Mobil ATF™ 3309

Automatic transmission fluid designed to provide excellent lubrication in specified automatic transmissions

Mobil ATF 3309 is an exceptionally high performance lubricant that meets original equipment manufacturers’ specifications for use in certain slip-controlled, lock-up automatic transmissions.

The unique formulation of Mobil ATF 3309 is recommended by ExxonMobil for use in transmissions requiring fluids of JWS 3309 or GM 9986195 quality levels. It is also recommended for service fill applications where Toyota T-IV (T4) or T-III (T3) are called for. Please refer to the owner’s manual for proper fluid requirements.

Automatic transmissions should be checked for proper fluid levels at regular intervals, and the fluid should be changed at manufacturer-recommended intervals. However, this may vary due to your vehicle's operating conditions. Some manufacturers recommend more frequent changes of transmission fluid under severe driving conditions, such as heavy traffic, high ambient temperature and trailer pulling.
