    I think I heard somewhere that the 200r4 trans is the same length as the turbo 350 and that you can use your stock drive shaft. Is this true and what should be done to beef it up to handle 400 hp and tourque? Thanks CC

    Got my 2004R from Chris at CK performance and loved the upgrade.

    I did this swap a few weeks ago. It was easy, just had to do a little modification on the cross member. I put it in for power tour, made the tour and blew the front pump on my way home. I had all the upgrade parts but not the time to install them. I am only running 350-375 hp and puked a freshly rebuilt stock one. I was trying to save money and swore I would take it easy on it for the tour, couldn't help playing a bit on the gm proving grounds though. Cost me an extra 1000 miles of driving to go home and get my truck and go back and get it. Lesson learned. Make sure you get the upgrades. Oh, I did get around 20 mpg with a 3.73 rear doing 75-80 on the interstate :)

    I have a 200-4R trans in my Buick GS. From the Buick board, and these transmissions came in all the Grand Nationals, there are only three names that come up as being the best at building one to take abuse.

    CK Performance http://www.ckperformance.com/resources/GM2004RCATALOG.html

    Janis Transmissions in Akron, OH http://local.yahoo.com/info-15649588-janis-automotive-transmissions-akron

    CPT Transmissions in California (Art Carr) http://cpttransmission.com/

    I got my parts from CK, and Vince Janis built it for me. His shop is only 25 minutes from my house, so it was a no-brainer for me. Four years in my car behind my 462 cid Buick engine pushing 500 hp and no complaints.

    There are several other good 200-4R builders. Lonnie@ Extreme Automatics is one, Mike Kurtz in Tx, and a handful of others that can make them live.

    I've asked this question before, and what I got was "do you really want to use your stock driveshaft b ehind a 400 hp motor?". Driveshafts and U joints are usually one of the first driveline upgrades I guess.

    I'm sure there are other reputable shops that can build them. These are the three that the Buick community always mention when someone wants a good transmission.

    In the Turbobuick community,
    I've never seen CPT recommended.

    CKPerformance, Extreme Automatics, Vince Janis, Bruce Toelle, David Husek, Jason White, Otto's, and myself were most of the heavy hitters in that market. I quit dealing with them due to demand for my 4L80Es and some issues with the aftermarket parts quality, I believe some of the others have quit or slowed down.
