FORD AX4S/AX4N - Tcc Solenoid Change And Shift Solenoid Interchange

(UPDATED INFORMATION)
CHANGE: At the start of production for the 1997 model year, the Lincoln Continental equipped with the AX4N transaxle, received a new design and higher resistance,  Modulated Lock-Up Solenoid. Know more obd2 scanner?
At the start of production for the 1998 model year, the Taurus and Sable equipped with the AX4S transaxle, also received this new design Modulated Lock-Up Solenoid (MLUS).

REASON: Much improved converter clutch application and durability.

PARTS AFFECTED:
(1) MODULATED LOCK-UP SOLENOID - The new design MLUS is round, like the previous design solenoid, but has a blue connector instead of the previous white, and a resistance value of 13-24 Ohms, instead of the previous 0.98-1.6 Ohms resistance (See Figure 1).

INTERCHANGEABILITY:
The O.E. Manufacturer first advised not to interchange the solenoids, but has since backed off of that statement, as the only MLUS now available is the new design with the blue connector and higher resistance. ATSG has seen no problems with installing the new design MLUS on the previous model transaxles, except 1991 Taurus and Sable which are non-modulated models. Use the chart in Figure 2 to check the resistance of the MLUS through the case connector to determine which solenoid is in the transaxle.
SPECIAL NOTE:
Shift Solenoids - Shift Solenoids for the AX4S transaxle and AX4N transaxle are identical in every dimension and every respect except one.  Shift Solenoids for the AX4S have a diode in the solenoid, and Shift Solenoids for the AX4N do not have a diode in the solenoid, as the vehicles equipped with the AX4N have the diodes in the processor.Some car tools such as OPEL EDC16 KM Tool and BMW and BENZ Scanner are helpful to you.
This means that the AX4S Shift Solenoids can be used in AX4N transaxles, but AX4N Shift Solenoids cannot be used in AX4S transaxles, as there would be no diode protection. Most suppliers stock only the AX4S shift solenoid, as it works well on both.
