Default A518 TC Lockup Switch?

The TC seems like it wont unlock on my 92. I tried to drive it around the yard for the first time today and the second you shift into Reverse or Drive the TC seems locked up and it pretty much stalls the truck.

Could there be a TC lockup switch on it that i havent found?? I don't even know if the 518 can have one. Any help would be great!

Yep i did some research and found that out so now im even more puzzled.

I just got back from the track and started the truck up to show my buddy what it was doin and it worked fine! Seems to be that it's only when i let the truck warm up it does it. Could it be something to do with the trans cooler?
