What is different on this year and model

The 2020 Ford Explorer utilizes the advanced 10R60 or 10R80 10-speed automatic transmission, a complex unit designed for efficiency and smooth operation. Unlike older transmissions, these modern units rely heavily on electronic controls, numerous solenoids, and precise fluid pressure management. This complexity means that issues often stem from software glitches, sensor malfunctions, or valve body problems rather than purely mechanical failures in the initial stages. Ford has released various Technical Service Bulletins (TSBs) for these transmissions, often addressing shift quality concerns through software updates, highlighting the electronic nature of many common complaints.

Symptoms and warning signs

Beyond the primary issues of slipping and harsh shifts, keep an eye out for these additional indicators that your 2020 Explorer's transmission might be in distress:

• Check Engine Light (CEL) or Transmission Warning Light: The dashboard warning lights may illuminate, indicating a detected fault within the powertrain or transmission system.
• Reduced fuel economy: A struggling transmission can cause the engine to work harder, leading to decreased gas mileage.
• Burning smell: A distinct odor, often like burning toast, can indicate overheated transmission fluid or friction material.
• Fluid leaks: Puddles or drips under the vehicle, especially reddish-brown fluid, suggest a leak from the transmission or cooler lines.
• Difficulty shifting manually: If your Explorer has a manual shift mode, you might notice issues when attempting to change gears yourself.

How to verify and confirm the issue

Confirming a transmission issue in your 2020 Ford Explorer involves a combination of driver observation and diagnostic checks:

• Test Drive Observation: Pay close attention to RPMs, shift points, and vehicle behavior during various driving conditions (city, highway, light acceleration, heavy acceleration). Note specific gears where issues occur.
• Transmission Fluid Check: Park on level ground, warm up the engine, and check the transmission fluid level and condition (color, smell). Low fluid is a common cause of shifting problems. Burnt-smelling or dark, gritty fluid indicates internal wear.
• Scan Tool Diagnosis: Use an OBD-II scanner to check for Diagnostic Trouble Codes (DTCs). Look for transmission-specific codes (e.g., P07xx, P17xx). Advanced scanners can also monitor live data such as transmission fluid temperature, shift solenoid activity, and gear commanded vs. actual gear, which can pinpoint electronic control issues.
• Research Technical Service Bulletins (TSBs): Check if Ford has issued any TSBs related to transmission shift quality for the 2020 Explorer's 10-speed transmission. Many issues are resolved with software updates or minor component replacements outlined in TSBs.
• Listen for Noises: With the vehicle safely supported, listen for unusual noises when shifting between Park, Reverse, and Drive, or during a slow test drive.

Common causes (most likely first)

Addressing transmission problems in your 2020 Ford Explorer often starts with the most common and least invasive causes:

• Low or Contaminated Transmission Fluid: The 10-speed transmission is highly sensitive to correct fluid levels and quality. Old, dirty, or low fluid can cause pressure issues, leading to slips and harsh shifts.
• Software Glitches or Outdated Calibration: As mentioned, electronic control is paramount. Ford frequently releases software updates to improve shift logic and address known issues. An outdated Transmission Control Module (TCM) calibration can cause erratic behavior.
• Faulty Shift Solenoids: These electronic valves control fluid flow to engage different gears. A failing solenoid can cause delayed, harsh, or missed shifts.
• Transmission Control Module (TCM) Issues: The TCM, either integrated into the Powertrain Control Module (PCM) or a standalone unit, can malfunction, sending incorrect signals to the transmission.
• Valve Body Problems: The valve body directs hydraulic fluid to the clutches and bands. Wear or blockages in the valve body can lead to inconsistent pressure and poor shift quality.
• Internal Mechanical Wear: Over time, clutch packs, bands, or other internal components can wear out, leading to slipping. This is generally less common in newer vehicles like the 2020 Explorer unless subjected to severe use or lack of maintenance.
• Torque Converter Issues: A failing torque converter can cause slipping, shuddering, or overheating.
