    I'm not sure, but I think I read a while back that driving in 4hi for extended periods of time would cook the tranny fluid. I am wondering if this is true or not, and looking for clarification. I tried searching, but couldn't really find anything. Thanks

    No, your not supposed to leave it in 4 hi for extended periods of time because you will ruin your transfer case because it doesnt have a differential

    for extended travel in snowy conditions you should be fine but, i have never really tested this theory out myself.

    i doubt you would hurt anything it also depends on what extended travel means to you a couple hundred miles may not be advisable though.

    Depends what you're driving on. If you're on mud or snow, no problem. If you're on pavement... why are you in 4WD?

    Well driving in mild conditions no it won't efect anything on mud/snow gravel. But if you were busting trail with tires a lil to tall for your gearing and were really working your tranny and heating it up it could. I always use low when theres major resistance from deep snow etc.

    I thought I had read that someone smoked their transmission fluid doing that but I probably misread it .

    It's easier to keep momentum going then to have to create it again from a stop.

    I'd much rather start in 4WD and if I get stuck, lock the rear. If you have a TRD Sport. Well, sorry. :eek:

    Im too lazy to keep moving the switch back and forth. Also if im in 4wd then I don't have to get stuck as much in the first place. Also I feel I paid for the 4wd so I should use it out pf principle. :)

    No way,
    I have driven literally hundreds of miles in snow and gravel with the truck in 4hi, with no issues. When the roads are shit here in Montana, i leave my truck in 4hi for months on end and run 70 down the freeway to and from works, for the last 3 years with no problem.
