had this happen on mine when I installed the first T-A valve body. Luckily, my car was still on jack stands when I found it. Talked with Paul Forte about it over the phone, and he was convinced I had done something wrong (as was I), but agreed to take a look at the valve body, so I sent it to him. He called me a week later, said he had installed it into his test vehicle and it did the same thing. Locked up in D. He appologized profusely and sent me a new valve body which worked fine. My point is simply that it could be in the valve body (???).
I checked the cable adjustment on the shifter.. that was perfect
and I checked the band adjustment which was good.. it still locked
up but its on the hoist now...now I'm getting ready to drop the pan
and the valve body... I'm gonna do a air check on the servo to see
if its moving freely and for a crack in it
EDIT
Anyone have any other ideas before I drop the pan.... by the way
I checked the cable in low and in drive positions and both were
perfect
