What ratchet shifter are you using with a 518 46RE ?

I used adjustable pressure switches to tell the OD and lockup when to apply, and it can do this because the governor in the RH series knows what the road speed is.
1-2-3 are normal like a 904 then governor pressure activates OD at 55mph and lockup at 75mph. (because the switches are adjusted to activate at each of those speeds automatically)
I can deactivate that by turning both switches off, and the trans acts like a normal 904 3 speed.
Or I can turn off OD only, or lockup only and it will shift 1-2-3-OD at 55mph or 1-2-3-lockup at 75 mph.
Then of course with the ratchet shifter I can manually shift 1-2-3 and then switch on OD at whatever speed I want manually as long as I am over 55mph.
Same with lockup but I have to be over 75mph for it to engage.
