Some vehicles may experience an intermittent Neutral condition. This may be caused by the bonded seal on the forward clutch piston intermittently not sealing during the 3-2 downshift.
Replace the forward clutch piston with a revised Forward Clutch Piston (F8DZ-7A262-AB). Refer to the following SERVICE PROCEDURE for details.
Clean and reseal the transaxle completely including replacement of the forward clutch piston with revised forward clutch piston and replace the forward clutch plates if darkened or discolored from heat. Refer to the appropriate Continental Service Manual, Section 07-01, or the appropriate Taurus/Sable Service Manual, Section 07-01B, for details.
Be sure to check end clearance on all three (3) select fit thrust washers (#16, #8, #5) and clutch clearances (forward clutch clearance is 1.02 - 1.50mm (0.040 - 0.059")). Be sure to clean and inspect the main control (pump and valve body) and servos. Prior to returning vehicle to customer recheck fluid level at operating temperature.
