    I just changed the tranny filters on the wife"s Durango. You use RTV instead of a gasket. Just wondering how long I should wait to put the tranny fluid back in. As always, thanks all.

    It doesn't say on the tube ??

    I always thought the general rule of thumb to be safe was 24 hours.

    I like to let RTV cure overnight (and I usually use the DOW 732 industrial stuff) but you could probably go ahead and refill the fluid and drive it in the morning...

    YMMV...

    :cool:

    Nope, just said cures in an hour and dry in 24 hrs. But I wasn't sure when it was safe to put the fluid back in. Most cases you don't have a full 24 hrs of down time. Guess I will put it off till the wife has to go to work tomorrow evening. Thanks guys.

    I AM ILK
    for front covers, oil pans and intakes(ie replacing a cam) when i have the motor buttoned up its getting fluids and is gonna be started. figure the intake with the front and back bead is the last use on a cam swap. and once i let the rtv setup i would say it takes about an hour to an hour and a half to get the intake, carb, fuel lines, coolant hoses, oil in the motor and anything else i forgot. i havent had any leak because of not curing long enough.

    so 1.5 hr.

    Yeah,things dont sit in shops for a day before getting filled and started.Ive always done it within the hour.Usually as long as it took to get things back together and get done.

    We have filled trannys up with-in 1/2 hour after using RTV and have never had a problem. Just make sure everything is CLEAN.
