Neutral towing

[RangerBill]

Thats a start, but its too vague...

What kind of electric motor.
What is the fail safe?

The fact that there is a clockwise and a counter clockwise motor is giving me hope.
I am thinking there is some kind of a worm drive there.

I have to dive into it, but this tells me there is hope.
It should be possible that once the tx is in N, if you cut power, it will remain there.
Obviously, this hasnt been proven yet, so we will see.

Thank you for providing the schematics.

I have a 2019 lariat that I tow behind our motorhome. Has anyone added an electric pump to circulate transmission fluid while towing? Or is this possible?
I’m not really a mechanic.
Sometimes we have an odor after towing, smells hot. I’m guessing from the transmission. On the last trip I did start the engine for a few minutes when we stopped but still had the odor when we got home. I figured someone here will know.

Yes you could possibly disconnect the connector on the motor but the circuit will see lost communication from its feedback sensors in the case motor for proper position (neutral)

This is what we need to verify.

It 'could' be that once you cut the battery power, it will remain in the state that it was in?

Maybe there is a way to build an adapter plate that has a mechanical override?
No idea yet, but happy to start digging into it.

I have unraveled shit like this a 1000 times before. Not guaranteeing anything here, but at the very least, I would like to fully understand how the system works.

The motor leads are shorted together when not being commanded to rotate. This will cause the motor to be harder to rotate by mechanical means. As long as the motor windings, relays and wiring are intact, this will make the motor less likely to turn when commanded off, and will cause the motor to quickly stop when power is removed due to the short applied by CW and CCW relays being de-energized.

Only one way to find out for sure!

Something tells me I'm gonna be the guinea pig here lol.

I went ahead and bought a transfer case to look into this a little bit.
Here is the thread that I created: https://www.ranger5g.com/forum/thre...-or-neutral-tow-thing-figured-out-here.42192/
