Another platform to use our AX4N?

[1995mtxsho]

Are there any other cars that use the same spec AX4N as the SHO?
the 4.6 conti looks identical but is the bellhousing the same??

In a word, no.

The AX4N in the V8 SHO is unique to the car, and while another AX4N could be made to work, it isn't worth the extra effort.

 

[1995mtxsho]

I was looking more for why it isn't the same rather than just "a word". This is the discussion section after all.

I know it uses the same range switch, the same vane speed sensor, the same plug for the internal solenoids etc., but things like the bellhousing and input splines, etc are unknown to me.

There are no other cars that have the same 'spec' AX4N as the V8 SHO.

The bellhousings are the same on almost all AX4N's.

So an AX4N that bolts up and is rated to handle significantly more HP and Torque, wouldn't work as a viable replacement?

 

[St Louis SHO]

It's still going to break.

Which AX4N is that?

All HD or "performance" rebuilds of AX4N/4F50N trannys are done using V8 SHO specs, with some additional changes added in. The Conti AX4N is the same as a Vulcan or Duratec AX4N except it gets a different converter.

Umm the 4.6 liter Lincoln continental AX4N.
It's certainly a more powerful engine, therefor should be just as stout as the SHO's.

Hence the original question of the bellhousing, and then the comment about the input shaft splines.

I do, however, believe there has to be a difference between the regular 2.5/3.0 AX4N and the one in the 4.6 continental to make it hold up to the increase in power like the SHO.

 

[38SHO]

the input shaft splines are more going to be related to the torque converter then the engine... if there are any differences at all.......

and i think the outputs for the CV axles splines are the same for all taurii

I thought the 90s windstars had the AX4N trans in em?

the later 90s and early 2000's i believe.

The premise of your question is flawed. Just because the Conti AX4N was bolted to a 4.6 doesn't mean it was "upgraded" in any way. You're making an assumption that unfortunately doesn't hold any validity.

What you think and what is reality are two completely different things. Logic has little to do with Ford FWD transmissions. Again, the AX4N in the Conti is the exact same as the AX4N/4F50N on any non-SHO Taurus/Sable/Windstar/Freestar/etc. The only difference is the converter and the VSS placement depending on year.

You have to remember that the computer calibration for the Conti was configured for Lincolnesque driveability, not mad powah. The power and torque curves and how they were ramped in the calibration in the Conti were considerably different from the SHO.

Ok, point taken.
The next logical question would be; what is different in the SHO transmission that sets it apart? Aside from the obvious torque converter and vss placement.

Again this is just intended as a discussion for finding facts, as it is difficult to find solid information about differences and specs.

The SHO AX4N doesn't have a VSS and can't use one. A snout-mouted VSS will hit the rack, and a barrel-mounted VSS will hit the exhaust manifold. That's why the SHO gets its speed data from the ABS system.

Depending on the year of the tranny, there are additional frictions and steels and unique bonded separator plates in the valve body for additional **** and pressure.
