-
NOTE: The Compressor, Forward Clutch Spring and the Compressor, Forward/Intermediate Spring not shown for clarity.NOTE: The snap ring gap should be at the top of the transmission case.
- Install the forward clutch wave spring.
- Soak the clutch plates.
Material: Clean Motorcraft® MERCON® LV Automatic Transmission Fluid XT-10-QLVC.
-
NOTE: The low OWC snap ring gap must be positioned as shown in illustration below so that the low/reverse clutch pressure plate tab fits into the gap when it is installed later in this procedure.
- Compare the position of the low OWC
snap ring gap with the tab on the low/reverse clutch pressure plate to be sure that the gap is in the right position.
- Rest the plunger on a top friction disc tab.
Special Tool(s): Dial Indicator Gauge with Holding Fixture 100-002 (TOOL-4201-C)
- New forward clutch feed seal.
- Apply 483 kPa (70 psi) of air pressure to the forward clutch piston port while recording the clutch pack clearance on the Dial Indicator. The clearance should be between 0.85 mm (0.033 in) and 2.41 mm (0.094 in). If the clearance is out of range, check the forward clutch pack and low OWC
for correct installation. If the forward clutch pack and low OWC
is correctly installed, install a new forward clutch pack.

- No. 11 stator support thrust bearing
- No. 10 front sun gear thrust bearing
- No. 8 front/center planetary gear assembly and the No. 7 center sun gear thrust bearings
-
NOTE: The groove on the center sun gear is installed facing up.
- No. 6 center sun gear and the No. 5 center/rear planetary thrust bearings
-
NOTE: Failure to align the tab on the bottom of the low/reverse pressure plate with the gap in the low OWC snap ring may result in damage to the transmission.
- Measure the depth of the low/reverse clutch pressure plate where the tab fits into the gap of the low OWC
snap ring and directly across from it. If the pressure plate is seated correctly, the depth should be the same. If the depths are different, rotate the snap ring so that the gap fits around the tab on the pressure plate.
- Soak the clutch plates.
Material: Clean Motorcraft® MERCON® LV Automatic Transmission Fluid XT-10-QLVC.
- Install the low/reverse clutch.
-
NOTE: The low/reverse clutch wave spring and pressure plate are temporarily reversely installed to measure the low/reverse clutch clearance.
Temporarily install the low/reverse clutch wave spring and pressure plate with the pressure plate on top of the wave spring.
- Using a straightedge and the Depth Micrometer 303-D075 (D92P-4201-A), measure and record as measurement A, the distance from the transmission case deck surface to the low/reverse pressure plate.
- Using the same straightedge and the Depth Micrometer 303-D075 (D92P-4201-A), measure and record as measurement B, the distance from the low/reverse clutch piston to the cover assembly deck surface.
- Subtract measurement B from measurement A and add 1.6 mm (0.062 in), to compensate for the thickness of the gasket, to get the low/reverse clutch clearance. The clearance should be between 0.83 mm (0.032 in) and 2.43 mm (0.095 in). If the clearance is out of range, check the low/reverse clutch pack for correct installation. If the low/reverse clutch pack is correctly installed, install a new low/reverse clutch pack.

NOTE: When the low/reverse clutch is correctly installed, the wave spring is on top.
- Install the intermediate clutch pressure plate.
- Soak the clutch plates.

- Using a straightedge and the Depth Micrometer 303-D075 (D92P-4201-A), measure and record as measurement A, the distance from the transmission case deck surface to a low point on the intermediate clutch wave spring.
- Using the straightedge and the Depth Micrometer 303-D075 (D92P-4201-A), measure and record as measurement B, the distance from the intermediate clutch piston to the cover assembly deck surface.
- Subtract measurement B from measurement A and add 1.6 mm (0.062 in), to compensate for the thickness of the gasket, to get the intermediate clutch clearance. The clearance should be between 0.99 mm (0.038 in) and 2.56 mm (0.1 in). If the clearance is out of range, check the intermediate clutch pack for correct installation. If the intermediate clutch pack is correctly installed, install a new intermediate clutch pack.

- Install the No. 1 thrust bearing on the overdrive/direct clutch assembly.
Shop Supplies: Petroleum Jelly.
- Position the overdrive/direct clutch assembly in the cover assembly, install the Dial Indicator Gauge with Holding Fixture 100-002 (TOOL-4201-C) plunger on the overdrive clutch pressure plate. Apply 483 kPa (70 psi) of air pressure to the overdrive clutch piston port while recording the clutch pack clearance on the Dial Indicator. The clearance should be between 1.13 mm (0.044 in) and 2.28 mm (0.089 in). If the clearance is out of range, check the overdrive clutch pack for correct installation. If the overdrive clutch pack is correctly installed, install a new overdrive clutch pack.
- Position the Dial Indicator Gauge with Holding Fixture 100-002 (TOOL-4201-C) on the direct clutch pressure plate. Apply 483 kPa (70 psi) of air pressure to the direct clutch piston port while recording the clutch pack clearance on the Dial Indicator. The clearance should be between 0.98 mm (0.038 in) and 2.34 mm (0.092 in). If the clearance is out of range, check the direct clutch pack for correct installation. If the direct clutch pack is correctly installed, install a new direct clutch pack.

NOTE: Be careful not to pinch the TSS , OSS or TR sensor wiring harnesses under the valve body, or damage to the wiring harness or connectors may occur.NOTE: Make sure that the manual pin (part of the TR sensor) is correctly installed in the manual valve.
-
NOTE: Make sure not to pinch the TSS , OSS or TR sensor wiring harnesses behind the solenoid body when positioning the solenoid body in place.
Hand-tighten only.
- Connect the TR
sensor electrical connector and slide the lock tab to the LOCK position.
- Check for damage.
-
NOTE: Install the studbolts in the correct locations as noted during disassembly.
-
NOTE: Only thread the bolts 6 to 8 turns or do not exceed 12 mm (0.472 in) in the torque converter. If the bolts are threaded too far, damage to the torque converter clutch surface can occur, causing torque converter failure.
Install two 10 mm x 1.50 bolts into the torque converter 6 to 8 turns to assist in handling the torque converter and install the torque converter in the transmission.
