C4 Transmission Rebuild and Swap
While searching the local Seattle craigslist "Free" section, I came across an ad for a 1966 case fill C4 transmission from a Mustang. I had been wanting to replace my Ford-o-Matic so I figured this was the perfect opportunity. I picked it up on a rainy day and placed it in the garage to dry out. Nearly a year later and a 1,600 mile round trip to the FCA National Convention in the near future...I decided it was time to get it rebuilt and installed.
On a scale of 1 (easiest) to 10 (most difficult) I would say this project was a 6. If you're mechanically inclined, patient, and don't mind getting dirty, you can save yourself a good chunk of money by doing it yourself. I won't get into the specifics of most of the rebuild as there are other good sources available for that. I had help from a friend who had just recently rebuilt a later model C4 and he also loaned me the Haynes Techbook #10355 "Ford Automatic Transmission Overhaul" book and a video by the company Technical Video #1204 "Ford C-4." These were both excellent sources of information with easy to follow, step-by-step instructions.
I rebuilt the transmission over the course of a few weekends and decided to take a Friday and Monday off work to do the swap. My rebuild was strictly stock as that is more than sturdy enough to hold up behind my 200 i6. Although I still had a few details to work on, I got it done and was driving to work Tuesday morning. Below are some photos I took during the process along with comments and a few links I found helpful. Also, scroll down for a list of the expenses involved.
