46re

46re has the electric valve body. It has a 8 Pin plug down on the driver side of the transmission. I don't think that's what you want.
The 46rh has a hydraulic control valve body. It should have a 3-pin connection down on the side of the transmission. This is the one you want.
This is the one that you put the two toggle switches in the vehicle and you can turn the overdrive and the lock up on and off with.
