<font color="blue"> How much is the NH repair manual anyway? </font>
It's actually a set of repair manuals and they wre $156 when I bought them about a year ago.
Super old post but this seems to be a problem. I'm going to attempt to fix on my ford 1620. Sticky pedal, also goes faster in reverse. I believe that the hst link has to be lengthened and the return spring re-adjusted to correct. See attached description. It may help.
