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-

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.
70. Lubricate the torque converter pilot hub with multi- purpose grease. Klj . 24 ba

INSTALLATION
Transmission
1. CAUTION: During this move, to avoid damage, do not allow the transmission to get
into a nose- down position as this will cause the torque converter to move forward and
disengage from the pump gear. The converter housing is piloted into position by dowels
in the rear of the engine block. The torque converter must rest squarely against the
flexplate. This indicates that the converter pilot is not binding in the engine crankshaft.
Position and secure the transmission on the high- lift transmission jack.
2. CAUTION: Make sure the torque converter is fully seated in the transmission before
positioning the transmission to the engine.
Using the special tool, install the transmission to the engine.
zAlign the orange balancing marks on the converter stud and the flexplate bolt hole. 3. Reconnect the harness. SECTION 307-

forces exerted by the clutch pressure plate and the flywheel on the facings. These factors limit
the amount of torque that can be transmitted without slippage.
z The clamping force is obtained from a diaphragm spring contained within the clutch pressure
plate assembly. This force is developed during the attachment of the clutch pressure plate
assembly to the flywheel.
z The clutch system is disengaged when the clutch pedal is pressed and is accomplished when
the release fingers are fully displaced toward the flywheel. This displacement removes the
spring load from the clutch pressure plate and eliminates the coupling friction between the
engine and the transmission.
z When the clutch pedal is depressed a cable connected to the clutch release lever, hub and
bearing actuates the clutch pressure plate diaphragm spring, releasing pressure on the clutch
disc. This eliminates the engagement between the transmission and the engine. Klj . 4 ba
