The reason why you are not supposed to tow SVX (or any car with automatic transmission for that matter) is the lubrication of the gearbox. Normally transmission is lubricated via an oil pump, the pump is connected to transmission input shaft and only pumps when engine is running. If engine is not running, the pump is not working.
For short towing distances there is residual oil on clutches/gears, but it's not enough for long/fast tows.

Installing FWD fuse makes absolutely no difference while the car is being towed without ignition on/engine running.

If you lift front wheels of the ground, but not the rear ones, the transfer clutch gets to suffer - there is a lot of motion there and again not much lubrication. Hopefully this can be repaired by replacing just the transfer clutch without removing the whole transmission from the car.
