Late (93) MTX trans Nashville

[zak]

92 saw the revision of both case halves and many of the gears, in 93 I think 3rd gear was revised, here is an example though a little dirty:

I don't believe that there were any changes to the MTX from 89-95.

No, Mark Nunnally spells it differently.

Any left over Nunnally MTXs would be pieces!

Ron, the part numbers for the cases and most of the gears changed in 1992, right around when they also redesigned a second MTX-IV for the Tempo V6. And third gear (the one that many have shelled over the years) has a 1993 part number. Gear ratios remained the same.
The box saw other revisions in its history including moving to the carbon paper lined blocking rings (around about 1990 if memory serves)

Post title says '93, but when you look at the pictures the paper tags say 91. So believe the CL poster, or the junkyard parts guy?

I don't think you can get the metal blocking rings any more in any case.

Tag on the case indicates F3DR or a 1993 or newer MTX (all three 1995 MTXs I have or had had this number on them)

Other than the change from the "brass" to the "paper" synchros, I don't believe anything else changed. Part numbers may have changed, which make it possible to sorta date a tranny (if anyone cares), but Ford wasn't about to spend another penny on that box. If the ATX would have come out in 90 like they hoped, the MTX could have disappeared before 95.

Yeah, the tag in those pics definitely shows 91. Doesn't matter, except as a bargaining point for a potential buyer.

With Ford, part numbers can change with no change in the part. Example, a 93 AC compressor has a different part number than a 94 AC compressor. The reason being, the switch from R12 to R134. It requires different manifold o-rings. Nothing actually changed with the compressor. Verified to be exactly the same.
