Locked converter

I have a 96 F250 psd 2WD and it acts like the converter is locked up completely. If I drop it in gear it will stall the engine unless the wheels slip. If I can get it rolling with out stalling it shifts just fine, both up and down, and if attempting to stop it will stall.

Acts to me like something in the coverter came loose and locked it up. Do you all think a new converter is the answer or is there more to it? E4OD right?

Ok I unplugged the connector, started it up, dropped it into drive and it acted weird but wasn't locked. I then put it in reverse and it still wasn't locked. I went back to drive and it made a tinny mechanical crunch and locked enough to stall the engine. After restarting, it was back to being completely locked again, both forward and reverse.

Acts like what is wrong in the converter just happened to come loose and then it jambed up again. I'm still thinking something came loose inside the converter and has it jambed/locked up. Unless someone thinks otherwise. Let me know if you do.

Idle and park it runs just fine. And if I can get it rolling then drop it in to gear it drives and shifts good

How about reverse?

If its good in park and reverse then the good news is that you TC isn't mechanically trashed, but you still have an electrical malfunction or hydrualic malfunction/internal leakage.

Seems to go in reverse just fine. I am hoping it is the converter because I have another for it. I just don't want to be doing a lot of useless work.

I haven't tried actually driving it after unhooking the harness. Maybe I should?

unhook the batteries for 10 minutes then hook back up. Does the OD light on the shifter work? does it flash?

The TC won't lock unless its told to. For some reason it being told to at the wrong time if thats what really is going on.

OD light works and doesnt flash. Would the converter be locked with the harness unhooked? Barring hyd probels that is.

It shouldn't be but who knows considering the problem your having.

Does the problem change at all if you shift to manual 1 or 2?
