Yes. Definitely remove the driveshaft and plug the rear seal opening.

The GM auto's all have a pump driven by the torque converter and you stand to have a seal and bushing failure from no lubrication as the output shaft turns for thousands and thousands of times.

Pull the drive shaft for the trip or rent a uhaul trailer.

 thanks for the explanation.. I know Power glides pump from the output , hence the can be push started..   just knew it was bad with any Auto to pull over a long distance spinning the driveshaft.

 

I pulled an old 1/2 ton for an hour once,  but it ran so I left the engine idling , while I towed it in neutral,  worked OK..

Decades ago I towed cars with a custom tow bar, probably 35 times (Chevelle/Beaumont/Corvair's mostly).

- if it was only several miles, I often let the motors idle in the neutral gear

- over long distance (like 2 hours), removing the drive shaft is a must...or the transmission will overheat and all the oil will leak out

5 years ago I borrowed a car dolly to tow a 1996 Jeep Cherokee (RWD, originally a Florida vehicle purchased in Ontario).

- I backed the SUV onto the car dolly, so the back wheels and drive shaft would not turn, being elevated off the road way

- next roped off the steering wheel (through both door handles), maintaining a straight steering wheel position (fixed front wheels now trailing on the rear of the tow rig)

^^^^ Towed the 2 wheel drive Jeep for 2 hours straight, without any problem (drive train remained perfect).
