7speed---6speed

I have an auto touring 2010. Due to the shift delay now I'm thinking about swap the transmission. The manual cost about $2000, does anyone have experience with this? Is it possible to swap it, and is there gonna be any side affects?

Sell your automatic and by a manual Z.

NYBladeZ · 12-01-2011, 12:42 AM

Way to labor intensive and risky. Sell and get a manual or live with your decision.

Nothing wrong with a 7AT

NYBladeZ · 12-01-2011, 02:16 AM

Except for lack of fun factor and limitations that require $$$$ upgrades when you want BIG power.

Beilieve it or not it may be illegal due to vin and smog laws. It is here in cali, witnessed a guy furious when he left dmv the other week...

If you're gonna switch, do this ^. There's a ton of little things different on the two, including the ECU, some wiring harnesses, the rear diff, etc.

But really, the shift delay thing isn't a big deal. I used to worry about it more before I had taken the car to the track because I'd sometimes see these big delays bopping around town, and it seemed kinda random. It's really not, it all has to do with how you're driving. The shifts are plenty fast at high RPM, in both directions.

you'll need the manual trans, manual car ECU, trans harness, and center console assembly, clutch pedal assembly and a few other lil things. not that labor intensive, we've done a couple on the older Z33 platform.

You will ruin resale value, though.

It seems to make more sense just to find a 6MT car close to your trade-in or private party value and just switch cars. You'll lose a bit but you will have a factory 6MT car and will be able to sell it easily if needed.

Blue370tt · 12-01-2011, 11:15 AM

OR.....You could just get the TRANNY tuned (not the ECU) with Osiris and increase line pressues and shift speeds. Thats what ALL the TT'd and SC'd 7AT people have done.

There are two separate components to the shift speed issues people bring up: control input lag and actual shift execution time. Control input lag is the one that's pretty constant, and annoying in low gears. You have to predictively click the button a bit ahead of time if the RPMs are rising very quickly in 1st or 2nd gear. In higher gears the RPMs are moving slowly enough that it's not a significant factor.

As far as actual shift execution time goes, the primary determinant is really engine RPM. The higher your RPMs are the more reliably quick the shift is. It's really a non-issue when driving the car hard, but it can feel a little slow down at pedestrian RPMs.

I've played with the UpRev 7AT torque-map (line pressure) stuff endlessly. If you set the values too high, the shifts get jerky (which isn't a good thing, it just upsets the car's balance and shocks the drivetrain). If you set them too low, the transmission doesn't achieve lockup (or doesn't achieve it as quickly), and you'll lose power and slowly lose your transmission to excess wear. The right value is determined by the power the engine is making. Setting it higher than necessary doesn't help it shift any faster.

raising the rpm you will find something differently
shifting fast more....since you are pedestrian driving do not care about
the slow lag shift speed....at the time you wanna get you blood boiling..
try the deep pedal ...auto z will not let you down..
