DISASSEMBLY AND ASSEMBLY OF SUBASSEMBLIES
Torque Converter One-
Way Clutch Check
1. Install the special tool in one of the grooves in the stator thrust washer.
2. Install the special tool in the converter pump drive.
3. Use a torque wrench to turn the special tool counterclockwise while holding the special tool stationary.
zThe converter should lock up and hold torque.
z The torque converter one- way clutch should rotate freely in the clockwise direction.
z Try the clutch for lockup and hold in at least five positions.

DISASSEMBLY AND ASSEMBLY OF SUBASSEMBLIES
Torque Converter Turbine to Pump Stator Interference
Check
1. NOTE: Front pump support may remain in front pump support and gear during this test.
Position the torque converter with the pump drive up.
2. Install the front pump support to engage the mating splines of the front pump support shaft on the torque converter.
3. Install the forward clutch cylinder and shaft, engaging the splines with the rear clutch hub.
4. Check for stator to turbine interference. 1. Hold the front pump support stationary.
2. Attempt to rotate the forward clutch cylinder and shaft.
„The turbine and torque converter clutch assemblies should rotate in both
directions, not exceeding maximum torque of 9.5 Nm (7 lb- ft), without any signs of
metallic interference or scraping noise.
5. If interference exists, the stator front thrust washer may be worn, allowing the stator to hit the turbine. In such cases, a new or remanufactured torque converter must be installed.
zThe converter crankshaft pilot should be checked for nicks or damaged surfaces that
could cause interference when installing the torque converter into the crankshaft. Check
the converter front impeller hub for nicks or sharp edges that would damage the pump
seal.

CAUTION: Before beginning assembly, carry out and inspect the following:
When building up subassemblies and assembling the transmission, ALWAYS use new gaskets
and seals.
All fasteners must be tightened to the torque specification indicated. In addition to appearing in
the section, the necessary torques can be found in the General Specifications Chart.
When building up subassemblies, each component part should be lubricated with clean
transmission fluid. It is also good practice to lubricate the subassemblies as they are installed
in the case.
Needle bearings, thrust washers and seals should be lightly coated with petroleum jelly during
subassembly buildup or transmission assembly.
Many components and surfaces in the transmission are precision machined. Careful handling
during disassembly, cleaning, inspection and assembly can prevent unnecessary damage to
machined surfaces.
1. Use the special tools to install the rear case bushing if removed. 1. Position the rear case bushing and the special tool inside the case.
2. Assemble the special tools through the back of the case.
2. Place the transmission in the vertical position.
3. Coat the No. 9 case rear bearing with petroleum jelly and install on the case boss.
4. CAUTION: Be sure the No. 7 needle bearing and direct clutch hub are installed as
shown in the Subassembly section. Internal damage and shift problems may occur. D0AZ-

23.
NOTE: Before assembly, soak the new clutch discs in clean automatic transmission fluid for 15
minutes.
Install the intermediate clutch pack and selective steel plate.
24. Using the special tool, check the intermediate clutch clearance. 1. Position the special tool on the pump case mounting surface.
2. Maintaining downward pressure, use a depth micrometer to measure and verify intermediate clutch clearance is within specification.
If the intermediate clutch is not within specification, install a correct selective plate.
25. Install the intermediate anti- rattle clip, if equipped. Selective Steel Plates

68. Lightly lubricate the converter hub with clean automatic transmission fluid.
69.
WARNING: The torque converter can fall out if the transmission is tipped.
CAUTION: Make sure the converter hub is fully engaged in the front pump support
and gear and rotates freely. Do not damage the hub seal.
CAUTION: If the torque converter slides out, the hub seal may be damaged.
Using the special tools, install the torque converter.
