Tune help AT transmission quirks? (Nismo or reg Z)

[HarryBo]

Wondering if tunes are helping to solve some of the AT transmission shifting concerns?

Looking at EcuTek for my "24 Nismo.

What problems are you having with the transmission? Had\have 2 auto Z's with no problems.

Still not tuning support for the transmission yet.

Tuners can miss around with the torque management which will affect the transmission shifting.

Ok. Thx. Darn.

The only thing I've noticed with the Nismo is that sometimes from a first gear launch 2nd gear doesn't hit or hook up as hard as rolling from 2nd. Any hit while rolling from 2nd on in sport + mode hits fast and hard, and is perfect.

Other than this, I have no issues with the transmission. I really don't pay it much attention when I'm driving around in normal standard mode.

Haven't launched yet as only 700 km on car. Good to know though. In regular driving so getting used to all three mode nuances, in both AT and M.

Hurry up and get that thing broken in! As soon as mine hit 1200 miles the first thing I did was test the launch control. You will love it! Be careful though, you don't want such a great car in a ditch. Leave the traction control on lol!

 

[HarryBo]

Haha! Good to know! Yes, can't wait to give the LC a go.

Either not shifting when paddle pulled, mostly 2nd to 3rd, or hanging on too long, or Jerky. Mostly counter intuitive. Does not happen often, just now and again. Noticeably, where my R35 GTR was wayyyy better, in normal driving.

Only shifting ’issue’ (if you can even call it that) is normal city driving not pushing it whatsoever, if I’m going slightly uphill, where it would normally shift around 1750-2000 it stays in 3rd sometimes to 3250-3500, then only stays in 4th for about 1 sec before shifting to 5th. Same in Standard, Sport and Sport+. I typically pull the paddle before it gets to 3k.
it’s never done that launching.

 

[HarryBo]

Sounds pretty minimal. Glad to hear.

I have an issue when running WOT using the paddles sometimes the up shift will not happen, especially 2nd to 3rd, it’s rare but does occur. Maybe I don’t pull it hard enough. So most of the time I just let the AT do the shifting and it’s never failed to please.

I did my first launch control at about 12 miles lol. Love that feature on this car. Agree TC “on” is a must!

My stock 24 Nismo had a 3-4 and 5-6 flare only when cold, manual or auto mode. I found that by driving in Sport mode it would eliminate the flare shifts completely.

Hhmm...I'll take note of that. Though I have found Sport mode less quirky as well in general.

Same situation with me. But sometimes the shifting takes a while. Some say it is because the tranny hasn't warmed up yet...
