One solution but not sure on reliability or compatibility with off road use.
Remco's Drive Shaft Coupling
Prevents automatic transmission damage to your rear axle drive vehicle. When you tow your rear axle drive car, van or pickup, the drive shaft to the rear axle must be disconnected to prevent damage to the automatic transmission. This requires mechanical service under the car which is not convenient for RV towing. Remco's Drive Shaft Couplings was developed to provide a quick and easy means of disconnecting the transmission while sitting in the driver's seat. The coupling (mechanical clutch) is installed into the rear portion of the car's drive shaft, near the rear axle.
When disconnected the rear axle is free to turn without turning the drive shaft or transmission. The coupling has a control cable attached to it which extends to a location under the driver's seat. This control is pulled out to disengage for towing and pushed into engage for driving the vehicle.

Remco's Lube Pump

When the vehicle is towed, this engine-driven pump does not operate. Another means of lubrication is needed.

To tow your vehicle, connect the cable and turn on the switch on the monitor in the motorhome and you are ready to go.

Full volume selector valve directs oil for driving or towing.
