OK, I will have to contact the guy with that trans. But maybe you can
help me ID which one I have now. This is an 85 Custom Cruiser with
the 307 5.0L Olds engine. It has the 3speed W/ OD (or also seems to
be known as a 4speed). I have looked on the web for hours, and it
seems that the THM 200 & 2004R are my only options for a 1985 car.
It appears that they began using the 7004R in later models. How can I
know for sure what I have? Does the vehicle VIN number contain that
info, and if it does, how do I decode it? Otherwise, is there a
number somewhere on the transmission, and where?

At least if I know what I have, I can start to know what will replace
it. The guy at the local parts store thought I had that 700XXX model,
but I am not finding any of those 700xxx ones used in the 1985's.

I appreciate all help.

Look at the pan. If it's long and seems to be almost split into two
sections, it's a Thm200r4. If your sure it's a four speed, that's about all
it could be. The Thm7004r comes in Chevy only bolt pattern (the 200R4 comes
in a dual bolt pattern that will bolt to BOP and Chevy engines.) If the
Chevy trans your looking at has a vacuum modulator then it's a 3 speed.
(probably a thm350).

If it is an Overdrive transmission it is a TH200R4.

Olds-Biuck-Pontiac use the same bellhousing bolt patterns. Chevy uses
one of it's own. You should be able to get the correct transmission from a
salvage yard for $150 or less.
