is 7AT changeable?

docaam · 11-08-2010, 01:46 AM

As some of you might know I have 7AT Z along with DD 5AT 07G sedan, and am all set to pull the trigger for GTM SC.

As there is a valve body upgrade available for the 5AT, so I was thinking if swapping the gearbox between these two cars is possible or not? The only reason here is I can the 5AT with the upgrade till something comes up for the 7AT, even 5 gears would be enough for me in the Z. Just not looking for too many alteration if its a bolt on thing would be nice.

Any comments are appreciated

Give the guys at Level 10 a call. I am sure if you send in your 7AT valve body and torque converter, they could work on them.

WHy not just try out the 7sp until it goes then look at that option.

I have 5AT in my G, which if the alteration is not a big issue then I can swap the 7at in G and 5AT in Z along with valvebody upgrade? but need to know if possible or not

I don't think it's doable, really... the ECU will be looking for a 7AT, not a 5AT... lol

you might need to do some ECU tuning to get it to work or at worse case modify the ECU to adapt the 5spd trans. Man seriously just SC the G. The HR engines does better than the VHR with SC's thanks to the fact that it has no VVEL sci-fi technology

The thing is I might be getting rid of G in the near future just the plans as very difficult to mod two cars and G is more of a daiily for me 250miles per day trip

But as of last night FI plans are cancelled for sure, but I will be going for NA built with some goodies and a tune, meanwhile starting another project

My installer told me gearbox is not n issue easily doable but anyways it was only for SC

This swap won't work. It would be a massive wiring job and I don't think anybody would want to take that on. You're going to be stuck with the factory trannys in both of these cars.
