Thanks! That's what I'm worried about ... Re-build. My plan is to replace the 225 with a 318. I HAVE the 318 AND a 727 transmission BUT I'm not ready to do the swap yet. So rebuilding the 903 trans to keep me until I can do the swap, throws a total wrench in my budget!!!
My husband questioned whether it is a 903 or 904 or 902 trans BUT the '66 service states that the /6 had a A-903 trans. How do I KNOW what kind of transmission it is?!?!?
Have a great day!!
