For me Im working things out on both levels going for GTM SC kit and looking for any available valvebody and trq converter to be on the safe side, as getting a used tranny is not such a big issue but then getting that down to dubai is a big hassle.

lol Docaam, where you talking about me?

thats true guys, im the owner of that G, Its powerfull, it have more torque than the 5AT..shift faster, but it will not last long..

I got transmission replacement from dealer although i was not stock.

if you wanna FI your car with ur 7AT then i suggest you to wait for gtm to creat a valve body update, torque converter and etc etc etc.

I was also 4k into saving for a gtm stg 2 SC kit, but with the 7AT breaking from so little power (considering it was only 6psi) i just don't know. I'd upgrade the tranny aswell but i don't want too spend another 2k+++ just so i could drive it, i'm not looking for crazy power just what is offered with the kit.

Im out now too, dont want to pay for a new tranny so, I will be looking to get a 2011 vette around Aug/Sep 2011 when they are selling them cheap to get ready for the 2012s.

hehe. One auto tranny going out of how many F/I cars running and everyone bails. There are other people running auto trannies and there are no problems.

agreed many auto guys but i still have to hear from some 7AT guy then, as I said im still trying to convince myself

Im not sure how many will agree but FI for me is that I dont need that much power but I want that much power

It depends what failed and why.

For example, our auto trans is a bit different than traditonal slushboxes -- it has lock up in 2 -7th gear.

In regular auto mode, calculated load determines gear shifts; if the load tables get altered in the tune to account for the extra air mass from boost, this may mean a lot of weird gear hunting and increased wear and tear on hard parts (i.e., due to lock up rather than fluid coupling), which leads to failure, especially with the extra torque passing through the converter.

That's harder to correct, but might mean things have to be tuned differently.

Or it could be something simple like cooked AT fluid. It's non-serviceable, so difficult to inspect.

Would help to know more details about the problem...

ok pass dont trust any cheap parts

...whats next to offer?

puckshaw · 11-07-2010, 01:06 PM

Looks like I'll have enough saved up for FI in the next couple of months. Probably go with this kit once some more dynos are available. Really hoping to see some good numbers. The Stillen thread has been a huge disappointment. This kit seems promising.

shumby · 11-11-2010, 12:51 AM

ok guys FYI. Got a used tranny for 4000. I will be installing it in the car. My old tranny will be going to GTM. Sam will be loking at it to see wha\t failed and how. More to come but it will be weeks maybe months away as |I am in russia right now and getting this done while I am away. FYI as well i have heard of more then my 7AT failing.

Good luck Shumby. Sorry this happened.

Any updates on the fluttering issue?

Dixon, how is your build coming along?
