M/T - Fluid Recommendation/Caution

NO.: TSB-93-22-001
DATE: April, 1993
MODEL: All

SUBJECT:
MANUAL TRANSMISSION/TRANSAXLE GEAR OIL

PURPOSE

The manual transmissions/transaxles in Mitsubishi Motors vehicles require the use of API GL4 classification gear oil. Using an incorrect API classification gear oil may affect the shift effort and may cause transmission/transaxle component damage.

Use only gear oils having the API Classification GL4.

Mitsubishi Diamond Gear Lube - A991ZC2X01 - SAE 75W - 85W GL4, meets this requirement.

CAUTION:
Do not use gear oils having an API GL5 classification. GL5 oils have additives which may chemically react with sintered copper synchronizer rings leading to manual transmission/transaxle damage.
