TERMINAL 2196208 - Caterpillar

Torque Converter
PROBLEM: Torque converter gets hot (pointer of converter oil temperature gauge in red area). PROBABLE CAUSE:1. Low oil level in transfer gear case.2. Low water level in engine radiator.3. Restrictions in oil cooler or oil lines.4. Too much operation of machine at or near stall speed (overload).5. Bad temperature gauge.6. Too much oil in the converter housing around the converter because of: a. Too much oil leakage inside the converter.b. Pressure inlet valve for converter does not move (too much inlet oil).7. Not enough oil to the converter because of: a. Pressure inlet valve for converter does not move (not enough inlet oil).b. Oil pump failure.c. Too much leakage in transmission. PROBLEM: Full torque indicator light does not come "ON" when the torque converter solenoid switch is pushed to "ON." PROBABLE CAUSE:1. Bad bulb.2. Bad fuse.3. Failure in the wiring of converter solenoid and switch circuit. PROBLEM: High pressure at converter outlet relief valve tap. PROBABLE CAUSE:1. Adjustment of converter outlet relief valve not correct.2. Valve spool in outlet relief valve does not move. PROBLEM: High pressure at converter clutch pressure tap (wheel torque lever in "MINIMUM" position). PROBABLE CAUSE:1. Adjustment of converter control linkage not correct.2. Initial pressure setting of pressure control valve not correct.3. Converter hand switch activated. PROBLEM: Low pressure at converter clutch pressure tap (wheel torque lever in "MINIMUM" position). PROBABLE CAUSE:1. Initial pressure setting of pressure control valve not correct.2. Too much leakage in converter clutch. PROBLEM: High pressure at converter clutch pressure tap (wheel torque lever in "MAXIMUM" position). PROBABLE CAUSE:1. Operation of pressure control valve not correct.2. Operation of modulation relief valve not correct. PROBLEM: Low pressure at converter clutch pressure tap (wheel torque lever in "MAXIMUM" position). PROBABLE CAUSE:1. Adjustment of converter control linkage not correct.2. Operation of pressure control valve not correct.3. Operation of modulation relief valve not correct.4. Too much leakage in converter clutch. PROBLEM: Low pressure at converter clutch pressure tap (hand switch activated). PROBABLE CAUSE:1. Failure of converter solenoid.2. Failure in the wiring of converter solenoid and switch circuit.3. Too much leakage in converter clutch.4. Operation of pressure control valve not correct. PROBLEM: High pressure at converter clutch pressure tap (hand switch activated). PROBABLE CAUSE:1. Operation of modulation relief valve not correct.2. Operation of pressure control valve not correct.
