I recently bought a '65 Mustang with a broken 289ci; I have switched the engine to a '92 roller 5.0 and it's working fine, but, I was told that there was C6 already installed in the car. Indeed, is not a C4 and I think is not a Cruise-o-matic. I just installed a B&M shifter, which fitted perfectly using the C6 set up, but fr my surprise, I have no 1rst gear!...there is Parking-Reverse-Neutral-Neutral-Drive-Second...I've stend 2 days repeating the set up and checked the gears manually on the transmission lever by hand and no, I just got 2 foward gears....any advice of what's going on?
