4.XX gears...will they fit?

Andy Smith · Aug 16, 2003

Will the gears from the old foci tranny fit the one on the PZEV? Maybe I should shoot FC an email regarding this since they are all over those gearing changes.

StickShifter · Aug 16, 2003

Depends on what year tranny they are for...Ford changed the MTX-75 somewhere down the line, and the gears available for the old ones dont fit the newer ones...I am not sure if the internal changes coincide with the 02.5 shifter change, or if it was separate...

The MTX-75 manual transaxle is a 2-shaft transaxle.

MTX-75 means:

M: Manual
T: Transmission
X: Transaxle (front wheel drive)
75: Distance between input and output shaft in mm.
The aluminum transaxle housing comprises two closed sections. Additional reinforcement ribbing has been added to the transaxle housing to reduce noise and vibrations.

All the gear wheels in the 2-shaft transaxle are in constant mesh. In each gear the required transaxle ratio is achieved by means of a pair of gear wheels.

When reverse gear is selected, an idler gear changes the direction of rotation of the output shaft.

The input and output shafts run in roller bearings.

To further improve stability and gear shifting, the selector mechanism has been revised to incorporate a maintenance-free cable operating mechanism.

All the gear wheels, including reverse gear, are bevel-cut, synchronized and run on needle roller bearings.

The first and second gears are dual-synchronized.

Ok...So Ford changed it more than once...

Peloton25 · Aug 17, 2003

So what's the verdict? Would a PZEV require an entire transmission swap to get better gearing? Or is the PZEVs tranny a workable starting point?

check out the zetec tuning forum. the gears can be made to fit with a little work, too lazy to find the thread, but ti's fairly recent.

I'm jsut bitter cuz i have an ATX

Peloton25 · Aug 17, 2003

I believe this is the thread you are referring to:

4.06 Final Drive Install Problems

Thanks for pointing me in that direction. It seems like there's more info to be gathered though.

Andy Smith · Aug 17, 2003

Certainly does seem like there's more. I'd assume our cars are like the 2001's and later, as far as having the 1 peice shaft, rather than the 2 piece. Hmmmmm

OmniFocus · Aug 17, 2003

I hate to say it, but I think it'll take a brave soul to yank the transaxle from his PZEV and tear it apart to find out EXACTLY what we need to know.

This issue is near and dear to me, because I want a PZEV, but ONLY with a quaife and 4.08 gears.

But wouldn't 4.08 gears zip by real quick in an autocross? I would see a lot of 2-3-2-3 shifts. With the 3.82 in the Zetec, I would almost top out 2nd on most courses. Granted, these would really give the car some zip. Plus, I think that would bump you to Prepared or Modified.

In short, I would love to have something higher that 3.55s, but I'm worried about how it would affect autocrossing.

Peloton25 · Aug 17, 2003

So what about just fitting the 3.82 from a Zetec - wouldn't that give you the best of both worlds so to speak? I realize the car would be quicker with the 4.06, but something is better than nothing right?

Absolutely... It is a big step in the right direction, and MAY be an easier swap.

Egz... I'm thinking of buying the PZEV for pure fun... We already have another silver zero-option PZEV in line for HS action next year.

Re: PZEV / MTX-75 Info

Greetings,

I would like to share some important information with you. I have just completed a 4.06 conversion in a PZEV Focus. The PZEV cars use a tall final drive ratio, but all other ratios are the same as ZETEC cars. A 3.82 swap is an easy "drop-in" swap. The 4.06 Swap is a bit more complicated. In either case I don't recomend it as a do-it-yourself modification.

For more information, I can be contacted here or through my website.

Great to hear man! While you're in there you might as well just go for the 4.06's I think

Nice site it has the be one of the best places to learn about the MTX75.

I have soo many questions,,

what is needed to convert a ZETEC MTX to a PZEV MTX? Is it posible to convert the 2000-2001 shifter to the 2003 shifter?

You guy should become a Focaljet sponser.

The tranny from you guys and the engine from Gerry, and we have a swapablw Duratec drivetrain.

Hey do you have a picture of that intake and header for the PZEV? I'd like to what you guys have to offer for me right off the bat! You're the first to the market with this stuff

Re: PZEV / MTX-75 Info

Rep yourself like crazy. THere's a lto of buzz about the PZEV on here right now and many of us are counting our pennies in anticipation of making the switch to the duratec lump. Especially since it seems liek your crap ISN'T vaporware.

Post Dynos and they will come
