Re: Ultramatic leaking from the manual valve seal.

If the motor does not move the selector when pushing drive (or any range), a common problem has been inside the PB assembly on steering column -- broken contacts -- or the white plug at base of steering column has had one or more contact pins work loose.

If the shift motor moves but trans does not move car in D or you said possibly L, then very likely adjustment as bhappy said -- even with tight bolts. Manual valve being solidly centered in the detent is critical with the electric shift. D and L both need the low range servo when selected but none of the other ranges do. If adjustment is OK then loose inner lever giving some slop to valve, or other issues could be preventing proper operation.

The adjustment screw on actuator only controls hunting. If you push a button and hear more than one or occasionally two relay clicks when it reaches a gear then it might need adjusting because selector is not stopping quickly & is overshooting and has to reverse. If not hearing extra clicks then it is OK. If it is adjusted too tight, the extra strain on the motor could cause more problems--even to the point it can't overcome the occasional binding that sometimes occurs when on a slight incline or some other load is placed on the park pawl.
