Transmission Fluid Inspection

Transmission fluid condition can provide many clues to the nature of the transmission concern. Proper transmission fluid level can only be determined with the transmission fluid at a specified temperature range. It is not necessary to verify exact transmission fluid level at this time. If the transmission fluid is below operating temperature, it is expected to be low on the transmission fluid level indicator. Transmission fluid temperatures below 30.2°F (-1°C) may not show up on a transmission fluid level indicator.

1. 1.
   
   With the vehicle in NEUTRAL, position it on a hoist. Refer to: Jacking and Lifting - Overview . Remove the transmission fluid fill plug and transmission fluid level indicator.

1. 2.
   
   Allow the transmission fluid to drip onto a facial tissue or white sheet of paper.

1. 3.
   
   Examine the stain.

1. 4.
   
   Small black particles are typically burnt friction material.

1. 5.
   
   Small shiny metallic particles indicate excessive hard part wear.

1. 6.
   
   Foamy pink color indicates either water or engine coolant in the transmission.
