  Q: How to service the LH differential seals and check the transmission fluid level on Lincoln MKZ?

  A: The initial step to service LH differential seals requires halfshaft removal from the LH side. A suitable dent puller should be used to extract the LH differential fluid seal after you make a small hole with a suitable awl through the seal. The new differential fluid seal goes in position first as you operate the Output Shaft Seal Installer to place the outer differential fluid seal before reattaching the LH halfshaft. To proceed with this operation set the transaxle to PARK position then place the vehicle on level ground while maintaining engine RPM at 680-780 above idle speed and keep your foot pressed on the brake. Operate the selector lever from position to position for gear engagement before placing it into the PARK setting. Before removing the transmission fluid level indicator cap you must clean it along with wiping the indicator with a fresh cloth. After setting the vehicle level with proper engine reaching 60°C-70°C (140°F-158°F), one can check the transmission fluid level accurately. To add fluid insert 0.25L through the fill plug positioned on top of the transaxle. The fluid amount should stop at the highest point of the indicator. When the transmission operates at its correct normal temperature range it should rest between the two highest marks on the indicator yet when the temperature falls to 59°F-77°F (15°C-25°C) the fluid level should be positioned at the base mark. Fill the transmission fluid to the cold range when TFT reading is under threshold but recheck the level when the transaxle achieves normal operating temperature. The procedure ends with reinstallation of the fill plug that requires tightening to 39 Nm (29 lb-ft).
