I don't recall building any TH375s, or seeing them mixed in with the stock on the floor.
In this context I believe the MX1 refers to the TH400 (merchandised RPO for a non-overdrive automatic; MX0 being an overdrive automatic). MM3 and MM4 are Saginaw three and four speeds, respectively, and MM7 is the New Process overdrive manual MY6.
The Saginaw 3 speed was offered with two first gear ratios, depending on the application (M62 and/or M64), column shifted.
