CARTRIDGE GP-TURBOCHARGER 1W3399 - Caterpillar

Transmission (Power Shift)
PROBLEM: Does not operate in any speed or does not engage (slips) in all speeds. PROBABLE CAUSE:1. Low oil pressure caused by: a. Low oil level.b. Control linkage loose or adjustment not correct.c. Failure of the oil pump or the pump drive.d. Air leaks on the inlet side of pump.e. Leakage inside the transmission.f. Load piston or differential valve operation not correct.g. Load piston not moving correctly.2. Mechanical failure in transmission.3. Failure of torque converter.4. Transfer gear, bevel pinion and/or bevel gear failure.5. Failure in steering clutches.6. Failure in final drives. PROBLEM: Transmission does not make a shift. PROBABLE CAUSE:1. Control linkage loose or adjustment not correct.2. Low oil level.3. Low clutch pressure. PROBLEM: Slow shifts. PROBABLE CAUSE:1. Low oil pressure.2. Adjustment of control linkage not correct.3. Air leaks on inlet side of pump.4. Load piston or differential valve will not move in pressure control valve. PROBLEM: Transmission is in a speed when the selector lever is in NEUTRAL. PROBABLE CAUSE:1. Control linkage loose or adjustment not correct.2. Direction clutch is engaged, and does not release. PROBLEM: Transmission operates in FORWARD speeds only. PROBABLE CAUSE:1. Control linkage loose or adjustment not correct.2. No. 1 clutch not engaged (slips) because of: a. Low oil pressure or leakage.b. Discs and plates have too much wear.c. Clutch has parts that are broken. PROBLEM: Transmission operates in REVERSE speeds only. PROBABLE CAUSE:1. Control linkage loose or adjustment not correct.2. No. 2 clutch not engaged (slips) because of: a. Low oil pressure or oil leakage.b. Discs and plates have too much wear.c. Direction clutch has parts that are broken. PROBLEM: Transmission does not operate in First Speed FORWARD or REVERSE. PROBABLE CAUSE:1. No. 5 clutch not engaged (slips) because of: a. Low oil pressure or leakage.b. Discs and plates have too much wear.c. Clutch has parts that are broken. PROBLEM: Transmission does not operate in Second Speed FORWARD or REVERSE. PROBABLE CAUSE:1. No. 4 clutch not engaged (slips) because of: a. Low oil pressure or leakage.b. Discs and plates have too much wear.c. Clutch has parts that are broken. PROBLEM: Transmission does not operate in Third Speed FORWARD or REVERSE. PROBABLE CAUSE:1. No. 3 clutch not engaged (slips) because of: a. Low oil pressure or leakage.b. Discs and plates have too much wear.c. Clutch has parts that are broken. PROBLEM: Pump noise not normal. PROBABLE CAUSE:1. Loud sounds at short intervals, that give an indication that particles are going through the pump, are caused by pump cavitation.2. A constant loud noise is an indication of pump failure.3. Air at the inlet side of pump (aeration). PROBLEM: Transmission engages but the machine does not move. PROBABLE CAUSE:1. Failure in final drives.2. Failure in steering clutches.3. Failure in bevel gear and pinion.4. Failure of drive shaft.5. Failure of transfer gears.6. Gears in the transmission will not move because of: a. Too many clutches are engaged.b. Mechanical failure in transmission.c. Mechanical failure in torque converter. PROBLEM: Transmission gets hot. PROBABLE CAUSE:1. Low oil level.2.
