CAUTION: If the clutch plates or the intermediate band are replaced, soak the new parts in the specified automatic transmission fluid (ATF) for at least two hours before assembly. Apply the specified ATF to all seal rings, rotating parts, O-rings and sliding parts.
NOTE: Clean all bearings thoroughly in solvent and blow dry with compressed air. Inspect the bearings for pitting and rough operation. Replace as necessary.
NOTE: All O-rings, seals, and gaskets must be replaced with new ones.
Prior to installation, inspect the transmission case for damage, cracks, or wear. Replace as necessary.
Use (A) Valve Body Guide Pins to align the torque converter stator support. Use (B) Step Plate to press the (C) torque converter stator support into the converter housing.

CAUTION: The one-way clutch can be installed improperly. Be certain that after installing the one-way clutch, you can rotate the carrier by hand in a counterclockwise direction while working from the rear side of the transmission. If the one-way clutch is installed improperly, gear ranges may not function or the gear train may lock up. This may cause overheating of the transmission and unnecessary overhauling of the unit.
Install the one-way clutch horizontally. Use the rear sun gear to rotate the carrier counterclockwise while installing the one-way clutch.
Install the one-way clutch and one-way clutch retaining snap ring.
Adjust the servo piston stem.
Mark the servo piston stem at the point that it exits the transmission case.
Apply compressed air through the fluid passage. If the stroke exceeds 1.0 - 1.7 mm (0.0394 - 0.0669 inch) replace it with the appropriate length servo piston stem.
Servo Piston Stem Lengths

NOTE: If the clearance is greater than the specification, recheck/reassemble the clutch pack(s) as needed.
Measure the height difference between the reverse clutch drum and the transmission case.
NOTE: Use petroleum jelly to hold the thrust bearing in position.
Install the reverse clutch drum thrust bearing.
Set the thickest thrust washer, 2.2 mm (0.087 inch) onto the oil pump. Set the oil pump onto the forward/coast/reverse clutch drum assembly.
NOTE: Take several measurements and calculate the average value.
Use the following procedure to adjust the total end play and select a suitable bearing race.
Measure the clearance between the transmission case and the oil pump. Select a suitable thrust washer from the following chart:
Thrust Washer Chart
Remove the oil pump.
NOTE: Use petroleum jelly to hold the thrust washer in position.
Place the selected (A) thrust washer and a new (B) oil pump gasket onto the oil pump.
NOTE: Tighten the oil pump bolts evenly and gradually in a crosshatch pattern.
Install the oil pump onto the forward and reverse clutch drum assembly.
Install the (A) solenoid connector with a new O-ring in the transmission case, then connect the (B) solenoid electrical connector.
Position the main valve body to the transmission case. Align the (A) manual valve with the (B) pin on the manual valve detent lever.
NOTE: Tighten the main control valve body bolts evenly and gradually.
Install the main control valve body bolts and a new filter. Connect the solenoid electrical connectors.
Bolt length (measured from below the head) A: 30 mm (1.18 inch) .
C: 50 mm (1.97 inch) .
Install the EPC solenoid.
Install the EPC solenoid.
Install the bolt.
NOTE: Tighten the transmission oil pan bolts evenly and gradually.
NOTE: Apply a thin coat of Silicone Gasket and Sealant F6AZ-19562-AA or equivalent meeting Ford specification WSE-M4G323-A6 to each side of the new gasket.
Install the oil pan and new oil pan gasket.
Install the turbine shaft speed (TSS) sensor.
Install the sensor.
Install the bolt.
Install the vehicle speed sensor (VSS) .
Install the transmission range (TR) sensor.
Rotate the manual shaft to the N position.
Turn the TR sensor so that the Neutral mark is in line with the flat, straight surfaces on either side of the manual shaft.
Hand-tighten the TR sensor, then tighten the TR sensor mounting bolts.
Install the manual shaft lever.
Position the manual shaft lever.
Install the spring washer and manual control lever nut.
Install a new O-ring on the fluid filler tube, then install the fluid filler tube and dipstick assembly.
Install the fluid cooler line.
Install the check ball.
Install the drain back valve spring.

CAUTION: If a new torque converter is being installed or the torque converter has been drained and washed, pour 0.5L (0.53 qt.) of Motorcraft MERCON Multi-Purpose Automatic Transmission Fluid XT-2-QDX or equivalent meeting Ford specification MERCON into the torque converter before installation. Hold the torque converter in an erect position when filling it with Motorcraft MERCON Multi-Purpose Automatic Transmission Fluid XT-2-QDX or equivalent meeting Ford specification MERCON. MERCON (R) Automatic Transmission Fluid is being replaced by MERCON (R) V as a service fluid, as per TSB 06-14-4.
NOTE: The torque converter should slide into the transmission easily. Do not force the torque converter into the transmission.
Install the torque converter into the converter housing while rotating it to align the splines.
To ensure that the torque converter is installed properly, measure the distance between the torque converter and the edge of the converter housing.
Remove the transmission from Bench Mounted Holding Fixture.
