Should overdrive be off for towing with Jeep Grand Cherokee?

Answer 1

I tow an 18.5' Bayliner with a 2004 Grand Cherokee Freedom Edition 4x4 with a 4.7 H.O., tow pkg. and heavy duty cooling pkg. The boat is considerably under the rated tow capacity but I always turn off the overdrive especially going up and down hills. Jeep recommends to do so if you are towing and the overdrive is constantly kicking in and out; if you do not you will burn out the overdrive unit and transmission. Hope this helps.
