The transmission fluid noticed in the top pockets of the transmission assembly may be fluid that was not thoroughly cleaned during assembly. The remaining fluid may now by seen underneath the vehicle and may be mistaken as a fluid leak.

Clean any transmission fluid on the transmission assembly. Also inspect the transmission fluid level and adjust the fluid to the correct level as needed.

To check for any leaks, install dye into the transmission and road test for a minimum of 15 minutes to ensure that the transmission fluid reaches operating temperature. After the road test, use a black light to inspect for any visual signs of the dye.

If dye is detected, follow the appropriate Service Information to make any repairs.

If dye is not detected, no further repairs are needed.
