can an 82 SD be moved with a tow dolly
I read somewhere that an 82SD can be towed on a dolly with the front wheels on the dolly and the rear wheels on the road. The thinking was that the rear wheels would drive the rear transmission pump.
I'm going to look at a car tomorrow and will have to rent some kind of trailer. My 1st choice will be a U-haul flat bed but I'll take a dolly if the flat bed is not available. I don't really like U-haul but that's my best shot at a trailer. Distance is about 50 mi mostly interstate speeds which in Nashville means at least 70 to keep from getting run over.

if you plan to drive on the highway you have to either have a car trailer or disconnect the driveshaft.
biggest problem with disconnecting the driveshaft is that the flex disc and or center nut can be stuck. But you can tow your automatic benz with a tow dolly without disconnecting the driveshaft: up to 75 miles and no faster than 30mph (from owners manual) one time I towed my benz with the rear axle on the dolly but I don't recommend it because I had to drive at no faster than 45mph because anything faster than that and it would start swaying dangerously. I drove like that 60 miles on the interstate an no cop paid any attention to me surprisingly Last edited by Usaguy; 08-28-2019 at 06:44 PM.

Hopefully you have at least a 3/4 ton truck to offset the trailer weight?

I don't know what years are involved but the later transmissions like my 84 300D has 2 pumps in it so it can be towed at a the reduced speed mentioned. Don't know about the earlier Transmissions with a single pump.
http://www.europeantransmissions.com/Application.htm The above site shows an 82 SD as having a 722.303 W4A040 transmission. Does anyone know if you can Tie the Steering wheel to keep it from rotating and us the Tow Dolly on the Rear Wheels and pull the car from the rear?

I'll figure a way to flat bed or drive it. I dropped the drive shaft on the road 1 time and it is more trouble than finding a trailer.
That was the trip where I bought the Cummins. Fuel filter was stopped up on the SD but I'd just gotten the it and couldn't diagnose and web access wasn't available.

why tie the steering if when you remove the key the steering locks itself. as mentioned in my #2 post I don't recommend it

Some people swear by towing nose-down but I've tried it twice and it's always fishtail city above 45-50 MPH. However, when the driveshaft was difficult I've had luck disconnecting the CV axles from the hubs and zip-tying them up out of the way. Not sure if the space under a w126 will allow this but it's worth considering.

One of the problems with towing backwards is what used to be toe in for stability, becomes toe out. With caster being there to self center the steering when going forward, going backwards will randomly try to make the wheels steer from one side to the other even with the wheel tied. ( think free play in the steering system. )

I towed an 82 300D on a tow dolly from Asheville NC to Knoxville TN, about 150 miles to my house from where the car was.
I had no other way to get the car home, so I let er rip. Put the car in neutral, strapped it down and headed home. Towed with a 01 F150, we averaged around 60ish on the highways. When I got to my driveway, I hopped in the car and figured I'd roll it off the trailer and deal with the melted transmission later. To my surprise the car was at operating temperature, Obviously the rear pump was pumping fluid through the cooler, and the radiator had lots of air flowing across it. The transmission shifted just fine. Wouldn't recommend it, probably wouldn't do it again. At the very least I'd use my cummins to tow now. That f150 was sketchy as anything to tow with.

Neutral in an automatic transmission really isn't neutral and back driving the output shaft can cause the planetary gear train to spin to ludicrous speed. ( and no I don't mean the rapper ) This effect varies from transmission to transmission but think about driving in 1st gear at 60 MPH or more. I've repaired automatic transmissions where the driver thought that coasting down hills in neutral with the engine on or off would save $. It does not as the long term as evidenced by failed planetary needle bearings in an otherwise excellent condition transmission.
