What does OD mean on Jeep?
hi, what does o/d off mean? It means your tranny won’t shift to the highest (overdrive; meaning taller than 1:1 gearing) gear. As adviced use the O/D off button when towing a heavy trailer or on extreme hills etc. to prevent the tranny from hunting between the highest two gears and to prevent tranny from overheating.
