Re: TH400 - when is it supposed to shift gears

Hi
1st to 2nd is a quick shift to get you going
not sure on the shift points but the carb has a tab on the side of it to keep the 4 barrels from kicking in before it warmed up.this is a first mod when i get one(bend out of the way)
the kick down cable controls the downshifting.....need a pic or two the pass side of the carb and from the throttle cable drivers side to the back
