The Disuster

Also because its hydraulically shifted and only has the 2 solenoids to put it into overdrive and lockup you can wire it manually to 2 toggle switches. Around town you leave em off. When you get onto the freeway and above 55, you turn them on. Instant lockup and O/D Below 55, you turn them off, it's back to a 3 speed. Any aftermarket 3 speed floor shifter with linkage brackets for A727 A904 will work on a 42RH 46RH. Your stock column shifter will also work. Even the transmission pans are the same as the 3 speed transmissions they evolved from. Your stock shifter lever off your A904 will fit right on the 42RH 46RH and it's in the same spot.
