    Noticed today on the way to work that my Auto tranny downshifted hard enough to run the rpms up to 3000 from around 1200rpm. Had foot off accelerator and was going for some brake. Was running around 30 mph. I thought it did this the other day but wasn't paying close attention and snubbed it off. <700miles on vehicle. Anyone with same experience or some knowledge on the matter.:confused:

    I haven't quit figured it out yet... but on certain occassions when you're coasting (so to speak) and you step on the brake, it does downshift farther and seems to help with engine braking. If you're not expecting it - it tends to pitch your body forward abit from the downshift.

    I think it's pretty normal.

    I wish I could figure out how to make it do it whenever I wanted it to....

    My truck is doing it too. (Yet another reason I hate auto, I really wanted a 6MT but getting a deal on an '08 sacrifices had to be made.) The entire time I'm decelerating it'll continue to downshift causing a lurch (although TBH I don't mind it doing this). It's the first auto I've ever driven that downshifts while cruising or lightly braking to a stop. From what I've gathered, it does retain a driving habit memory (for lack of a better term), so it's possible it's memorized that on occasion I force it to downshift (either for fun or to limit brake usage). Add in the fact I've been driving it like I stole it since around 1500 miles (just broke 3k now)... lol.

    One thing I have been experimenting with, since it "learns" your diveing habbits, is to shift it manually for a while. I did this during my daily rutine and now it seems to shift just how I would want it to. :)

    Thanks for the input everyone...I feel better now.

    I've trained a few birddogs, so how hard could it be to train a Taco!?!? Thanks Chris, great info...Just left a 5 spd Accord that I've been shifting for 10 yrs. Whats another few months of shifting going to hurt????? Thanks:thumbsup:

    Dont have to shift it that long. Maybe a day. When you go to work, and run an erand, shift it manually like you would want it to shift. I shift mine manually only once in a while. Maybe 2 months or so, just to keep it on its toes. :D And then, only when, say for example, comming to a slow freeway on ramp.

    I love the passion everyone has for their Tacos. Its starting to grow on me. I'm refering to the phrase,'keep it on its toes'. Thats awesome!:DOf all the new vehicles I have bought, this is the best I've ever owned so far! Thanks for the help Chris, I'll start training him on my way home.:cool:
