SYMPTOM CHART

Condition	Possible Sources	Action
The concern is unverifiable; no DTCs	The concern description is inaccurate.	GO to PINPOINT TEST A .
The transfer case makes noise	Tire inflation pressure. Tire and wheel size. Fluid level. Internal components.	MAKE SURE all tires and wheels are the same size and brand, and the inflation pressures are correct. FILL with the correct type and amount of lubricant. REFER to TRANSFER CASE-POWER TRANSFER UNIT (PTU) . OPERATE the vehicle in all transaxle gears. If there is noise in the transaxle in NEUTRAL, or in some gears and not in others, REMOVE and REPAIR the transaxle. REFER to AUTOMATIC TRANSAXLE-TRANSMISSION - CD4E for automatic transaxle, AUTOMATIC TRANSAXLE-TRANSMISSION - ELECTRONICALLY CONTROLLED CONTINUOUSLY VARIABLE TRANSMISSION (ECVT) for the electronically controlled continuously variable transmission (ECVT), or MANUAL TRANSAXLE-TRANSMISSION for manual transaxle. If there is noise in all gears, INSTALL a new transfer case. REFER to TRANSFER CASE-POWER TRANSFER UNIT (PTU) .
Leaking fluid from the transfer case vent	Transfer case. Vent tube.	DRAIN the fluid to the correct level. REFER to TRANSFER CASE-POWER TRANSFER UNIT (PTU) . REPAIR or INSTALL a new vent. REFER to TRANSFER CASE-POWER TRANSFER UNIT (PTU) .
Leaking automatic transmission fluid	Transfer case driven gear seal.	INSTALL a new transfer case driven gear seal. REFER to TRANSFER CASE-POWER TRANSFER UNIT (PTU) .
Leaking gear lubricant from the seals	The vent is plugged. Damaged seals.	INSTALL a new vent. REFER to TRANSFER CASE-POWER TRANSFER UNIT (PTU) . For automatic transaxle, INSTALL new seals. REFER to TRANSFER CASE-POWER TRANSFER UNIT (PTU) . For manual transaxle, INSTALL a new transfer case. REFER to TRANSFER CASE-POWER TRANSFER UNIT (PTU) .
