Transmission Fluid Inspection

WARNING: This page is about a different variant/trim than selected.

Transmission fluid condition can provide many clues to the nature of the transmission concern. Proper transmission fluid level can only be determined by following the Transmission Fluid Level Check Procedure.

  1. With the vehicle in NEUTRAL, position it on a hoist. REFER to: Jacking and Lifting - Overview . Remove the transmission fluid leveling plug.
  2. Allow the transmission fluid to drip onto a facial tissue or white sheet of paper.
  3. Examine the stain.

    • Small black particles are typically burnt friction material.

    • Small shiny metallic particles indicate excessive hard part wear.

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

  4. Set the transmission fluid level. REFER to: Transmission Fluid Level Check .
