Totally disagree with the line of thinking (and PHR) on the comments that the 700 is stronger than the 200, that's just nonsense. You want a lesson on 200s & 700s, visit the turbo GN site(s) and do your homework. Another piece of advice that many have learned the hard way. Don't go to BTO for a 2004r. Neither a 700 or a 200 will live (for long) behind more than 600 ft lbs, and over 450 ft lbs the life is limited, especially with slicks.
If you're stuck on going 200 (or 700), than there's only 3 places to go for it:
CK Performance
PTS
Extreme Automatics
JakeShoe (Jakesperformance.com) is considered also one of the best, though not sure how many he does anymore, or what his backlog is.
I just went through this with a Pontiac, and am now in the middle of installing a 4L80e, since in my opinion (and anyone who knows and isn't going to lie to you) it's the ONLY option, especially in a higher torque & horsepower application. A built 4L80e will take 1200HP/ ft lbs all day long and not even break a sweat. The most anyone will ever say a 200/700 will take is 800, and that's the limited life thing again.
THE computer to get for the computer controller trans is the CompuShift unit. Once you install a computer controlled trans, and you've 'gotten by' with one of the other 'fixed' units, you WILL want to upgrade, so bite the bullet from the get go.
Cost for upgrading to an OD auto is about $4500, be it a 2004r or a 4L80e, the difference is very little. A well-built 2004r costs bucks because there's certain hard parts that are REQUIRED to make it live, and those parts just plain cost. Converters for a 2004r, again, one that works and lives, are between 700-1000 bucks. If you are changing from an auto to a manual, you will see that the cost will climb up close to that anyway, so again it's a wash. A Gear Vendors unit is $2500, a good built TH400 is $1000, and a good converter, like Continental, is another 800-1000. Again a wash.
My BTO level III is being rebuilt by BTO (warranty, 2nd time), replacing the converter, and I have the TV Made EZ kit with a Lokar. Once it gets back from BTO, I'll sell you the whole thing for $1500 obo plus shipping if you'd like.
