Info - Removal of Transmission Fluid Fill/Vent Cap During Transmission Fluid Checking Procedure

Notice: The fluid vent cap must be removed before checking the fluid level, in order to ensure the proper level. Improper fluid level may damage the transmission.

This bulletin is being issued to inform technicians that the transmission fluid fill/vent cap installed on the 4T45-E automatic transmission for the 2004 Chevrolet Malibu (new body style ONLY) MUST be removed any time the transmission fluid is checked. If the fluid fill/vent cap is not removed, an inaccurate fluid level reading will result which may lead to fluid overfill and unit damage.
