Vacuum Reg Valve, need it?

[HAWKMAN]

How much trouble will I get in if I eliminate the Vacuum Regulator Valve and hook directly to pump,I just need to move truck a short distance and VRV isn't allowing vacuum to the trans modulator....bites driving it in second gear.

you can drive without it, the trans will shift at HIGH rpm's and HARD AS HELL. But, it will not hurt the transmission at all.

Thank you VERY much! apprieciate the info.

on further thought, just unhook the vacuum lines from teh trans entirely.

That didn't work for me, no 2-3 shift at all, even at 60+. Drinks fuel like a watering hole camel with out 3rd...

The vac or modulator don't have anything to do w/shifting from 1-2-3 just when and how hard it shifts. Sounds like you have a problem in the valve body of trans.

IMHO, bypassing the VRV results in very early and soft shiftings.
