Re: 87 V20 D/D and Road trip Burb

Actually, that pic from coming down from 5 fingers hill reminds me. When I am going downhill in 4lo in 1st gear of my th400, it will feel like it is uplifting into 2nd. The shifter is in 1st. After 20 seconds of downhill, it will start to coast, no engine braking until I burp the throttle.


I spoke with my tranny guy, and he suggested and vrv regulator adjustment and then unplugged the modulator and see what happens. After a few tests, he suggested I try a govener spring and weight kit to see if I could "fine tune" the shifts.

I also have a marginally weak vacuum punp, so I plan to swap that out first and see the results of a stronger vacuum.
