Happy New year to you all.
So I swapped a th400 into my truck where I removed a BOP th350. Same length so no driveshaft to cut but changed the yolk for the bigger shaft . Problem is this trans pulls forward in P,R,D,2,1. N acts like P. I have B&M speed shift In floor but i can shift by hand from underneath without shifter connected to the same outcome. Trans worked fine in van it was in with about a 6 month sit before I needed it installed. Will not roll backward in any way. Has anyone dealt with this before and thanks for any insight in advance. It's my daily driver so I need it on the road asap.
