I put a 700r4 in my vette, behind a 350. When installing a B&M shifter, I discovered that the shift lever on the tranny is very hard to move. The new shifter will not move the lever from park and such... Its hard to move by hand also. I know there is nothing wrong with the shifter. So, is there something wrong with the tranny? I've connected the tv cable, made sure the tranny is full of fluid. Still hard to move lever. Help? kip
