I rencently put a 289/c4 combo into my 65 mustang. It came out of another mustang of mine. when it was in the other car, the c4 would not start off in 1st (started off in 2nd) unless you put it in 1st and reverse would engage kinda hard. when it was pulled out of the car, my father was gonna use it in his so we got a rebuild kit and instruction video and he rebuilt it. He followed all the instructions and put it all together. The problem is, now it doesnt have reverse at all. All the linkage is right, its got all the fluid. i havent driven it, but Drive engages, reverse doesnt. what do you guys think. He adjusted the bands according to the video. do you think it might be the band adjustment? any ideas?
