This weekend I finally changed out the transaxle on my Focus. ETCG on youtube has a great video you can reference on how to do this. His video is a clutch change on a 2002 Ford focus. You have to remove the tranny to do the clutch. I wanted to share some learnings with others that might need to do this.
1. First check the transmission number in your car carefully. (I relied on the dealer; unforturnately one dealer told me my car had XS4Z-7002-DE; When I pulled it out I noticed my car had XS4Z-7002-DD). Which sucked because I had already ordered the DE one from Canada and it had been delivered to me already. The transmission part number is marked on the top of the transmission on a white label with barcode. It is under the air intake and battery area on the tranny.
2. The second point. XS4Z-7002-DE fit into my car and worked properly. From what I noticed visually; the housing (black cover area) is different. I'm not sure if they are different internally or not. Another note is that one of the dealers told me that after the DD trans had gone obsolete Ford referred customers to buy the DE tranny. This is what gave me confidence that they were interchangeable. In my case, the DE did work in place of the DD.
3. Also, its a good idea to change the input shaft seal and axle seals to avoid losing manual transmission fluid. This is what I changed. Do it right and do it once.
4. Ford sells some manual transmission fluid.That is what I used. XT-M5-QS
I hope this helps someone out. Good luck.
