I have been looking through all the Transmission identification postings to try and identify the Ford-O-Matic transmissions I have, but have failed to find the exact ones I have. Can anyone tell me what I have for the following case stamps:

PAK-7006-C

PMB-7006-D

Also, what stamp code would indicate a transmission from a super-charged Ford?
 
Yes, I saw that information in an earlier post. Does that mean my PMB-7006-D is also from a T-bird?

Any idea what the PAK-7006-C was from?

The numbers above are CASTING ID NOS for the main case (7006) of the trans assy. PN PREFIX PMB would indicate MERC-O-MATIC (MED CASE).
 
I've never made much sense out of the Borg Warner/FOM numbering system. The first number, PAK-7006-C, was used in the 1955 Ford 272 with 2V applications and it's a small case transmission.

The second number, PMB-7006-D, I could not identify for certain since it wasn't listed in this listing. https://www.charlietranny.com/FordomaticID.htm

The PMB prefixes that were listed were as follows. The PMB-7006-A was used in 1955 Mercury applications with 292 and 4V carb. The PMB-7006-B was used in 1955 Ford 292 with 4V carb applications. The PMB-7006-C was used in 1955 T-bird with 292 and 4V carb applications. All of these are medium case transmissions.

It could have been a T-bird application that was short lived in that time frame. Maybe late in the model year but this is all just speculation.

The TRANS ID will have BASIC PN 7003 (7003 being an assembly).

A main case will have a CASTING ID BASIC ENGINEERING PN 7006.
