Quote: i REALLY wanted to keep my slapstick, but trans builder talked me out of fmvb (since i'll have considerably more horsepower than stock) because he told me rmvb allows higher line pressure (or something to that effect) than fmvb......i will install the Duncan shift-r-gate, so at least i can still keep my slapstick though, haven't tried it out yet though.
This is confusing, because no matter where 1st is on the shifter it still in the same spot in the transmission. and i dont see how horsepower would make a difference in shift forward or backwards.
Did you see this ?
Quote: This is because the forward pattern uses the shift valves to command the shifts by short circuiting the governor passage. The reverse pattern shifts directly from the manual valve, eliminating the shift valves, giving a better quality gear shift. Shifting through the 1-2, 2-3 shift valves can limit the line pressure because they influence shift timing. Allan G.
The more power an engine makes more line pressure is needed to hold the clutches from slipping.
