Different than the VIN I'm thinking... Where is the date-plate located? Is it a code? Or printed as you noted? Thanks!

I have an FMX transmission... Is this stock/factory to the 1971 Mach-1?
These were the auto trans offered in 71

U C-6 Automatic

W C-4 Automatic

X FMX Automatic

The data plate will show you what came with your car.

On the driver side door, for FMX the code would be X

This is what it looks like

I agree, absolutely correct info.

 
yup FMX came on the low end cars 351-2V being one... my 72 is originally a FMX, changed to a C6.

 
Thanks for the information... I'm in learning mode! What are the difference between the C4/FMX/C6?

 
Lots of things are different. Weight, gear ratios, strength, aftermarket support, etc. The FMX is not a bad transmission but there isn't a lot of aftermarket support for them. The C4 is the grandfather transmission to many of the Ford's transmissions that followed.
