    Yep, that's what I was going to say.

    Downshift your auto if you want the engine to hold you back more. Don't bother messing with it for going up a hill.

    Really I should take a picture of all the carnage that happens around here on these hills. People try driving up them in overdrive and end up literally burning there truck up. There has to be one a week smoldering on the side of the road here. If it's hunting and will not stay in the high gear it's time to shift down.

    In the situation you describe, I let the computer/transmission shift to 4th, then manually shift to 4...no pedal manipulation.

    after about a year of trying i've gotten really good at double clutch downshifting while braking. i can row down 2 gears smoothly in about 3 seconds. and go down into 2nd (accpetably) on a regular basis. but its not completely smooth, the car often does give me a lazy bog down or kick in the butt, you do know it happenned but you also know the car didnt slow down but somewhere in a mph, its more of an embarassement that lasts a fraction of a second.
    the question being that if you don't feel like you have given your syncros much work, you dont really hear them whir up as a result of your actions. And you barely feel more than a gentle tug (or at worse a small jerk) from your rev matching. Am I screwing my car up from doing this day in and day out?
    I mean, i can understand how you can find yourself paying out of pocket really quick if you routinely mismatch by 600 rpms on a daily basis. but the case of really small but visible mismatchings raises nothing but questions for me. do i suck badly? is it absolutely necessary to be 100% perfect in this game or get out? Ive been learning without a tach and i had to make a wooden pedal raiser btw. /watch?v=klMur6TPkrM i wish my taco were free revving

    You don't want the trans to hunt in O/D so lock it out if it is other then that (except maybe going down hill) let it do it's thing Toyota spent a lot of money designing the system to give the best results.

    http://www.youtube.com/watch?v=Xo66wjiDneQ first i listen to this music.
    and then i do the whole process. brake in, clutch in shift to neutral, clutch out, rev up, clutch in shift into next lowest gear, clutch out. it is a sub second process. for some reason, in a porsche, the thing doesnt fight you. porsches are very forgiving with this business. but my tacoma is not. i heard a mechanic say that its almost as if it actively fights your downshifting. I interpretted this as 'you have to get really good really quick, and i did. but now ive come up against a wall, and i guess only practice will make it completely smooth. my concern is if im being wreckless and irresponsible with even little under revs unintentionally being made on a daily basis. im concerned that im really gonna pay and pay within a year or two for my bad technique. Im wondering if these fears are unfounded.

    This you see is why God put synchronizers in standard transmissions so we don't have to do this.

    Dude. With all due respect - you don't need to double clutch a synchronized transmission unless you really want to.

    Yes, you must rev match your upshifts.

    1. clutch in
    2. blip the gas pedal - about 1000 rpms worth depending on the gear you're in, and just a tiny bit *above* the speed for the new gear.
    3. shift the gearshift lever to the new gear
    4. clutch out - while easing off on the gas to match final engine speed to vehicle speed.
    Piece of cake. :)

    And - all that being said -- you added your reply to a poll that applies to automatic transmissions - causing a natural increase in the sarcastic responses you're seeing. :rolleyes: :D
