Use Over-Drive??
Hi guys, I have a 1990 Bronco. I was wondering if you should or shouldn't use Over-Drive in low speed off-road situations. Which option is easier on the truck. ALso which option makes more torque?
THANKS A BUNCH!!!!!

Use Over-Drive??
Hi-
Lugging the engine in OD is bad, bad, bad for the transmission. Overdrive is for long highway cruises on relatively flat roads at high speed. The tranny might think it wants overdrive one second, then downshift the next. When it does this leave it out of overdrive and go in D. Example on the highway at around 50 in OD my truck seems happy, but any throttle will make it downshift out. In this case it's better just to leave it in D until you're doing a steady 60-70. In otherwords leave overdrive for a trip where it doesn't need to jump back and forth for the gearing of drive, and if it actually does go into fourth(OD) offroad then keep the shifter in D, overdrive's not for the trails.
