Need some tranny help-

[T Col]

Working on some other issues on my son's 79 F150 and was asked what PJA number my tranny was.

Can't find such a number, I do find "D50P-7006-AA" (that I have since learned how to decode without finding the answer to the question) and another (possibly correct, hard to read) "C6Z?-70027-A"

Anyone know what this PJA number may be and also, I thought I had figured this out to be a C4 tranny but that last number above kinda concerned me.

All support appreciated

That number is located on the tag that is attached by one of the bolts on the servo cover.

Yeah, I saw that tag on the diagram shared by Mil1ion but don't see it on the tranny

 

[DNFXDLI]

It could be missing, that is a very real possibility. The same things tends to happen to axle tags.

They installed C6 Trans on 351M/400/460 engines

Yes, Buck Tags are known to disappear but other than completely taking the trans apart to ID a part is the only Possible way to know what it is.

I really think it is a C4 based upon motor size and research

A C4 pan looks like a rectangle, with what I want to say, 14 pan bolts. A C6 pan looks more like a square with a notched cut away, with definitely 17 pan bolts.
