ATX to MTX Swap Guide
 
Focus 5-Speed Swap


Introduction


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):


General

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)
5. Appropriate strength Jack stands (4 will do, but have 6 for safety)
6. Appropriate strength Jack
7. Mechanics Tool set
8. Clutch Alignment Tool
9. Pry Bars
10. Breaker Bar
11. Torque Wrench (good Quality)
12. Electrical Tools/Materials (Soldering Iron, Strippers ( ), Electrical Tape, etc.)
13. Work bench (or Work Table)
14. OptionalCreeper (save your back)

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.

Steps:

SAFETY FIRST! SAFETY FIRST! SAFETY FIRST! SAFETY FIRST! SAFETY FIRST!

Refer to the Haynes manual for steps requiring dismantling/installing). For example: Step 6. Remove the Center Console.

1. Get all the parts first!!!!
2. Clear Spot for the SWAP
3. Disconnect Battery and Remove (place on cardboard to prevent discharge)
4. Remove Transmission per the instruction in the Haynes Manual ( use Haynes Manual, it should have you remove the axles, starter, exhaust parts, etc.)
5. Remove the auto transmission cooler lines and cooler.
6. On the inside of the car remove the driver seat (makes things a lot easier)
7. Remove the Center Console.
8. Remove the blower box shield and the air directing box (below the stereo bezel, right above floor) (refer to image 5)
9. Remove shifter assembly
10. Under carpet where blower box was there is a two metal plates keeping the the lines from moving, remove this. Again, Refer to Haynes Manual.
11. From underneath the car remove the shifter cables, the grommet is under the heat shield which is above the flex pipe bend. 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.
12. Back inside the cabin, remove the Brake pedal assembly. You'll notice that Ford kindly left use a hole with a grommet that just so happens to be where the clutch pedal bolts up to.
13. Install the Manual Focus Brake/ Clutch Assembly. Remember to attach the brake connector.
14. Send the shifter cables through, this may be easier going from underneath the car. Tie up cables out of the way.
15. Install the shift tower and shifter (damn you should have bought a short shifter, doh)
16. In the engine bay, remove the automatic brake reservoir (Be careful! Brake fluid will leak out. Brake fluid is very bad for your health, paint, etc. have something to catch this and dispose of it properly) (Note: remember that you'll have to re-bleed you brakes, for safety)
17. Install the clutch/brake reservoir.
18. Remove the Axle mount (behind engine, below oil filter).
19. Install Manual Focus Axle mount.
20. Remove Torque Converter
21. Remove Auto Flex Plate (“an automatics flywheel”)
22. *!*!*!* FREAKING SO IMPORTANT, Forget this next 2 steps and you'll have a lot of headaches) *!*!*!*
23. On the engine, where the bell housing mounts, remove the Crank Position Sensor.
24. Install the Manual Focus Crank Position Sensor.
25. Install Fly Wheel
26. Install Clutch. (use the alignment tool!)
27. Install Slave Cylinder and Throwout Bearing on Manual transmission.
28. Install Manual Transmission. (use Haynes Manual, it should have you install the axles, starter, exhaust parts, etc.)
29. Make sure use the Manual Transmission Starter!!!
30. Also Make sure the tripod is installed.
31. Hookup Clutch Lines. Should be one from Res to Pedal, Pedal to Slave Cylinder, Res to Brakes
32. !VITAL! Install Clutch Line c-clips, otherwise your lines will blow out every time.
33. Fill Reservoir and Bleed, use the Haynes manual for proper filling and bleeding procedures.
34. Install Shift Cables to transmission.
35. Wire transmission harness using the guide in the Tools Section of this Guide.
36. Install re-wired harness.
37. Drain tranny of old Fluid.
38. Fill MTX with new Fluid (use GOOD fluid, I use Royal Purple) per the instructions in the Haynes Manual.
39. In the cabin row through the gears and adjust the cables on the transmission as nessesary. (Depress the clutch while doing this of course)
40. When satisfied, reinstall the center console, driver seat, and other ineterior pieces.
41. Button up the install check for loose connections and other misc items. Be Thorough!!!
42. Reinstall battery and crank it up. Make sure it is nuetral and foot on clutch. Before driving verify proper brake function and no leaks. You may also have to bleed the clutch a few more times.

Conclusion

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!

great write-up
hopefully I'll be doing a fully illustrated write-up on atx-getrag swap over the summa

boosted2nr 03-16-2008 03:25 PM

WOW. People have been asking for a long time for the details of this swap, but I get no love. :( No rep, no sticky .... that makes panda sad.

Hi, this is my first post. I joined just to say "thanks!" for the posting. This is something I plan to do eventually.

Two questions: How long did the swap take you, once you had all of the parts and tools assembled?

May I ask what the ball park price was for everything?

homegrown2nr 03-18-2008 09:15 PM

I went all out when I did mine, lightweight fly, torsen LSD, etc. So my build cost more than most will. I think I spent about 1600 on the swap, but using just stock parts, It could be done for about 5-600 (depending on the price of the tranny).

Everything on the inside of the car was was quick, about 2.3 hours for me. The wiring took about 1 hour. The biggest hurdle is removing the old tranny and components and installing the new. The amount of time to do this is variable, based on mechanical ability and availability of assistance.

boosted2nr 03-18-2008 09:17 PM

Keep posting, I love the input. I want this post to be as complete as possible.

xp0s3d 03-18-2008 09:18 PM

it's nice to have friends to slave the job on too hehe
