Ok, I'll start off by saying transmissions are voodoo to me. Thats why I pay to have someone rebuild them.
I just installed my rebuilt (by local guy) 727 into my 440 R/T. The problem is you have to rev it up high to get it to make the 1,2 or 2,3 shifts. If it shifts at all. The kickdown is adjusted to be all the way back when the throttle is fully open.
Also I had to see if the Six Pack was opening, so I goosed it for a little bit and let off. When I let off I went to give it gas and it went nowhere. The only way the car would move is first or reverse.
Frustrated I parked it overnight. The next day the transmission worked and shifted in all gears. But still needed to be reved high to shift. I'm guessing it has to come back out. And maybe send it to Cope. But does anyone have any ideas before I have to cut my brand new exhaust back off? Thanks
