CornLORD well Import Performance Transmissions can upgrade your AX4N trans and make it capable of 400hp if wanted.

The #4 is designed in for emissions. Tranny will not lock up until the fluid reaches some specific temp. Another poster checked the actual and got 100F. It makes the engine warm up faster and reach optimum efficiency.

I have 2 03's and one Lin Cont, none of the other issues. The Lincoln just shifts better period. Ford could have made the Bulls shift like the Lin but they chose to not.

And for the record, 4 speed shifts 3 times plus lockup. Under light throttle it might lockup in gear 3 in normal up to speed. Shift in gear 3 and it will lockup just fine, nice for towing. Never tow in gear 4 = OD.

2000CE
2000 CE AX4N on it's last legs

My 2000 CE is a sweet car the body and interior are amazingly clean
3.0L DOHC is strong, AX4N transmission is not as awesome.

Sometimes in the morning I will put car in gear and it takes 15-20 seconds before I get power to my wheels, it never shifts to OD while driving and if I slow to make a turn it acts like it is in neutral for a couple of seconds

I am faced with options of varying financial impact
Junkyard, $ cheap roll the dice option
Rebuild, $$ depends on shop / tech / day of week
Reman, $$$ most expensive option also longest warranty

Like some input from the members on how they have dealt with this.

FordMan82 I just went through this thread and just chiming in with my experience w/ my mother's 05 Vulcan.

We had the trans rebuilt last year at 90k, sheared the pump shaft w/o warning. It's got 96k on it now and just recently it started acting up with the 1-2 shift being jerky/hesitant at random. I've tried replicating it a few times I drove the car and managed to do it under light throttle. It also seemed to jerk when I did a 3-2 downshift with 3/4 ish throttle. Trans still has about another month or so under 1 yr warranty so I plan on taking it back to the place and have them diagnose. I've read about the VSS but I didn't notice the speedo do anything strange and it operates as usual when the symptoms occur.

Just want to add, we had recently acquired a used car from a small lot. The owner had a few 00+ Taurus/Sables on the lot and we talked a bit about them and I mentioned we had to do a rebuild on the trans of ours. He was surprised and told me he's sold dozens of them over the years ranging in mileage and not one ever had any transmission issues. Luck of the draw I suppose.

Yep, they really neutered it to give better economy numbers. CAFE and the stupid restrictions really irritate me given how efficient cars already are and how fast electric cars are approaching...

I switch to "D" when I get off the freeway for similar reasons. Lots of gradual slopes, and in lockup I have no power at all, and often it falls down to the lower gear anyway before I reach the top of the hill, which makes it pointless to begin with.

Dumping gears with so much impact will damage other internals, first to come in mind is the Torque Converter.

Another difference that I found is in gearing. My ex-Sable Duratec/AX4N '96 had a different gearing (different final drive), it was feeling more "sporty" in driving. The '01 Sable 4F50N jumps ASAP in 4th gear. Since the difference between the 3rd and 4th is very big in rpm's it feels more sluggish (compared with my ex '96).
AX4N Final Drive - 30T (95-up)
4F50N, Final Drive - 29T (01-up)
Yeah, I hate that lockup absolutely neuters power. Makes pulling onto the highway a chore unless you really goose it to prevent lockup until 60mph or so. If you leave it in regular "D", it pulls like its possessed. I merged onto a highway once and was wondering why I had so much power, forgot I left it in that gear, lol.

But yeah it probably wasn't normal. Mine shifts pretty smoothly 99% of the time. Sometimes you can feel the engagement being "slappy" is how I would describe it, but it never feels like an outright slam shift or shock.

The White Falcon Gearing was changed in '98, not '01. And the 94-95 AX4N's were geared like the AX4S as they were attached to a Vulcan.
