Do you still have the original 2004R? If yes, don't get rid of it. Get it rebuilt. That transmission is a special unit built for high power and is like having gold. It's the same Trans as in the Buick GN/ GNX. Only the GNs , the SS Montes and the H/O/ 442s had it. With a good stall converter it will be light years ahead of the TH350 trans and you got OD.

Also watch out who you give that trans to when getting it rebuilt. I have heard some shops will exchange it for the weaker trans thinking you won't know the difference. That transmission is very valuable.

It's not a shift kit. That is how the 442 trans actually shifts from the factory.

The 2004R has a 2.74 first gear and the Th 350 has a 2.52 first gear. The 2004R gives you a mechanically superior launch. Guys have spent thousands to equal the performance of that trans. Talk to GN owner,. they would never put a TH350 in their cars. Also the rear is special too. only the GN and the 442 have that 8.5 rear.

I see, Well the 3.73 will be a bit steep for highway travel, but if you want to do some stop light to stop light drags it will perform
well with proper hook up. And burnouts. Keep your camera handy for someone to take your picture. LOL

The 2004R trans are tougher to build right but 1000 rpm less on the highway is worth it. I chucked the TH250C and went back to the 2004R. I would buy a new double hump cross member, makes routing dual exhaust much easier, trust me.
