    How often do you change your trucks Transmission fluids being that you are towing a trailer?

    My truck I bought new and currently has 17,000 miles on it. Wasn't sure if it's time to do anything to the trans or not.. Thanks,

    I change mine once a year. My brother in law is a mechanic and says its fine . Good enough for me but if you have a new truck you may want to consult your dealer to make sure it satisfies your warranty.

    youre in jersey i don't know if you plow...


    i definately consider usage over miles. even in tranny fluid, and obviously in oil. tranny, at least at 25 000 kilometres, and less if say a winter was bad. thats reg. for us, not synthetic.

    oil we use hours of use, i've done changes at 1200 km, synthetic oil.

    fluid and filter once a year. Even with that there is still a few quarts that stay in the converter.

    I would love to change to all synthetic but I cant find a quick lube place that can do it.

    every six thousand miles. the place where we get oil changes only charges us $20. he has one of those vampire machines, where it circulates new fluid in and old fluid out.
     
  7. We do a tranmission flush twice a year on work trucks .Spring before season starts and again around september.Trans flush gets all the old fluid out and all new back in

    Try to find a small locally owned shop to do your changes. Where I take mine I bring my oil and filter and they change it for $10. That is the engine oil on my PSD. Dunno what a trans would run. I have a manual and changed that myself. Granted I do all my tire biz there and most other work. I have known the manager there for over 7 years.
    And I run Amsoil front to back.

    I'd certainly recommend a good synthetic in the transmission of a work truck. Like Brickman, I run Amsoil front to back in my Dodge. I gained a little fuel mileage when I completely switched over, can comfortably run a little longer between changes, and am confident that the lubed parts will last that much longer. It does cost more, but I think it's worth it.
    As far as how often, use the severe schedule in your owner's manual with conventional, and the regular schedule with synthetic would be my recommendation.

    I also go for the once a year transmission fluid change. I run dinno oil in the engine but synthetic in the transmission and differentials.
