My future mother-in-law and her husband have just arrived to pick up their Toyota Mark 2, a RWD auto diesel that they left here two weeks ago when something electrical played up.

Mac (the husband) brought a car trailer, the kind that you drive one pair of wheels up, leaving the other pair on the ground.
Mac knows the car is RWD, but he's driven the front wheels onto this trailer, when I said it was RWD he said he didn't care if he wrecked the transmission, since it's damaged already.

I'm just worried that when the transmission siezes, it will lock the real wheels of the Mark 2 up and cause an accident.

Will this happen?

Mac's a diesel mechanic, but pretty rough, so if he says it'll be alright, I don't really know what to think.

 

As long as the car is in neutral it shouldn't hurt anymore than cruising.

 

what you do is take the driveshaft out.
unless you like broken tranny's, since the auto tranny wont pump fluid.
