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

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.

what i notice about my AX4N is this:
1 bangs on reverse
2 it doesn't like high revs then jerks when shifting
3 even though it's a 4 speed trany (which mean it supossed to shift 3 times) you'll feels the shift 4 time. Torque converter likes to lock up late like during low 3rd gear like for ex: 1st-2nd 2nd-3rd(low) 3rd(low)-3rd(high) 3rd-4th like this every time.
4O.D doesn't work when the tranny is cold
5: there a tiny groan when your drive first in the morning (usually after your have it parked for a bit)

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.

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.

|SoNic67||With the '96 I never felt the need for turning the "OD" off. With the '01, I drive daily trough a tunnel - on the "up" incline (it's loong) I am shifting in "D", because it is so annoying no to have 'umpf' - I have slow at bottom of ramp to moderate-high speed at top (I know, stupid people, that's how they drive, scared of being under water I guess) .|

|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.|

Maybe my kick it was the third to first or second... but I don't think is normal. I had another AX4N before and it didn't do it. Surely that one it still died at 200k miles
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)
