if your going to street drive it a lot, your going to want an aod or 4r70w so you have od. if your not going to run on the street often then c4. stay away from the c6, its very heavy, robs ton of power from the motor and is anything but bullet proof in stock form or even built up.

I have to disagree with you on the C6 while it is heavy and does rob power from the motor I have never had any problems with the C6 I have had about 4-5 different trucks with them all having well over 400 horsepower and constantly abused in the form of offroad, pulling, some racing, and never ever had one even hesitate on me. I love the C6 except for the lack of overdrive. I never had to get rid of one of them because of trans issues.

It may hold up to a 400-500 hp truck no matter what the type of driving is but they are not a great trans when the powers up in the 800 plus range, hell a c4 like my mightymite isn't that great in that range, if your going to get big power go with a turbo 400 or a 4l60e the gm trannys are just so much bigger and they hold more and thicker internals

Unless your making sick hp there is no reason for a c6. If your driving the car on the street alot 410s and a c4 is not going to like anything over 50-60 with out heating up the trans.
Aod's are good you can run the car on the street and still run on the hywy at 70. In either case and over sized trans cooler should keep things under wraps, make sure you invest in a trans temp gauge. Its cheap insurance for maintaining good trans temps also adding a fan on the tc can also help keeping the trans cool on the hot days or stuck in traffic....

Basically your main 3 choices are a c4, AOD, or 4R70W. That really depends on how much you want to spend on the trans. You can get a race ready c4 for under $1400 but an AOD will cost you upwards to $2000 easily. I loved my c4 but if I had the money I would definitely run a AOD that was built. If you want some good tech advice on them talk to silver fox over at www.clickclickracing.com. They also have some great tech articles on building a trans yourself.
