I totally missed the 2004r post! (sorry scott) I actually had my eye on one of those and that's why i bought the th400 crossmember originally. I have read alot about transmissions lately and it seems that the 2004r is not as capable of withstanding high horsepower or nitrous applications as the th400 is. I didn't know that the 2004r robs the least power (always a bonus). I plan to build an engine over the summer somewhere between 450-500 horsepower and might add nitrous (i don't drive it around town that much) I was too worried about blowing up a 2004r even though the overdrive would be very nice with my 3.90 gear set. Anyone have any experience with prices or work required for the 200 swap? I know it needs the 400 xmember, tv valve & lockup torque converter/wiring
