Wrecker towing automatic

Hi all,

Is it safe to tow our trucks from the front, rear wheels on the ground?
01 F250 4R100 4x4. 7.3.
Mine got hit yesterday and was towed about two miles to a nearby shop.
Driver seemed competent and I didn't think about it at the time.

Thanks.

Two miles shouldn't hurt it.

As Mark said, a few miles won't hurt. If you have a manual transfer case, you slip the lever into neutral and you're good to go. If you have ESOF, then long term towing may be an issue.

What will happen is the wheels turn, which will turn the output shaft of the transfer case and through that the transmission. Turning the transmission output without fluid circulating in the transmission will cause parts to turn into junk.

Thanks Mark and redford. I am concerned with later, will be moved 15 or so miles with freeway driving.
I know some trannys don't have any way to pump fluid if motor/front pump isn't turning.

15 miles at freeway speed would be a concern. Make sure that they drop your drive shaft, or insist that they utilize a flatbed.

If you look in your owner's manual I believe it states a maximum number of miles, and a maximum of 35 MPH with the rear wheels on the ground.

If they go above this expect to replace the transmission.

Very, very few automatics have a pump turned by the wheels. I only know of one offhand, it's a front wheel drive GM trans.

Just had mine towed and insisted on a flat bed so I didn't have to worry. They said no problem at triple A.

Just took an extra 15min to get the flatbed instead.
