Tow/Haul button

It locks you out of overdrive to prevent overstressing the transmission.

In laymens terms, can I still drive 55mph, and how will it affect my handling and mpg?

Handling? No impact.

MPG? It will drop substantially, as noise and wear on drive-line (engine mostly) will increase.

In layman's terms..... "maybe" on the 55 and handling. And "definitley" on the mpg. It all "depends" on your trailer's size, overall weight, tongue weight, and wind resistance. The larger and heavier your trailer, the more mph, mpg, and handling will be negatively affected. If "fish tailing" (sorry for the technical term) becomes a problem, then increasing tongue weight can help (by shifting load weight forward or moving the axles(s) backward) but don't put so much tongue weight on the hitch that it lifts your front tires off the ground (thereby affecting handling). Also, you may want to test your "backing up" skills if you've never backed a trailer before. Good luck :-) HeBeJeepN '99 XJ Sport, Selec-Trac, Trac-Lok

Your gas mileage will probably be better than if you tried to tow in OD plus you'll not cause as much heat build up in the trans which is more detrimental that running without OD.

Before there were OD transmissions, there were manuals and automatics that didn't have OD that held up for hundreds of thousands of miles in car, truck and towing situations ... most didn't even have a lock-up converter.

Generally, all you needed was a bigger trans cooler, which I recommend anyway on all automatics.

I'd recommend he go slowly and carefully when backing up with a trailer, even a small one.
