Towing

We're leaving to travel 440 miles to pick up my daughter a 2000 Toyota Celica GT-S with a U-Haul car dolly trailer.

I'm wondering if I need to have the OD off when pulling this vehicle with my 1996 GC 5.2L?

A resounding YES!!

And remember every time you turn off the ignition it resets that switch. So you will have to push it again each time you stop for fuel/potty/food.

Why the need to turn OD off?


Is this for whenever you tow? I tow frequently too, so wondering as I have never heard of this OD off requirement.

It changes the shift points, putting less strain in the engine, for one reason.
It's Ok to have on, once you reach your cruising speed on level ground. I turn mine off in that case....but hit the button again when coming to a hill or bridge, while towing. Same goes for stops.

Sorry I got back so late it's been a busy weekend.

Thanks for the information. I changed the oil, checked tire pressures, put fresh gear lube in the axles, and changed the tranny fluid, plus checking levels on everything else. It should be a successful trip.

You will burn it out towing with it. It's rather weak.

Your profile lists Green Bay which suggests you won't be towing over the Rockies or Appalachians. I tow a lot with my 5.2 ZJ including pulling a trailer of similar weight coast-to-coast. Put on 10,000 miles on that trip. The trip included hundreds of miles of 70-75 mph freeway all the way to back-road passes so steep I couldn't maintain speed in 3rd gear. I also tow trailers in the Cascades many times a year. 160,000 miles on vehicle and not a stitch of trouble with the driveline. It does have the factory tow package.

All that being said, on level ground I let OD operate normally, keeps the engine RPM down and helps the gas mileage. If I get in the mountains I disable the OD to improve performance and reduce shifting.

Drive safe and leave extra margin for braking -

Thanks GB. It will be a fun trip. We're going to Toledo, OIIIIIIIO where approximately 100 of my relatives live. It will be a fun filled weekend.

This exactly.

ZXJ isn't a 1-ton truck, and it's downsides are on the bad brakes and lack of aux tranny cooler in many of them. Other than that, they are actually pretty damn capable tow trucks.

I just got this ZJ at the beginning of this year and it appears to have been taken care of very well. The brakes could be better but I trust it to make the trip and I just thought it would be smart of me to ask around to make sure I don't blow the engine/tranny on the way back.

The last ZJ we had for 11 years and she ran strong the entire time we owned her, 1997 I6. Multiple high mileage trips and towing various loads short distances with OD off. It proved quite capable.

In city driving, under 40mph, when I switch the OD off I smell a light burning stinky smell when I get out of the jeep. Trailer is not attached.

Transmission, all differentials and transfer case were recently serviced.

Could be residual fluids burning off the various parts or exhaust.

We made it back in great condition. The only problem I had was with U-haul giving me an auto transport trailer instead of the tow dolly.

We had a great visit with my relatives down there and we got 20.5 MPG on the way down and 14.5 on the return trip. I forgot how comfortable the seats are on long trips.

THANKS for all the great information and THANKS JEEP for the great truck ! ! !
