    I just recently leased a 2019 tundra 5.7l and put a few miles on it now. When I wanted to test the acceleration after break in at 3500 miles, the first gear only revs up to 5000rpm before shifting into second then the rest at redline, why does it do this, and yes I'm used to the hard first to second shift on toyotas, I know toyota transmissions do that, but they also usually shifted at redline.

    Maybe it's to keep drivers from over revving things and damaging them. This scenario make me reflect on "back-in-the-old-days" when some trucks had a "granny gear" and a majority of the time the driver would start out in 2nd gear. The only time 1st (sometimes labeled "L") was used was on a steep hill or when loaded/towing. You would never rev the engine while in 1st/L, it was just to get you moving and to the next gear where you'd actually pick up speed. With such a low final drive ratio (4.30:1) in a vast majority of the Tundras, maybe the engineers deemed that it was best to have the transmission start in 1st just to get moving and then quickly shift to second. It's probably more economical too. I know that my truck is usually out of first and to second before I've moved much more than a vehicle length or two. Fist and second ratios are pretty close together as well, if the engine revved to redline in first, it'll probably be though most of the range of second too, not sure though. Personally I can't visualize there being any acceleration advantage by having it redline in first.

    Crazy acceleration from the v8 lifts your foot off the gas pedal. Don't skip leg day

    Were you in 4WD? For some reason I remembered reading about a lower first gear redline shift in 4WD - I think it was in the Ovtuned thread.

    You may need to trade the Tundra for a Supra! :D

    Naw I like trucks and SUVs, I just wish Toyota built like an "SS" tacoma, 4runner, or tundra like chevy and dodge do, with more added power

    The programmed shift points are awful. Worse than shifting "up" too quickly in my opinion though, is the shifting "down" too quickly, every time you let up on the gas. Kills the mileage.

    Some of this will get better as the computer learns your driving habits. (The drivability part, not the mileage. The later might get worse. When my truck was new, I regularly got over 20 mph and up to 25 at times, but now I'm settled into 14 like most people unless I actively and concientiously fight the trottle/gear relationship.)

    For a normal, pure accelleration feel with slower shift points, you can use beast mode: tow/haul mode "on," followed by two long holds on the traction control button.

    The sequential shift mode (shifter in left gate) could SORT of work to do what you want too. Though it isn't a true gear selector, it does resrict the highest gear to whatever you've selected.

    Idk why its like that, most likely for engine safety, but I think it gets fixed with the OV Tune. I could be wrong but read that thread and it does get discussed.

    I wish I didn't have to tune it the way I want it, but I guess that's why Toyota has these beasts running millions of miles

    Because Toyota chooses to aim for reliability by using 'tried and true' transmission designs, using planetary gears in tundra's case.

    Planetary geared transmission really require they get out of 1st gear as quickly as possible to minimize potential issues with the speeds involved of the 1st gear. So you'll notice all Toyota's with a planetary geared trans quickly perform the 1-2 shift and hold it no longer than necessary. So the 2nd gear will be a little lower to make up and continue the forceful acceleration you want while minimizing potential damage.

    It still accelerated plenty fast, No?
