Transmission Fluid Check

2010 Mercury Mariner Hybrid, AWDSECTION Transmission Fluid Check
WARNING: This page is about a different variant/trim than selected.
NOTE: The transmission fluid should be checked at normal operating temperature 85°C-93°C (185°F-200°F) on a level surface. Normal operating temperature can be reached after approximately 32 km (20 mi) of driving and can be checked using the scan tool.

Under normal circumstances the transmission fluid level should be checked during normal maintenance. If the transaxle starts to slip, shifts slowly or shows signs of transmission fluid leaking, the transmission fluid level should be checked.

  1. With the selector lever in PARK, the engine at idle, foot pressed on the brake, move the selector lever through each gear and allow engagement of each gear. Place the selector lever in the PARK position.
  2. Wipe the transmission fluid level indicator cap and remove the transmission fluid level indicator.
  3. Wipe the transmission fluid level indicator with a clean cloth.
  4. Install the transmission fluid level indicator back in the transaxle filler tube until it is fully seated, then remove the transmission fluid level indicator. The transmission fluid level should be within the crosshatch.
