Transgo Shift Kit
The clunking sound is when you downshift in MM from 3-2 or 2-1. The 03 and 04's do this without the VB upgrade.
I don't know about the 05s which have rev matching.
Normal driving you can't tell it's there unless you are looking for it. Basically the shifting is a little firmer normal driving, but not enough to spill your coffee or your passenger asking what's wrong with your car.
I let my father drive my car he couldn't tell until he floored it to pass someone on the hwy. Now he wants a VB upgrade for his HD F-150.
If the weather was better I could make a vid, but we just got 50+in of snow in the last week.
Thanks for the comment on youtube I used to be boosted, but with the stillen VB I bounced off the rev limiter constantly. Check out my other vids denchan36 on youtube. Those were with the stillen.
I plan on boost or nitrous in the near future.
I would do the upgrade whether FI or not.
are you still on the fence about getting the VB upgrade?

I used to do that alot when I first got the car because I didn't understand how to shift properly.
Now I never get clunks whether I upshift or downshift.
In fact, when driving, I tend to shift down to 3 (if I'm in higher gears) and let the car shift back to 1 on its own. It usually skips gear two all together and smoothly shifts back to 1 automatically.
If this is what rev matching is all about, then I think its safe to say that the rev matching feature in the 05+ G should help smoothen out the shift a little bit more than the early model year Gs .
This is vital information because not too much info is posted if any at all between the effects of any shift kits on each G coupe/Z model year from 03-07+
And no one's compiled a thread yet reporting how their Transgo kit or any other shift reprogramming kit works/shifts in comparison to the different model year G/Zs.
I'm willing to try this out on my G and will order one in the next two weeks. I'd like to either install it myself (doesn't look too hard) or worst case find someone local to do it since I don't want to be w/o access to my car for a week or more.
Thanks for your help
Mike, if you get this kit before I do and need help, let me know and I'll gladly swing by sometime and help you do it. since you know both you and I are looking to get this done. 
I'm actually glad you talked about this. In my 05, it doesn't clunk unless i'm upshifting from 2 and then 3 if I try to shift too quickly at the wrong point.

I don't think it will be too hard especially taking time, keeping everything clean and going slooooowwww. I think it'll be worth the experience to install it ourselves
Jeff, I'll keep u posted for sure! I can't wait. I actually was out driving tonight visualizing how much quicker the shifts will be.

Mike just keep me posted, since this is definitely the next mod I want to do.
If you want it done for you, you can send GTM your valvebody and they'll install and improve on it

+1 for summit. I got mine from them too- took about a week to get up here. Price was reasonable. Had it in for about 6 months and love it. Im getting my trans built by IPT so it might be further modified or they'll leave it in. Not exactly clear on it yet.
I know the shop that did my transgo also recommended a tranny fluid cooler. They stated that the stock design is very inefficient. It didn't cost much to add in at that point- I think all in was a couple hundred extra dollars. Took the guys most of the day to do the full install. Thinking back knowing I had no worries about the tranny overheating was more than worth the additional cost. I didnt track the car throughout that time but still well worth it for the hot days and those pesky mini vans with soccer moms who want to race (or get away from you- whichever.)
The prices I was seeing earlier in the thread are accurate. I was 250 to buy, about 700 for the install of everything and the 100 bucks or so for the cooler.

+1 on a larger, aftermarket ATF cooler. Its a good idea to keep the stock cooler integrated into the system, however, particularly if you are in a cold climate (heat up AT fluid quicker) or get stuck in traffic a lot (cooling benefits when there is little flow to the aftermarket cooler).
