e4od won't shift into 2nd intermittent when warm

97 f250 7.3L 4x4

E4od won't shift into 2nd intermittent when warm. It will hold first gear until you let off the gas pedal. Trans was rebuilt about a yr ago. It has a brand new converter also within the past month under warranty.

Anyways it seems that the Trans its doing what the computer commands. So the computer isn't commanding a shift until the gas pedal is released.

Throttle position sensor? Or speed sensor possibly?

How is the fluid, is it still bright red and unburnt?

Have you hooked a code reader to the truck?

what prompted the new torque converter, did the other one blow up?

it sounds like something is sticking in the valve body, usually caused by gunge floating around from components breaking down.

Converter took a ****/ started slipping, trans was pulled, trans was pulled apart and gone over to check for carnage in frictions from converter. All was good. Converter was replaced, trans was reinstalled.

Mine was doing the exact same thing, and I took the valve body apart, and cleaned it (there was a lot of fine black stuff in it), but also gave it a shift kit, and now its shifting as good as new.

It probably didnt need the kit, but since I was taking the valve body apart, I didnt want to take it apart again later to put a shift kit in it.
