What type fluid does an AX4N transmission use?
No one knows, its written on the transmission dip stick I read somewhere that 98 and newer had V which is synthetic but Pre have ATF because mercon does not exist, but it needs Mercon M what ever that correlates too which is nothing, so the answer is a crap shoot, V probably works fine, but the transmission sucks so i wonder if thats why they started using synthetic you can tell by smell I used V and it Smells awful like dead fish, what ever is inside did not smell like V. SO i do not recomend V anyway good luck if you find out let me know because no one knows.
How many quarts of transmission fluid do you need to put in a Generation 3 Ford Taurus or Mercury Sable?
(This answer Covers the "Generation 3" 1996-1999 Series Ford Motor Company Ford Taurus and Mercury Sable.) This answer differentiates depending on the transmission and the engine equipped. Normally the 1998+ year model Taurus/Sables had the AX4N Transaxle, whereas the 1996-1997 models had the AX4S. However due to transmission replacements and "one-off's" at the factory, many 1996+ Model tauri were shipped with the AX4N transaxle and some 1998+ models had the AX4S. To determine which transmission…
All AX4S/AX4N Transmissions currently use MERCON V automatic transmission fluid. The previous specification was MERCON ATF but Ford recently released a Technical Service Bulletin stating that all MERCON ATF fluid would be replaced with MERCON V ATF as MERCON V ATF supersedes MERCON ATF specifications. The fluid you must use in Ford Taurus Power Steering Systems and Automatic Transmissions are now MERCON V Automatic Transmission Fluid.
The shifting in the AXOD is done with fluid accumulators. Fluid fills the accumulator and pushes on a piston until it bottoms out. During that time, the clutches are applying slowly. In and AXODE or the AX4N, they eliminate the accumulators and use electric solenoids that regulate pressure to the clutch pistons. These transmissions are NOT interchangeable.
