Google Remco, the towing experts.
Enter your vehicle's information. The answer will be given whether it's towable 4 wheel down or not and what solution or options are available. For example: tow dolly, lube pump, or lockout.
Over twenty plus years of RVing, I've towed 4 different vehicles, all using Remco's lube pump. Had to replace a few lube pump parts (things do wear out), but have never encountered a problem with tow vehicle's transmission.
Try to avoid dollies. Too much trouble to load/unload.
