Thread: tranny temps

  1. #1

    Default tranny temps

    So I just drove a little over 1200 miles in two days from Alabama to Colorado and I noticed my tranny temp got up to 170+, I thought this was kinda high and have noticed that during normal driving around town my tranny is getting up to the 180's does this sound right or should it be lower. Also does anyone know if there is any tuning I should do to my truck up here in the mile high area of colorado, it does seem to suffer a little in the high altitude, I'm thinking it needs a less restrictive air intake..
    thanks in advance for any advice

    Not a transmission expert but I'm quite sure 170-180 is perfectly fine. Maybe Jimmie will chime in. Is your sender before or after the cooler?
    When you hear hoofbeats, look for horses not zebras.

    Those temps are normal. Remember the fluid is going through the radiator and your cooler is really a heat exchanger. So your radiator will warm your transmission fluid as well as cool it.

    You truck is getting hypoxia at altitude as do most normally aspirated engines. It needs more air! <G>

    Apologies for misspelling your name Jimmiee. I've done it a few times now. I'll get it after a while.

    180 is about optimal operating temps. Anything above 230 is way too hot and it's time for a trans cooler.
