F53 transcomand location

Maybe a little off of the original subject; has anyone found a way to control all of the gears on the new 6 Speed Transmission used on the F53 Chassis? My Pusher motorhome had the Alison 6 speed Transmission and a controller that allowed my to lock or hold any of the specific gears. I would really like the same type of control in my motorhome. JH

My is drill into the Motor home frame just above the tans.. Not on the vehicle frame.

Thanks guys their directions specifically say not to mount to the frame so that’s why I was asking. Did you guys drill holes into the frame to mount them?

My transcommand has been on mine for the last 17 years it's mounted on the inside of the frame rail just next to where the wiring is for the trans.

direct above attached to frame. My cable did not have a long cable.
