O/D usage
I was under the impression that O/D should be used only at highway
speeds and for normal city driving you should drive with the O/D Off. It seems that `05 Explorer's normal condition, when it is started, is to have the O/D On. Suggesting that it is O.K. to have O/D on all the time. Is it? Should I be turning it off for normal city driving, or does it really make a difference? |

According to the Owner's Guide you should turn off the overdrive when driving conditions cause excessive shifting from O/D to other gears. Examples: city traffic, hilly terrain, heavy loads, trailer towing and when engine braking is required. When descending a hill, use the same gear you would use to climb up the hill and do not descend the hill with the transmission in neutral. Disengage overdrive or manually shift to a lower gear. If you don't have a manual, go to http://www.genuineservice.com/genuin...efault?page=E4 and downlaod one. Persoanlly, I only turn my OD off when towing. I have never had a problem with excessive shifting in town. Ed |

Ed,
Thaks for the info. My Explorer doesn't seem to shift too much in town, but I will check out the manual to make sure. -Jason On Oct 16, 9:52 am, "C. E.

There is virtually never a need to turn the OD off in any normal driving unless you are pulling/carrying a very heavy load or need the engine braking going downhill. |

O/D usage
someone told me once that towing with O/D on is very hard on the
transmission, I suppose the gear that is engaged with O/D. whenever I tow my boat, I don't use O/D. "Holmbrew" > wrote in message oups.com...

If you rely on engine braking you always have the same amount of braking whether that's the amount you need or not. I'm sure you have tried my way too and didn't like it. |

In OD around town it's always shifting, hunting for gears and the torque converter locks and unlocks constantly. It drives great, shifts smooth and at the right time with the OD off. I've heard with this transmission it's advisable not to use OD around town, but don't know if that's true. It would seem so to me, it shifts less and more smoothly with OD off. |

O/D usage
I've had 2 Explorers now, a '94 and an '05. I usually drive in O/D even
when around town. But as mentioned before, I usually pop it out of O/D when towing. Except on nice flat or slightly downhill on the freeway. I used to tow a lot with my old '94. But the gears were spread pretty far apart, i.e. 3rd always seemed to rev pretty high. Plus back then I used to drive way too fast when towing, so I frequently left it in O/D (I've since slowed down!). But the great thing about our '05 is the 5 speed O/D. Fourth gear can still tow nicely on the freeway without seeming like it's revving too high. The closer gear ratio is really nice! Of course, my wife is the primary driver of our rig, and she just shifts into D (O/D on)! One thing to be aware of (especially for you '94 era Explorer owners - not sure if it's true of the newer rigs) is to change your tranny fluid frequently if you tow often. I've read that the fluid should be changed every 12,000 miles when towing frequently. I used to change ours at about every 24,000 miles. No tranny problems after 120,000 miles. Many of my friends used to tell me that their transmissions dropped right around 70,000 with no service.
