Vacuum Regulator Valve

[Nowhereman]

I replaced the vacuum regulator valve a few days ago on my M1008. Man what a world of difference it made, gears shift smoother, 1st gear shift at around 15 mph and 2nd at 30 mph. The old one was all gunked up looked like it might have been the original factory one. Here's the part # if anyone needs it ( AC DELCO # 14057219).

I have one new one left in my stash. It is strange how much better the CUCV shifts after replacing all the rubber lines and the TPS and trans modulator valve.
Being 25+ years old they gave up the ghost years ago.
Also check the vacuum pump

Glad to hear that. I had shifting issues of own. Turned out to be a kinked vacuum line. Still need to readjust the regulator though. As if now 2nd and third kick in way early.

It seems that when one thing goes bad everything goes with it.

The rubber hose on mine connecting the steel line to the valve had completely rotted. Line was disconnected. I hooked it back up with a new hose piece and it works great. Truck has 92k miles on it.
