I have revised this thread to include both manual AND automatic transmission information.

I'll have to start out by apologizing to you Ford, Mopar, and everything else guys. I have a strong GM background, and the rest isn't really greatly covered on the internet.
If you know of something that should be here shared for everyone, let me know and I will try to put it in here with credit going to you for sharing it.

I put this up as an identification thread to help us all out.

I will try my best to describe the link contents for ease of finding the information you may need.

Doesn't this little dude look like he's smashing a bellhousing?

AUTOMATIC TRANSMISSION PAN IDENTIFICATION BY SHAPE & BOLT HOLE COUNT.

I unstuck my "The Chevy TH-700R4 Transmission." as it was added to the ranks of the Knowledge Base with it's own page.
The sticky thread I had on here is located at the following link.
http://hotrodders.com/showthread.ph...0R4+Information

The TH-700R4 Knowledge Base cluster is here:
http://hotrodders.com/kb/transmissi...s/TH-700R4.html

This TH-700R4 information has been around for as long as I can remember but I can't think of why I did not post the link in here before now.
Thanks to *Frisco* for the reminder.

The TH200-4R is identified by 10 bolt holes and 2 dowel-pin locator holes on the universal bellhousing. It has a dual "universal" bolt pattern for both Chevrolet L-6, 90º V-6, and all V-8, and BOPC (Buick, Olds, Pontiac, Cadillac) applications. The TH200 has only six bolt holes and 2 dowel-pin holes.
There are rumors/myths/urban legends of a TH-350 with the "universal" bolt pattern, but many hours of searching on the internet and asking other members here on Hotrodders.com have resulted in nothing conclusive. Yet!

Sometime in the future I will have enough information to deem a second page necessary, I will most likely seperate the automatic transmissions from the manual transmissions.

So I decided to give my Transmission Information sticky post a "page 2".
