Identify an automatic trans out of a 70 f100

[wobblefoot]

I went to the pick and pull yard yesterday,and found this automatic trans in a 70 ford f100 with a 302.
The only number I could find on it is C97P-7006A.
I know the C stands for 70 something but any other way I dont know how.
Anybodys help would be great.

I made a mistake the number is C9ZP-7006A.
After more looking Ive found C9=1969,Z=mustang,P=automatic.I cant find what the 7006A stands for.
thanks.

I power washed the trans today found a tag on the other side of the casing that looks like its screwed in with screws that says 9 C4,so Im guessing its a c4.

The number you found is called an engineering number. That does give you a specific application for a part but does tell you what it was originally designed for. Ford only changes the number when the part is redesigned so in theory you could easily have that C9ZP number on a 79 Ford truck. C9ZP-7006-A is the engineering number for an FMX main case. This means the case of the transmission was originally designed for a 69 Mustang but they were used on almost any car that had an FMX in the 70's until a design change took place. C means 60's, 9 is the year, Z is Mustang, P is transmission and driveline, 7006 is a main case, and A is the version. That number really does not tell you anything unless you happen to recognize it as you can't actually look it up in a regular book and cross reference it. Hawkrod
