Recently pulled the motor to rebuild due to knock (believe its a wrist pin). To do so, I had to remove the tranny modulator to remove one of the bellhousing bolts. My question is; is there anything specific I need to be aware of when I re-install this modulator? I've never really messed with one before and it has a retainer and bolt sort of like the old distributors do. It doesnt appear as though anything needs to be timed, but wanted to make sure. Mine is the larger grayish modulator.

Nothing special take it out and put it in after you are done. Nothing to adjust. the gray ones are original ones and are not adjustable, (anyway they don't have to be adjusted when you take them out) the gold ones (smaller in size) can be
adjusted if you wish for harsher or softer shifts by inserting smaller flat head inside of the vacuum line fitting and turning screw inside 1/4 of the turn at the time and testing for desired shift points.

Excellent thanks! It didn't look like there was anything to worry about but wanted to make sure. I really appreciate it..

No problem, just make sure you connect all the vacuum lines to it or you will not have ac, or heat :grinno:
