Sounds like the kickdown switch is stuck, or the wire is shorted, or something. Try unplugging the wire at the right/rear of the tranny?

Low fluid will prevent shifting also.

Check either the kickdown switch or the bowden cable. There should be some slack in the bowden cable. It's a cable coming from the tranny to the top of the valve cover. It gets pulled when the throttle is pressed. If it is too tight, the shift points will be REAL high and you may think that the tranny doen't shift at all.

I didn't think mine was shifting... until I got it up to 3500 rpm, then it did.
