I'm kind of bummed about the T56 hate 
Do T56s really suck that bad when you start making power? Even with a very good rebuild? I was always under the impression that T56s were stout transmissions.

Do not build a 4l60, they will brake even if its a "level 5" trans. One of our friends has already broke 3 built 4l60's.
Get a 4l80e , they are heavy duty and will hold all the power, they are A4 , so they are good for the street and highway. Its very easy to put it onto your car. As far as your PCM goes, you can use a your current pcm, and whoever is doing your tuning, tell them to do the 4l80e Transmission segment swap onto your tune and do a full flash back into it. If they have EFI Live then its very easy..
Then just get a Yoke, which is like 75 bucks locally. And a flex plate . Then just wire two wires onto the PCM, its easy, just search on the forums or on performancetrucks.net website.

I've been lurking the FI section for awhile now but I feel you. I just thought the weak link in the T56s were the hydraulics and/or not being able to keep clutches in the car. I didn't realize that even heavily built T56s were breaking all of the time.

personally, im not looking for a hp goal, im looking for solid 9's, based on where im at now it should be obtainable, but well see
getting it to hook can be interesting
that being said, i know my car would be slightly faster and more consistent with an auto than it is now, but the trans hasnt broken and i considered clutches wear items

I was a die hard M6 guy. Than i had to brake down and go auto for those that did not see the post here you go. going to a auto is by far the best thing for a turbo. the auto is way more fun to me than the M6 could ever be. 4L80 is KING

I guess it comes down to personal preference. Personally, I dont care if my car would lose 1.3 seconds in the 1/4 if I switched to auto, I LOVE to row my own gears. And I wont be trading it for auto anytime soon. My DD Z28 is auto, and granted its stock, but its is one of the most uneventful, boring cars I have ever driven in my life. lmao
