How Much Wear from shifting into 4x4 Low?

    So basically in wondering if it hurts the transfer case or transmission in any way by shifting from 2wd, to 4 hi, to 4lo a lot? This may sound like a stupid question but I just thought it may wear certain parts out? Maybe I'm crazy? I'd really like to do a lot of plowing in 4lo this year as my transmission doesn't appear to be 100%, and I'm wondering if there are any cons from shifting in and out of all those gears so many times during the night.

    Obviously I wouldn't shift it out of 4lo if I'm just driving down the street but from one side of town to another to another can mean a lot of changes in the TCase. Any thoughts? Thanks guys

    Generally 4hi is ok up to X speed. I usually try not to go any faster then 15. I have tried faster but it won't engage.
    4 low. You cannot shift it while moving period. Complete stop, engage, resume.
    What trk is this your speaking of?

    If you're trans is weak why not have the problem fixed now instead of having it go out during a storm?

    It's a 99 F350 7.3. I wouldn't say it's weak, it just does weird things like if I get on the throttle too early when shifting into R or D. It's shifts perfect and otherwise is great. I just have to be mindful. And I know very few guys of you use 4lo, I just figured it would cut down on stress.

    I generally plow in 4 high but do use 4 low if the snow is deep, wet and heavy. When shifting out of or into 4 high i'm either stopped or barely moving but that has always been a habit of mine and if i'm only going a short distance through the snow I leave it in 4high. I've never felt comfortable about "shift on the fly"...emphasis on "fly". It might not hurt to have your tranny flushed and a new filter installed... might prevent weirder things from happening in the middle of the night in the middle of a storm.

    I don't own any automatic's but I know enough to know if I felt if there was weird things going on I'd have it looked into.

    If you get on the gas while it's in the pause stage of shifting into any gear it will slip badly. Put it in park and actually wait for it to go into gear and not be in a hurry and it's perfect. I most certainly won't be shifting into 4 lo on the fly haha

    i have never used 4 low except to see if it works when buying the truck.
    if your trans is acting funky get the fluid and filter changed . it should be done every 30 to 35 thousand miles.

    And if I don't trust the local ford dealership... Guess I'll go buy the 20 quarts of ATF needed and the filter and do it myself

    If you leave it in manual first, and low, your top speed will be like 3 mphs

    I wouldn't recommend 4 lo on pavement. You'll were out more than just a trans.

    A fluid and filter is just wasted money. Either get it repaired now, or sell/trade now. Trust me here.
