What is different on this year and model

The 2020 Ford Explorer, being a redesigned model, features Ford's 10-speed automatic transmission (specifically the 10R60 or 10R80, depending on the engine). This sophisticated unit is designed for efficiency and smooth power delivery, but its complexity means it's highly sensitive to factors like fluid condition, software calibration, and sensor input. Early production models, or those with specific software versions, can sometimes exhibit shift quality issues that may be addressed by Ford through technical service bulletins (TSBs) or software updates. Unlike older, simpler transmissions, diagnosing issues with a 10-speed often requires specialized scan tools and up-to-date diagnostic procedures.

How to verify and confirm the issue

To accurately diagnose the source of your 2020 Ford Explorer's transmission jerking, a methodical approach is crucial:

• Observe driving conditions: Pay attention to when the harsh shifts occur. Is it only when cold, only when warm, at specific speeds, or during particular shifts (e.g., 1-2, 3-4)?
• Check transmission fluid level and condition: Park on a level surface with the engine warm and running (refer to your owner's manual for the exact procedure, as some transmissions require specific checks). The fluid should be at the correct level, reddish-pink, and clear. Dark, burnt-smelling, or cloudy fluid indicates a problem.
• Visual inspection for leaks: Look for any signs of transmission fluid leaks around the transmission pan, lines, and seals.
• Scan for diagnostic trouble codes (DTCs): Use an OBD-II scanner to check for any stored transmission-related codes (e.g., P07xx series, P17xx series). Even if the Check Engine Light isn't on, pending codes might be present. For more information on using a scanner, visit our Browse OBD-II codes section.
• Monitor live data: With an advanced scanner, monitor Transmission Control Module (TCM) live data parameters such as transmission fluid temperature, shift solenoid commands, input/output shaft speeds, and clutch pressures during a test drive. This can reveal erratic sensor readings or solenoid behavior.
• Check for Technical Service Bulletins (TSBs): Ford may have issued TSBs related to harsh shifting for the 2020 Explorer's 10-speed transmission. These bulletins often describe known issues and provide specific diagnostic and repair procedures, including software updates.

Common causes (most likely first)

The causes for 2020 Ford Explorer transmission jerking can range from simple to complex:

• Low or contaminated transmission fluid: The most common culprit. Incorrect fluid levels or degraded fluid can lead to poor hydraulic pressure and improper clutch engagement.
• Transmission Control Module (TCM) software issues: Outdated or corrupted software can cause the TCM to command incorrect shift points or pressures. Ford frequently releases updates to improve shift quality.
• Faulty shift solenoids: These electronic valves control the flow of fluid to engage different gears. A sticking or failing solenoid can cause harsh or delayed shifts.
• Internal transmission wear: Worn clutch packs, bands, or valve body components can lead to slipping and harsh engagement, especially in higher mileage vehicles.
• Input or output speed sensor failures: Incorrect speed readings can confuse the TCM, leading to erratic shifting.
• Mechatronic unit or valve body issues: The complex hydraulic control unit can develop issues, affecting pressure regulation and shift quality.
