    Downhill in lower gear with automatict ransmission

    I notice that the ATF temp goes up to ~200F when I get to the top (usually 140-150F on flat highways), it drops a little bit when I go downhill _regardless_ of whether I use the brakes or engine braking.

    Downhill in lower gear with automatict ransmission

    Thanks a lot for the responses. I have to regularly do a ~20 mins of steep descent, hence the question. If engine braking doesn't harm at all, I'll just do it <img src="/forums/graemlins/smile.gif" alt="smile" title="smile" height="15" width="15" /> If it harms only a little I'll use the brake.

    Downhill in lower gear with automatict ransmission

    I have a Toyota Camry with an automatic transmission with a shift knob to force the maximum gear, i.e. if I move it to 3rd, it'll only choose among gears 1, 2, 3, but not 4 or 5. When going downhill I can shift to one of the lower gears to slow down the car without using the brakes. Is it bad...

    "Partial" ATF change?

    Thanks all! It sounds great. It's an I4 2009 and has a dipstick to check ATF fluid.

    "Partial" ATF change?

    He is going to teach me how to do it myself... I don't know whether it's safe for the tranny.

    "Partial" ATF change?

    My friend/mechanic recommends me doing a "partial" ATF change, i.e. without pumping out all old fluid, hence maybe half or a third of the old fluid in the transmission would stay and be mixed with the new fluid. He himself do this to his car every 30K miles. Is it good/bad, what do you think...
