Diesel Dog,

But every time you take your foot off the accelerator, the torque is reversed with much more force on the gears than the small friction drag causes when towing.

I suppose it is possible as Brad says that the rear bearing could be damaged by lack of lubrication when towing, but I never heard of it happening. I towed my 190D about 800 miles with no noticeable damage.

If you need a 190D transmission I have one for sale.
