RPM or FLT Trans?
My car is actually at RPM as we speak getting their Level 7+ Treatment on the trans (A4). I'm actually local to FLT, but since I have been running a fully built RPM Differential with great success, I figure why go elswhere.
I had their level 6 previously, but wanted to step it up this year and not worry about the trans giving me problems. Lots of C5's over on CF running bottom 9's with RPM's Level 6 and at least one in the 8's with their level 7 A4. Jeremy has been great to deal with.
I've heard great things about FLT as well, but for me RPM is where it's at.

FLT level 6 here. Has never let me down and that's important when the car has to get you to work everyday. Chuck is great to deal with and I know that with him it's money well spent.
I have no experience with RPM, but from what I have seen, they build a quality unit.
As far as I'm concerned there are only 3 builders I would consider if one is going to use a 4l60e and FLT and RPM are 2 of them.

That's good info. How much power you putting through the Level 6 Sof?
Chuck recommended the Level 4 as it will hold heads/cam + nitrous pretty easily he said. RPM suggested I step up to the Level V if I want to run a bigger motor in the future.
I think they rate their HP/torque numbers a little differently with RPM being a bit more conservative.
The other thing I've seen is RPM has an upgrade path for their stages. If I buy a Level V for example, it's $xx to goto a Level VI and so forth. Waiting to hear back from Chuck after the Holiday weekend to see if they offer the same sort of path. I realize if there are problems in the tear down that cost could go up, but it's nice to know the minimum investment needed to step up in power.

RPM For sure.. I've dealt with Jeremy, TJ, Todd and Shane over there, every one of them will take the time to talk to you and explain things thoroughly.
I believe they build the best 4l60s around. Granted nothing is fool proof, bullet proof or unbreakable... Also **** does happen from time to time... But I have a lot of confidence in RPMs 4l60.
I haven't ran mine at the track yet with the 4l60, I'm waiting for good winter air, but I feel it will handle the low 9 sec runs I'm expecting.. Lots of C5 guys running mid 9s on them, a few running low 9s and even a couple in the 8s. Do they last forever? NO.. Do I expect to refreshen it after a couple seasons? Yes.. But considering its handling over double the HP the trans was ever intended for, its the price to pay.
My car was making 900rwhp with the stick, now the RPM 4l60e is in there handling the same power.. (Not sure what the rwhp is now tho...probably 800 or so).
The customer service alone from RPM makes it worth the purchase.

It was originally a level 5, I decided to go with a billet output shaft and a few other upgrades for my own personal reasons. Off the footbrake my car has gone 1.39 60ft, and considering the weight, and the fact that I have to rely on it for transportation not only to and from the track, but also to go back n forth to work I just decided to overbuild, not because it was absolutely necessary, but as a precaution. I built my car to reliable and to try and be fast, I'm confident the way it's built that I could load it up and drive it cross country and race if I wanted. It's already made multiple trips from Miami to Chicago. Could have I gotten away with less? Maybe - but I'm comfortable with the decision, and in the end the whole reason of having an overdrive trans is to drive the car, cause if I didn't I would have surely went with a 400 and saved a fortune

Can't say enough good things about RPM.
Great product, great service, talked me out of spending more $$$ with them than I needed to, etc.
Pretty much THE company of choice for big power 'Vette guys.

I'm thinking of going with a bit of overkill on this and going with the RPM Level VI Trans and the CircleD/Reactor Aluminum SFI flexplate. I'd be set as I go for more power down the road for a little more investment now.
