Gentleman,
Having received some great advice from a previous thread and read up on what I could find, could I just ask if someone could confirm what I believe is the right steps to correctly fine tune the Modulator and the modulator linkage rod on my transmission, that is currently working pretty well, but is just a bit harsh at times.
1> Check timing to ensure good vacuum
2> Get the transmission guy to adjust the Modulator pressure, via the Modulator Pressure Adjustment screw until we have 40 PSI showing from the port.
3> Then shorten the Modulator push rod until the pressure starts to rise above the 40 PSI and then lengthen it until it starts to fall,.
4> Set the rod length to that transition point
5> Reset the modular pressure to 40 PSI and go for a drive.
6> If this results in harsh changes, then reduce the modulator pressure ½ tune at a time until it improves.
7> If this results i slipping or “soft changes, then increase pressure until it improves.
Is that the correct procedure? Is the order correct?
From what I have read, these are good transmission and if set up correctly, an give almost imperceptible changes not far off that of a modern cars.
Is that right?
Many thanks.
