Focus 5-Speed Swap
The Zetec Focus uses the MTX-75 transaxle. The MTX75 is a great little transmission that was used on many different Ford models including the Contour. This is good news for us, because there are a lot of parts available through the Ford dealerships. In some cases, it is even possible to gather all the best parts from the various years of this transmission and built the ultimate MTX-75. Although, ONLY attempt this swap using MTX-75 from the Focus.
For those who inadvertently purchased the Focus with the crap Automatic (I was one of those people) there is a happy solution: the MTX swap. This guide is to help those who wish to dive into this endeavor. **However, there are a couple of points that must be laid out BEFORE you use this guide:
1. I DO NOT claim to be an expert of transmissions, nor am I an ASE certified technician.
2. I DO NOT assume ANY responsibility to those who use this guide. I am also NOT responsible for any damages/charges that may be caused by using this guide.
3. Double check any information given in this guide. Again, I am not responsible for typos.
4. This document, much like the Constitution, is a living document and as such, will be updated/revised periodically.
5. This document is not the end all-be-all authority on this swap, if I have forgotten or mistyped any information contained then PLEASE let me know!
6. This document is given as a GUIDE for this swap not a step by step SWAP. For instance, I will not explain how to remove the old transmission, etc.
7. I also recommend this swap be done by a professional shop.
8. Above all SAFETY FIRST!!!!!!!!!!!!!
When attempting this swap, you must be aware that this by no means “easy”. Depending on your mechanical ability, some may want to rely on a professional mechanics help. The swap also requires time, so think about this when before you put down your vital work transportation.
Ok, now that all the doom and gloom is done. This swap was a lot of fun for me to do and was also extremely educational. To me, the more work you do yourself the better you know your car and determine when things are going wrong and when things are going well. Also, Now is the perfect time to upgrade: Flywheel, Clutch, etc. Although, the stock stuff will work fine (in most applications).
Tools List (subject to updating/revision):
1. Haynes/Chilton manual or better.
2. SWAP Wiring Guide (pdf here
) All Credit to Gigaherz on FJ for this! Print it out.
3. Plenty of space
4. Money (sorry had to say this)

6. Appropriate strength Jack
7. Mechanics Tool set
8. Clutch Alignment Tool
9. Pry Bars

Parts List (subject to updating/revision):
*Important note: Make sure all the parts are for the correct year transmission. For example: If you buy a 2001 focus MTX-75, make sure the shift cables, shifter, etc. you get/buy are for the 2000-2002.5 focus. Another item to note is that some MTX-75's use mechanical speed sensors and some use magnetic. One more thing, I never installed the clutch safety switch (prevents car from being started in gear) so this guide will not go through that.

Pull the heat shield down a little to gain access (Careful !!! the shield is VERY sharp!). If it give you resistance check to make sure nothing else is holding the cables inside the car.

Hopefully everything worked out correctly and you offically have a Mnual Transmission Focus. Keep in mind that you will have the CEL and even the dreaded “!” on until you have a tune madeup to turn the automatic functions off. Enjoy.
Please let me know if there are any errors or additions that need to be made.
BIG THANKS!!! to Gigaherz on FJ for the wiring doc. All credit for that part is given to him. Without that this swap would be a lot harder!
