Can someone tell me what year and other information the numbers on my 904 tranny means?
Here are the numbers: PK4471534 9695 5953.
Thanks
Sean
 
PK = Plant, Kokomo, IN. 4471534 is the assembly number. I don't see that exact one in Paul Herd's new book on Torqueflites, but 4471535 is a 1988 999 lockup trans from a 318 with a 2.94 axle. 9695 is the date, based on the 10,000 day calendar, decodes to Feb. 12 1988. 5953rd transmission assembled that day.
