833 Transmission won't disengage at stop after 100 miles.

for adjusting the Hurst shifter on an a-body, use a 1/4"(IIRC) twist drill shank inserted into the holes in the shifter's fwd gear levers to position the 1-2, 3-4 shift levers properly. However, I've always found that the reverse lever never seemed to line up and shift properly, so I adjusted it totally separately from the fwd levers.
