Hey, I was wondering if you could give me some info on this tranny I got for free. Under the FoMoCo lable it was stamped C20P-7006-D. I don't know anything about it and any info would be useful. Thanks

Ford sometimes used casting numbers which are difficult to figure out. The best bet may be to take it down to a tranny shop and have them look at it. Likely they'll know what it is that you have. Good luck.
