Why do people favor the longer geared mx6 tranny?

[bigtime]

Gro, I gotta question, did the 4.11 tranny feel like it lost anything from the 4.39 ?

like revved a little slower or had a bit less at lower rpm ?

I imagine it wouldn't really feel any different - just that you can rev a little "further" in each gear...

what you think Gro ?

I actaully posted a question about this ages ago but seeing there is a much more active tread here then I'll ask again. With the MX6 swap it's straight forward right? Just my clutch feels on the way out and when it goes I might be tempted to swap

You can follow most of the same info available for ZE's as far as the swap over goes to the MX6 DE engine. And since you're RHD you won't have the clearance issues that us NA MX'rs have with the brake MC. I'd use a combination of course of the various swap over "How to's" so that all of the gaps are cover wrt importing of coolant filler neck, disty, and ECU mods (if required when applicable to OBD II). The MX6 and 626 had the 4.11 gearing and the Probe and MX3 had the 4.39, I believe.

My reasoning is this:

The 4.39 gearing was designed with the K8-DE in mind. Since that engine lacks torque the gearing makes up for it by keeping it in higher rev's.

Thats quite possible, but the pgt also uses the same tranny. The klde has pretty much as much torque as the ze, so why do you figure the pgt didnt use the same tranny as the mx6?

I personally find the shorter gears more sporty and fun to drive.

I've been doing a little work will Ford on a project and an ex-coworkers cousin is a factory FWD driveline troubleshooter to the dealers. Made a couple calls and actually all the PGT did not have 4:11. when it was first released in '93 it came with a 4.38 and later depending on the wheel option they were used to compensate for the additional weight to keep the performace up to published spec. All the MX-6 and 626 had the 4.11 from start to finish of production. Since all 3 cars were build on the same assembly line just think of the logistical problems getting the right trans mission into the right car.

Makes perfect sense!! I've pm'd you regarding a related subject - thanks.

Thanks John - if this worked like ebay you'd be 'Great MX'er, superfast poster A+++++ '

Erm but i'm only talkin about the gearbox- all that about ECU and disty.. ? Oh and I don't even know what OBD II is..?

The "well what about the probe having the same gearing as the mx3" arguement is pointless.


you are overlooking a HUGE thing there. The probe has MUCH larger diameter wheels, thus their rev's are lower to begin with. Our car has tinydiameter wheels and with the short gearing it feels like driving an ITR.
