Exclamation

MB suggests that any MB car equipped with auto trans be towed on rear wheel for less than 30 miles at 30MPH or less!

You will need a replacement trans!

The noise is fried planetary, due to lack of lube oil

That's a lot of towing to do with stuff in the transmission spinning around with no lubrication. In the future, flatbed it if it needs to be towed.

planatery gears explode

the planatery gears on the input shaft look like a bomb exploded under them. destroyed every thing in front of the transmission. i will never use a 2 wheeled dolly again.

Really nothing wrong with them on the non-drive wheels.
