These transmissions use a combination of planetary gear sets, clutches, and bands, all controlled by hydraulic pressure and the Transmission Control Module (TCM). The TCM relies on various sensors to determine shift points and apply the correct amount of pressure. When any part of this intricate system falters, you’ll start to notice performance problems.
Common Symptoms of Transmission Trouble
Identifying the symptoms early is key to preventing minor issues from escalating. Pay close attention to how your Explorer feels and sounds during operation. Even subtle changes can be indicators of developing 2015 Ford Explorer transmission problems.
- Delayed or Harsh Shifting: The transmission might hesitate before engaging a gear, or shifts could feel unusually abrupt and jarring. This is often noticeable when going from park to drive or during upshifts and downshifts.
- Slipping Gears: You might feel the engine revving higher than usual without a corresponding increase in vehicle speed. This indicates that the transmission isn’t fully engaging the gear, causing power loss.
- Warning Lights: The “Check Engine Light” (CEL) or a dedicated transmission warning light on your dashboard is a clear sign that the vehicle’s computer has detected a fault.
- Unusual Noises: Whining, clunking, humming, or grinding sounds coming from the transmission area, especially during shifts or when in gear, are red flags.
- Fluid Leaks: Puddles or drips of reddish-brown fluid under your Explorer indicate a transmission fluid leak. Low fluid levels can quickly lead to severe damage.
- Burning Smell: A burnt odor, often resembling burnt toast, suggests overheating transmission fluid, which can break down and lose its lubricating properties.
- Limp Mode: The vehicle’s computer might put the transmission into “limp mode,” limiting power and speed to prevent further damage. This is a critical warning.
Pinpointing the Problem: DIY Diagnostics for Your Explorer
Before rushing to a mechanic, there are several diagnostic steps you can perform at home. These checks require basic tools and a bit of patience, offering valuable insights into what might be going wrong.
Checking Transmission Fluid Levels and Condition
This is often the first and most crucial step in diagnosing transmission issues. The 2015 Ford Explorer’s 6F transmissions are sealed units, meaning they don’t have a traditional dipstick. Checking the fluid requires a specific procedure.
- Warm Up the Engine: Drive your Explorer for about 15-20 minutes to bring the transmission fluid up to operating temperature.
- Park on Level Ground: Ensure the vehicle is parked on a perfectly level surface.
- Access the Fill Plug: With the engine running and the transmission in park, locate the transmission fluid fill plug. This is usually on the side of the transmission case. Consult your owner’s manual for its exact location and the correct procedure. You might need to remove an engine cover or airbox for access.
- Remove the Plug: Using the appropriate wrench (often a large Allen or Torx bit), carefully remove the fill plug.
- Observe Fluid Flow: If fluid immediately pours out, the level is likely correct or slightly overfilled. If no fluid comes out, the level is low. You might need a specialized dipstick tool (like the Ford 307-658) to get an accurate reading on some models.
- Check Fluid Condition: Drip some fluid onto a clean white paper towel. Healthy Mercon LV fluid should be reddish-pink and transparent. Dark, brownish, or black fluid, especially with a burnt smell or metallic particles, indicates significant wear or overheating.
Pro Tip: Always use the correct Mercon LV fluid for your 2015 Ford Explorer. Using the wrong type can cause immediate and severe damage to the transmission’s internal components.
