I am installing a Gennie Shifter on a B&M 350 trans and I can't get it to position right with the transmission. If it is set up and adjusted in the "park" position the reverse position is not right, meaning the shifter does not hit the detent exactly and slips out of position. If it's adjusted in the "reverse" position the park position does not fully engage on the transmission, it needs to go back futher. It's as if the detent plate (gate) is off somehow, but I doubt it. The rest of the gear positions from neutral on down to low, seem okay. Gennie is not sure why and is sending another detent plate. With my luck, this ain't a-gonna be the answer. I have changed the positions of the arms, on the spline, moving the shifter on it's axis, etc. etc. Most of these positions only change the distance between the transmission arm and the shifter arm and does not change the geometry enough to allow the extra 1/4" or so that it is off. Could it be the B&M Transmission? Anyone ever had this problem? Thanks for any help.
