46rh od and LU wiring

[mbaird]

Which of the 3 pins on the trany is LU and which is OD ?
I have found diagrams but they don’t indicate the orientation of the plug … is the pin closest to the front the lockup ?


Thanks

46RH connections

Looks like lockup is toward the front and OD is the rear pin.

Thanks .. it’s hard to tell if that diagram is from top down or bottom up. Just want to make sure before soldering and assembling the plug .

Oh I gotcha. Yeah, that is confusing. How's this: A518 Lock Up Wiring Instructions (46RH Only)

I have found several different techniques for controlling the OD and LU . One uses 2 pressure switches and another uses one . I chose to go the simpler route using 1 switch and 2 timers . But I also read that it might be bad to have both disengage simultaneously? Why is that a problem?

Here is the diagram I am using

Imagine you have 4:10 gears.
This is fine on the hiway with OD and lockup but,,,what happens when both disengage?
ZING!!!

True but that would be an extreme example. I suppose if your doing 80 and floor it enough to drop to 3rd there would be a significant rpm spike but I don’t see myself doing that.
Funny thing is that is exactly what my 2003 Ram does . I hate the programming on that trany ! It will bog when I accelerate at hiway speeds until the pedal is almost floored ! Then it disengages the LU and OD while simultaneously downshifting all the way to third . Then it quickly starts shifting up , re-engaging od , then lockup then starts to bog again .
Climbing mtn passes or even moderate uphill are so annoying!

I intentionally did not install the throttle disengage for that exact reason.
It takes a very steep grade for that to be needed in the car.
If I need to accelerate that hard I just turn OD/and or lockup manually, then set it back to fully automatic after.

I guess I am asking if it could damage the transmission ? Or just over rev the engine ?
