you replace the pump? That could also be the problem.

1) Kickdown cable damaged, over adjusted, or the internal kickdown linkage needs adjusting.

2) Improper clutch or band application, or oil pressure control system.

3) Dirty or sticking governor.

4) Dirty or sticking valve body.

Did you throughly clean the governor? When I rebuilt mine, I had to go back in and really clean the governor good. When I cleaned everything up the first time, I did not dissassemble the governor. After I cleaned it up good the second time, tranny works fine.

Of course first thing would be to check filter. While in the pan, if you find any black flakes, chances are the bands are coming apart.
