Jim: The 200-4R transmission isn't the same one as the crappy ole TH-200 used in the GM A/G bodies of the late 70s/early 80s. It does share the unfortunate "200" name, but it's only that in name. The 200-4R is actually a pretty durable little tranny. The Buick Grand Nationals and GNXs used a slightly beefed up version of this unit, and they're known to tolerate a reasonable amount of abuse. This trans was also used up through about 1990 in a lot of the large GM B-bodies, i.e. Buick Estate Wagons and Olds Custom Cruisers and Cadillac Fleetwood Brougham--essentially any of the RWD cars that DIDN'T have a Chevy engine. Now, those "Metric" TH-200s used in the late 70s WERE a buncha junk, but that's another whole topic. AMC content--I'm still leaning toward a 2WD AW4 for my Spirit 4.0 project.

Have you considered the 200R instead? I have never run one of those trannies but folowing the GM guys chatter they like the 200 over the 700 the same way as we like the 904 over the 727, less rotating weight and a good performer with the proper precautions. Cheaper too.
