    Default Does this hurt the transmission?

    Does it hurt the transmission to shift into neutral to coast down, then shifting it back into gear. This is the first automatic I've owned, I'd coast down with my manual cars all the time. If I just lift off the gas, the trans will drag me down so that I will slow down faster than I want.

    I tried it on the way to and from work (22mi one way) and managed to get the mileage computer up to 19MPG.

    Should not hurt the transmission. You could also flip it in to manual mode and up shift. If your foot is not on the throttle you are not using that much fuel.

    It is bad for the transmission. When you put it in neutrail it stops pumping much needed oil to the vital parts of the transmission.

    Just be careful and don't go into R....that might make a lot of noise. Personally I don't think it's a good idea to coast down hills, but to each his own.......

    Automatic transmissions does not work the same way as manual transmissions. Automatic transmissions use pressure plates using oils to help change gears. By constantly putting the automatic transmissions into neutral your just making your transmissions work harder.

    I would advise that you not do that while driving around.

    Actually against the law in CA to coast down hills. Vehicle needs to be under power at all times.

    Not as long as the motor is running it won't necessaraly (sp) huurt anything in the short term, the pump is driven by the torque converter that is connected to the flywheel, connected to the crankshaft. It could eventually effect the torque converter and also the drums/pistons/clutch packs for the gear it is being put back into coming out of neutral

    Thanks for the info....but I try to stay away from that State as much as possible. Too many people and too many weird laws...plus I can't carry my S&W there either.

    It's possible that the electronics controlling the trans will not let you shift into reverse at that speed, but I don't know.

    Just an FYI to take it for what it is worth.

    The manual says specifically, in a yellow box, in bold print, not to ever do that.

    Take this man's good advice. If you want your tranny to last, drive the automatic like it was designed to be driven.

    Besides, so you got 1 mpg better. After 100,000 miles, at 18 vs 19 MPG, that'll save you 292 gallons. Is it really worth the hassle to save that much gas over the course of 100,000 miles. Not at all.

    dangerous, always should have the truck under power. your not saving any gas anyway, i get 99.9 mpg going down hill under no load at speed, according to the readout. your doing needless shifting and just putting more strain on your nice expensive transmission. stop now.
