I had no trouble in 20 years towing with a 4R100 Ford trans behind a 7.3. I drove it 178 k miles before selling it. It had a trans cooler and trans temp gauge. I changed the fluid and watched the temp. Once in awhile towing a trailer I would pull over on steep grades like near Death Valley to let the drivetrain cool off, same with the brakes. the only thing I did not like about was only 4 speeds.

The 68RFE has 6 speeds which are easily controlled with the paddle shifters. The tow/haul is really good. I like it just fine and it much better than the Ford.
