Chevy Truck
can I run modulator valve on a 1984 thinking 400 trans modulator sets in very back of tranny detent cable broke can I just block off n if and what would be required to make shift.Helps get into "passing gear" when needed.
you can block detent and use mod valve and it will work like normal, except 3-2 downshifts may require much more throttle than normal. OR you can just move the shifter down a position if you need passing gear.
