Transmission Build Code - First Gen TK5

[1qaz]

My apologies if this has been asked before...unable to find any references via search here or web search.

Is there a way to decipher the transmission build code on the side of a Toyo Kogyo 5-speed? Any way to match it up to a specific engine? Pic below...

It's out of my 1987 Ford Ranger XLT, 2.3L.

Thanks in advance for any help.

No, on the engine match up, TK-5 has detachable bell housing so that is not technically a part of the transmission

E7 = 1987, E8 would be 1988, F7 would be 1997
7A = Ranger

7003 = manual transmission, generic Ford number for any manual transmission

AKA is an internal parts reference, revision number

Look for a casting number on the bellhousing, you may be able to get engine match up from that.
2.8l, 2.9l both used same pattern
4cyl would be different

EDIT: you said it is out of 2.3l so bellhousing will only match Lima engines, 2.0l, 2.3l or 2.5l they had unique pattern that doesn't match any other engines
As far as I know the same TK-5 was used in both 4cyl and V6, no ratio changes

Thanks Ron! Any idea what the 003040 refers to?

Doesn't look like a date code, could be serial number, but don't know for sure

Does it say R&D Code?

It says "Build Code". Just don't know how to decipher it. Will send Ford Customer Service a note and see what they say.

Hi, can I use the same tk5 gearbox on 4d56 mitsu engine? The engine is 2.5L...
