Auto trans performance / Nismo, does it learn how you drive?

By cold, I meant the transmission not being up to temp. My bad. When it's actually cold (below 50F), the lurching and sluggishness gets noticeably worse. When it's above that temp and I'm cold starting the car, the transmission is slow but not overtly sluggish.

Good high-quality full synthetic ATFs will solve that. Redline is my brand of choice, but there are plenty of others that will exceed the performance of OEMs. Amsoil, BG, Valvoline...to name a few.

For example, in our Jeeps when we lived in South Dakota, the OEM Mopar 8/9 ATF and ATF+4 just didn't cut it in those brutal winter temps... Insert Redline D6 ATF and C+ATF and it's a whole new ballgame. Again, just as an example, everyone will have their brand of choice so work with the local specialty and/or performance shop you're comfortable with.

I'm still using the factory ATF. Afaik, there is no aftermarket ATF that is safe to use for the 9AT.

Is there anything that meets Mercedes" spec? I haven't dug into it yet, but I believe I've seen the truck guys using Motul.

First gear is only useful when coming to a stop or doing launches. Most driving will be in 2-9. On track, I find myself staying between 3 and 5.

True. Staying in 2nd is the part I hate the most of this transmission.

I test drove a Nismo z 2 months ago, enjoyed it
Tested another one yesterday before going to pull the trigger and.... Almost hated it?
There was a sensor error which they said is just a software update part and needs nothing on screen during drive

Regardless, primarily in sport but also standard iirc it would skip shifts. So like hold onto 2ns gear then finally realize I'm not tramping it and went to 4th, or it would like do ultra fast mini shifts but you'd feel everyy one of them almost jerky like? Like from 7th to 2nd or something


Is it because their dealer principle who has been driving it has been thrashing or driving funnily hence the trans is behaving funny, or have I just been misled by my first test drive compared to 2nd?!

Is this the same 9 spd in the Merc glc which is considered meh? I'll deal with a manual on daily if it's this bad and jumpy normally...

I have a 24 Nismo and don't know what you are talking about
But you need to warm it to operating temperature before standing on it.
