Dumb ATX question

[JohnW63]

OK. the kit I got from Napa has the rubber gasket. I stated by finding the Felpro gasket number, then going to Napa online and finding THIER part number. When I went to my local store, he looked up the part, then I asked if they could get the filter. He typed way and said it was 12 bucks for both. They came in a single box.

I have a 97 and it says AX4S on the pan. What the ****, I wonder if the original owner of my car had the pan replaced at some point.

The AX4S has 17 bolt pan and the AX4N has a 19 bolt pan. If your pan says AX4S then that is what you gots.

Despite the overwhelming desire to do so, I'm going to resist the temptation to rename this thread "DUMB ATX ANSWERS". :shakehead

I meant to say synchronous. Somebody else said sequential and it messed my mind up. This does not require you to be a total ******** about it.

Synchronous transmissions require two seperate actions to accomplish a gear shift; 1st gear disengages, then 2nd gear engages. Hopefully this all happens at the same time; thus the 'synchronous' part. The mustang's C6 transmission had a **** of a time with 1-2 shifts messing up the tranny on hi-po stangs; all the torque was causing the shifts to be, well, not synchronous, and damage resulted. Lots of it.

Non-synchronous transmissions require only one action to perform a shift; much like a SEQUENTIAL manual transmission, only nonsynchronous (man, that word gets hard to type after a while) can skip gears. I remain firm on this point. Neither my 94ATX nor my 95ATX is capable of skipping gears; both will - very briefly - shift into 3rd before it slams into 2nd if I floor it going 60. More than one gen3 SHO that I've ridden in has skipped 3rd entirely on its way down to 2nd in the same situation.

So whatever. Feel free to insult me if it makes you feel better. You seem to enjoy doing that a lot to me. Did I do something to you to **** you off? Offend your delicate sensibilities? Let me know; I'll see what I can do to help ease your anguish.

That is entirely a function of the PCM firmware.

No, I just get irritated when people provide bad information, which has been happening a lot lately. You just happened to be in the middle of the most recent glaring examples. There's nothing wrong with not knowing an answer, but when in doubt either don't answer or qualify the answer, and certainly don't talk down to others heralding your qualifications when your very answer details your lack of understanding of the topic.

Do you have proof? Or corroborating evidence? Everything I've ever heard or read about is what I'm saying.

If that isn't the difference between a synchronous and non-synchronous transmission, then what the **** is? Why would you bother to use a non-S tranny?

Tell me o great master!

Sure do. All Ford PCM's programmed for 4-speed auto trannys where 4th gear is the overdrive gear will command 3rd gear in a 4-2 kickdown, even if 3rd gear is never actually engaged. You can see it in a datalog. This is a non-manipulable function of the PCM firmware. In the PCM calibration there is a scalar called "time_to_sequence_42_kickdown" which controls how much time, if any, the tranny spends in 3rd in between 4th and 2nd in a kickdown. Set that to zero as it is in the V8 cars and 3rd gear will never engage in a 4-2 kickdown even though you'll still see it commanded in a datalog. Similarly with upshifts, you can set the shift schedule to essentially skip gears regardless of whether you're dealing with an AX4S or AX4N.

Synchronous transmissions require two seperate actions to accomplish a gear shift; 1st gear disengages, then 2nd gear engages. Hopefully this all happens at the same time; thus the 'synchronous' part.

Non-synchronous transmissions require only one action to perform a shift

The selections I have quoted above are correct. It's all about improving efficiency and ameliorating wear & tear. That's why the AX4N/4F50N came to be. Again, it has nothing to do with sequential shifting.

This thread has outlived it's usefulness and is now closed.
