    I recently purchased a 2012 prerunner SR5. I purchased it certified used with only 20k miles on it. I noticed that the transmission at any speed seems to piggy back on the engine and I start to slow speed at a fast rate. It also appears that the truck doesn't shift properly or at theproper rpm. When i accelerate it doesn't take off right away either... It feels delayed. I hope that makes sense. Anyways I want to take it back to the dealer but before I go back at least have a direction to point. Thanks for your help

    Its under warrany just take it to the dealer and tell them what its doing. The direction to point is poor shifting

    What do u mean "piggy back on the engine"?

    These trucks have passive engine braking......let off the gas, and unlike most autos, it starts to slow itself.

    Also the transmission is supposed to "learn" driving habits......I don't know if u can zero it out by disconnecting the battery for 30 minutes or not :(

    I know it was odd to get up to highway speed and have the trans NOT upshift when I let off the gas....they are a different animal indeed.

    Good luck.....use the warranty while u can

    Delayed shifting.....maybe its the drive by wire having an issue.

    I noticed (before) that while at highway speed, if I stomp the gas in order to pass or get out of a dangerous situation (drunk/swerving in front of me), the truck used to stay in 5th and bog itself down.

    Since I have had the urd maf calibrator installed, I can say I haven't noticed this problem....the truck kicks down sooner and moves....the maf calibrator leans the fuel some, and I wonder if it truly is helping or if its placebo.......either way its been on for 2yrs and I have no trans issues that I mentioned above.

    By piggy backing I mean the second I release the pedal its like I left the E brake on and I'm slowing down.if I'm accelerating and turning I can definitely feel how heavy the truck is... But I almost feel like its a dragging.

    At what RPM do your trucks shift at? I noticed my truck shifts at about 1900 RPM.

    Letting of the gas and feeling the truck slow is the way our trucks were designed.

    If you baby the truck a 1900rpm shift is correct. It is a V6 with decent gearing which is also another reason the truck slows when off the gas. Alot of VW vehicles are the same way.

    As stated disconnect the battery and it will learn the truck to you but it will not be changing much since what you are complaining about is common traits of our model truck.

    What were you driving before??

    none yet

    Same here! Maybe it is the symptoms of the taco and nothing mechanically wrong? When I accelerate hard, I hear more engine noise than I care to hear and the TACO would still be "dragging" or being sluggish. I do a lot of self-talks when I want the TACO to be more responsive and go faster such as "what do I expect from a pickup truck like this taco? It's not a sports car." I lowered my expectation and just keep on crawling forward :) :) :).

    I was driving a clk 320. I'm going to reset the computer hopefully im making something out of nothing. I drove a 2011 around and didn't feel that it any of the similar issues I reported in the OP that's also contributed to why I felt there was an issue
