| + | You must install a full set of returns springs in the direct drum. Ignore the experts or online information to leave springs out of the direct drum. If you have a set of heavy duty return springs from a kit or supplier, install half HD springs with half OEM springs. This helps to avoid residual oil behind the piston from forcing the piston out at high RPM when in 1st or 2nd gears | ||
