SECTION 307-01: Automatic Transaxle/Transmission
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.
The 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.
