After completing the TPI swap on my cutlass I've been having some issues with the TCC lockup. The main problem is that right after shifting into 3rd (usually about 35mph or so) the thing locks up. I'm still running a 200-4R, and I checked the wiring with the TPI's wiring and everything seems correct. The only thing I can think of is that I have the wrong pressure switch in the tranny. Does that make sense? If so, does anybody know the part number for it? Thanks.

 

Monkey,
Put a switch in the line,then you can chose when to lock it
