Transmission Slip

[donayre21]

I remember in my e46 BMW (2000) had a similar self learning transmission. We were able to do a reset on the learning when the shifts were becoming "lazy". When it reset, it felt more peppy and the shifts were "harder".

how do you reset the thing

for the e46 it was a combination of buttons/commands. It's been a while but im sure you can do a search.

Idk anything about the new 4R

Self learning transmission huh. Man that is some wild stuff.

This isn't anything new, transmissions have been doing this for some time now. They do this to match your driving style and make the shifting more comfortable for you. If you drive aggressively they learn to hold gears longer and down shift quicker. Drive more relaxed and they will upshift sooner and require more throttle for a down shift. However they do need time to adapt so withhold judgment about gear hunting or slow response until they have time to learn.

With that said, they should still shift smoothly and not slam into gears or slip, that's not adaptive learning. When I test drove one I did notice the 2-3 shift was very firm but I just assumed it was because it was cold and would smooth out when it warmed up.

If anything, it's telling how much of a dinosaur Toyota has been on the tranny front. Adaptive learning has been a staple ever since I drove 6R80 and 6L80 vehicles. It's just that it can only be as good as the transmission is good, cough cough incorrigible 10R80, and has a more visible impact in transmissions with more gears

I've driven another 250 miles and it hasn't slipped again. Really hoping it was just a fluke.
