notice a couple of hundred RPM Drop in the tach when the lock up
happens. If your NOT locking up, it generates a LOT more heat
which can translate into lower trannie life

The other issue on some tauri TC is Lock Out. That is when the TC spines
strip out and the non couped converter "locks you out" from driving
the car. Sometimes when the car is a no gears condition, you don't
necessarily need a new trannie, just a new TC. Its good to know this
before some shop tells you, you need a new trannie when you don't
And, IIRC, the spline issue is most prevalent on 2003 AX4N transaxles, though any can suffer it.

Ben Mine seemed to not want to go past 108. I'll try it again sometime.

Weird. What was your top speed again? I feel like mine should be close to yours being a 4.5 'Tec also.

Mark Oreman Ahh I see what i did. Whoops

I mean the torque lockup adds a technical 5th gear, not overdrive.

well 4 1/2 gears anyway.

No that i feel stupid I shall continue to pretend nothing has happened

The White Falcon The only issue with the description it that that's for the Gen 3's with the O/D Off button. On newer or AX4S models, OD is for all four gears, and D is for the first three.

Mark Oreman Drive This position provides all automatic shifts for first through fourth gears. This position also provides apply and release of the torque converter clutch (TCC). Coast braking occurs in third gear.
Fourth (OD) gear can be removed from the shift schedule by depressing the transmission control switch (TCS) on the transaxle range selector lever. Shift schedule status is displayed on the instrument cluster by the transmission control indicator lamp (TCIL) below the tachometer. If the TCIL display reads "O/D OFF", overdrive has been removed from the shift schedule and is not available. Depressing the TCS a second time restores overdrive to the shift schedule.

AX4N Automatic Transaxle, Description


4 speed with final clutch lockup - watch the RPM guage. I just did this too in my car and it was 4 gears + the clutch engagement.
