Question about MFU shifting......

[Bill 832]

Hello again fellas! Still working on my Knight Hauler, going great, have most of the wiring done, and waiting for my body to come out of paint to finish wiring lights on the cab. Have the MFU, motorized trailer legs, and a Futaba T4YF-2.4 transmitter. The question is, (and I know I will feel like a tool after I get the probably simple answer) I have everything hooked up per the directions, and switched it after I read something on here about hooking up the MFU to the radio. Now my steering is on the throttle (which is notched), and everything works fine....EXCEPT that the gear shifting is still on a spring loaded lever, the left stick, and the tranny just stays in the middle gear. When I switch gears, it goes back to the middle gear. It seems like it would make sense to put it on the notched channel, also on the left stick, so it will stay in the gear you put it in, but that is not what anything I have read says. Am I missing something here? Thanks, and will post some pics soon.
