Weird 727 problem

Do not start the car!!!!! That adjustment is critical. If the square adjuster is rounded, you will have to make a tool that will fit on your torque wrench and fit on the adjuster. Better yet, get a new adjuster. This adjustment has to be right. As said earlier, your transmission won't last very long without this adjustment being right.

Jack is dead on. If that adjustment isn't right it'll trash the trans. in a heartbeat. What will happen is the trans. will try to be in 2 different gears at once. That just don't work. It could even grenade the trans.

As far as the adjuster being rounded it is a square head that has rounded corners and takes a square 8 point socket. It would be nearly impossible to round that adjuster off because it's hardened steel and the band strut would either bend or you'd break an ear off the band before you ever stripped the adjuster. Exceptions do happen of course. Like if somebody tried to crank it down with the locknut tight. Try an 8 point socket on it and see what happens. I think its a 5/16" 8 point that fits if I remember right. If it is stripped I probably have an extra out in my spare trans parts I can send you. Just pm me if you need it.
