Transmission feels like it's slipping

    Have a 2015 TRD 4X4 that, when turning to the left at a slow speed, the tranny feels like it's slipping for a few seconds. My 2002 Tacoma did the same thing. Anyone else feel this?

    Hmm, are you sure its not the wheel loosing traction or the Trailer Sway Control kicking in?
    Trailer Sway Control helps the driver to by selectively applying brake pressure for individual wheels and reducing engine torque when trailer sway is detected. Trailer doesnt' need to be attached, just a feature of the truck.

    It's funny you should say that about your tranny slipping. I have a 2015 dbl cab SR5. Only 1000 miles on it. N The other day when I made a turn, but was giving gas I felt that mine too was slipping. I thought it was just me, since I could not make it happen again

    I thought i felt this a few times since i got my truck as well (2012) ... only when turning. i think it has something to do with limited slip or other features.

    I would take it to the dealer and take them for a test drive to show them what you mean. If it is normal (caused by something else) then at least its documented you addressed it if something else comes up.

    I agree with Sean. On a new truck if you think something is acting up then take it in. If it was only once then you can probably afford to wait to see if it happens again, then take it in.

    I've been experiencing the same thing with my 2013 since day one. Every time I leave the stop sign at the end of my street, it feels like that if I give it too much gas. It threw me at first, but I don't believe it's actually slipping. I think it's just the throttle revving before the tranny has a chance to catch up. I haven't bothered to check, but I'm pretty sure our throttle is fly-by-wire rather than direct connection from the pedal.

    Fly by wire is correct

    I've always felt that it was the transmission had down shifted to a lower gear than I've been used to in other, lesser geared vehicles; allowing the engine to rev a bit more, then upshifting making it feel like it suddenly "catches".

    yep bank account is running low from it..
    Sounds like the transmission computer is trying to hunt on you. The computer cant see what your next move might be turning left or right. Unless the traction control is seeing something? Im going to assume no lights are on the dash indicating a problem.

    All that said like sean and csviper take it to the dealer see if the tech can reproduce the problem or the tech can check computer in the transmission like fuild temps and presssures to see if a problem is internal.

    Im going to sound retarded here but have you check for any leaks under the truck and wet? Reason I say we have one post of a looks to be a bad seal on there transmission of course Toyota is taken care of it.

    Like I mentioned, my truck does this; the 07 Sienna we just picked up does this; my work vehicle, a 2014 Blue Bird with an Allison transmission, does this. Is it possible that this is the software programming and that some of us simply aren't accustomed to slushboxes with more that 3 or 4 ratios?

    To a degree, it "feels" to me that the transmission's ECU base programming is downshifting in anticipation of a more aggressive throttle application after braking for the corner putting the engine at a little higher RPM (by maybe only a few hundred revs) so it pulls better, rather than lugging from closer to just above idle.

    ...of course, I could just be overthinking it. :)

    I left a stop sign today at lunch (turning left). It was a bigger intersection, with more driving straight before the turning left. I heard and felt my rear end/transmission banging. At first I thought it was my lunch box sliding against my tailgate. Then I realized my lunch box was in the back seat.

    I've noticed this same thing on my new Tundra. I've also felt it on several other new vehicles (different manuf). I think it exactly what Wynnded mentioned - it's the programming of new transmissions. I am only speculating, but I bet they are programmed with that delay in order to improve MPG - slower engagement, no mega launches from stop lights, etc.

    Honestly, it's quite annoying to me. Do any of the programmers/interceptors alter the shift points to improve this?
