Ford Explorer Transmission Fluid Level

Q. Vincent, I have a 2002 Ford Explorer with a 4.6 liter V-8 and automatic transmission. I wanted to check the fluid level of the transmission and could not find the dip stick. Questioning the garage they said there wasn't one. How do you check the fluid level? Would you recommend switching to synthetics for all lubricants? If you do what do you recommend and how much gas mileage improvement do you think I should get?

Thanks,
Bob

A. What happened to the days when all you had to do to check the transmission fluid was start the engine and pull the transmission dipstick out? Are you ready for the fluid level and fill procedure? Here it is!

FLUID LEVEL CHECK (Fluid Fill Reference Figure 5)

  1. Using the scan tool (WDS), monitor the transmission fluid temperature (TFT) using PID: TFT.
  2. Start the vehicle.

NOTE: ENGINE IDLE SPEED IS APPROXIMATELY 650 RPM

  1. Run the engine until the transmission fluid temperature is between 80°F to 120°F.
  2. Move the range selector lever slowly through each gear, stopping in each position and allowing the transmission to engage.
  3. Place the range selector lever in the Park position.
  4. Raise and support the vehicle with the engine running. For additional information, refer to Workshop Manual Section 100-02.
  5. Place a suitable drain pan under the vehicle.
  6. With the transmission range selector lever in the Park position, hold the larger drain plug with a wrench and remove the small (center) fluid level indicating plug using a 3/16-inch Allen key (Figure 8).

  1. Allow the fluid to drain. Wait approximately 1 minute. When the fluid comes out as a thin stream or a drip, the fluid is at the correct level.
  2. If no fluid comes out of the hole, fluid will need to be added. Continue with this procedure.
  3. Install special tool 307-437 into the pan (Figure 10).

  1. Using special tool 303-D104, extract approximately 1 pint of clean automatic transmission fluid from a suitable container (Figure 11).
  2. Using the special tools, fill the transmission with clean automatic transmission fluid (Figure 12).
  3. Remove special tool 303-D104.
  4. Allow the fluid to drain. Wait approximately 1 minute. When the fluid comes out as a thin stream or drip, the fluid is at the correct level. If no fluid drains from the plug, keep adding fluid in ½-pint increments until the fluid starts to drain from the plug.
  5. Remove the special tool from the pan (Figure 10).
  6. Reinstall the small (center) fluid level indicating plug using a 3/16-inch Allen key. Torque to 89 lb-in (Figure 8).
  7. Lower the vehicle.
  8. Remove the WDS.
  9. Check the operation of the transmission by moving the range selector lever slowly through each gear, stopping in each position and allowing the transmission to engage.
  10. Raise and support the vehicle with the engine running and check for any leaks. For additional information, refer to Workshop Manual Section 100-02.
  11. Lower the vehicle and shut off the engine.
