My trans builder said the governor slides off the front of the mainshaft requiring disassembly to change it.

I have the wrong one in my ford Van and it needs further delay before upshifting (like a trailer tow mode).

I did something to it in the '80s as installing a Mister Shifty kit from Napa, did not remove the transmission. I forget details.

Even though this is an old thread I have decided to try my luck. My 88 f250 2wd seems to not have a 3rd gear. It doesn’t even make an attempt to shift up, the only shift I get is at 22ish mph and 2200rpm, then what I believe to be second takes me up to 65 but I’m holding it right over 3k rpm. I replaced the vacuum modulator and there was no needle in the old one to swap out. I figured if the modular didn’t work then it would be time for a rebuild, but I was told to try the governor before resorting to a rebuild. Thoughts?

If there is no pin in the modulator it fell out during changing, at some point in time on an attempted repair. Doubt if it will ever shift to 3rd, surprised it makes a shift to 2nd unless manually selected.

Before I changed the modulator if I wanted to upshift I would just have to let off the throttle around 20mph and 2200rpm. After changing it the truck will shift without me letting off but it’s a super slow shift unless I do let off. As for 3rd gear, will I never see it unless I opt for a rebuild?

I have a C6 in my 71 f250. Having similar problems at others posting here. The trans is newly rebuild with about 50 miles on it now. Shifts smoothly, but unless I let off the accelerator momentarily, it will not up shift into second and never seem to shift into 3rd. Any ideas? It has a new modulator, pin, and good vacuum.
