A: The 200R4 I had in my wagon was overdrive and not the 3 speed auto. I was 
very annoyed when it dumped on me during a trip to BC. I had to wait 3 hours 
for a tow truck and decided then and there to sell it for the first $100 I 
could get! (previous owner had it rebuilt and then replaced by Chev twice 
before giving up on it) It could be because it was only built to stand up to 
a 229 V6. The one in the '85 S10 with fuel injected 2.5L is suffering a 
similar fate, but seems to be holding in gear now that I added a can of STP 
oil treatment. (good enough for a town cruiser. Not mine!)
   As for an AW4 2WD, I posted on the Comanche list and may have a couple 
leads for you (they want to convert to 4x4 like I did and complain they 
can't find 4x4 trans for reasonable prices)

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.
