Could someone explain the “learning” a transmission does from how it is driven? I keep seeing references to how it adjusts based on your driving patterns but would like to know more. I am sure there is a great article on it on this site somewhere but being a newbie I can’t seem to find it. Thanks for any hints or links.

I admire your typing skills.

the "adaptation" is pretty frequent. if you want to drive hard all the time you need to drive hard all the time. if you spend like a trip babying it, it'll back off and be less aggressive

the only option is to leave it in DS and it defaults so some programmed "sporty" shift.

the IPL has a different program, tuned to be more aggressive.

 

Thanks... So it actually "learns" how you drive, and addapts to maximize performance? WOW!?! So my boring daily commute on surface streets should stay in "D", and then spend the weekend in "DS" (or manual) so I get the best of both worlds? It will be a better "boring" driver in "D" mode over time?

Thanks again for you response, I really have opened Pandora's Box, and am loving every second!

Apparently the TCM's programming actually has a shift aggressiveness table, with negative and positive values, and can be read/seen with the dealer computer and even altered. I think negative values = shift torque hardness, and positive values = softer shifts. I tried to get the tech to read my tables one day out of curiosity but he told me that if he read them, he had to reset them and charge me 90 bucks labor fee, so I declined.

There's another thread around here from like a year or more ago somewhere that discusses this in detail.

 

Thanks, I looked but guess I will have to look harder.

I have to add to this. So what I am understand is since I am purchasing a used car I can get it reset... Did I get this right?

 

Yes. Or you can reset it yourself

 

Doin it myself is a much better option. Is there a write up on it. I tried searching but didnt find anything

 

Disconnect the negative battery cable for about 30 minutes or so. This will allow all the cars capacitors to drain. It will reset.

 

haha easy enuf, thanks

 

 

well then... as HBSURFDAD would say
