That's nice. Everybody always jumps on the GM 700 bandwagon, but you just can't tell them anything. Those 200s are all about gear ratio. Look at the difference:
Transmission 1st Gear 2nd Gear 3rd Gear 4th Gear OD
Turbo 350 2.52 1.52 1 N/A
Turbo 400 2.48 1.48 1 N/A
2004R 2.74 1.57 1 0.67
700R4 /4L60 3.06 1.63 1 0.7
4L80E 2.48 1.48 1 0.75
As you can see, the 2004R has the closest gear ratio of any of them. People who use the 700 and think they have a better transmission are spoon fed wrong information. They always throw up the 3.06 first gear as being great, but that's what makes the 700 SUCK so bad. LOL The 2004R was built for acelleration. That's why they are such a good swap. But you can't tell some people anything.
