How Do You Diagnose Ford Explorer Transmission Issues?

This will walk you through simple steps to identify transmission problems in your Ford Explorer, from basic inspections to advanced diagnostics. Follow this and you can fix minor issues before they become major.

What is a Transmission?

The transmission is one of the most critical parts of your Ford Explorer, it delivers the engine power to the wheels. This system allows your vehicle to shift gears smoothly, so you can accelerate and decelerate. In simple terms, it’s a bridge between the engine and the wheels, so the right amount of power goes to the wheels based on your speed.

Ford Explorers can have 2 types of transmissions:

1. Automatic Transmission – Shifts gears automatically based on speed and load, no need to shift gears manually.
2. Manual Transmission – Drivers can control gear shifts manually using a clutch pedal and gear lever, although this is less common in newer Explorer models.

Some Signs of Transmission Problems

Recognizing early signs of transmission trouble can prevent bigger repairs down the road. Here are some common signs Ford Explorer owners should look out for:

• Delayed or Rough Shifting: If you feel hesitation or a jerk when shifting gears, this could be wear and tear on the transmission. Rough shifting can also be low or dirty transmission fluid which affects performance.
• Slipping Gears: When your Explorer’s transmission slips out of gear or won’t stay in gear it may feel like a loss of power. This is often low transmission fluid, worn-out clutch plates, or a failing torque converter.
• Strange Noises: Grinding, whining or humming sounds coming from under the hood when shifting gears or accelerating means potential transmission problems. These noises mean worn or damaged internal parts.
• Burning Smells: A burning smell while driving means overheating transmission fluid. This is when fluid levels are low or the fluid is old and dirty, it can’t lubricate and cool the transmission.
• Transmission Fluid Leaks: If you see red or brown spots on your driveway, this means your transmission fluid is leaking. Low fluid levels can cause overheating and poor performance, so you need to address this ASAP.

Transmission problems can be minor or major, but recognizing these signs early can save you money and extend the life of your Ford Explorer’s transmission.

Common Causes of Transmission Issues in Ford Explorer

Ford Explorer transmission problems can be caused by many factors, most of which are wear, fluid issues, sensor failure, or clutch components. Here are the common causes.

1. Wear and Tear

As a vehicle ages or gets high mileage the transmission wears out. Parts inside the transmission like gears and seals experience friction over time which affects performance. Consistent wear can cause slipping, delayed shifting, or unexpected noise, especially in high-mileage Explorers.

2. Transmission Fluid Problems

Transmission fluid is the lifeblood of the transmission. Common fluid-related problems are:

• Low Fluid Levels: Low fluid can cause overheating and damage to components.
• Dirty Fluid: When fluid gets dirty it loses its lubricating ability and wears out parts.
• Wrong Fluid Type: Using the wrong type of fluid can disrupt transmission function and cause problems. Ford recommends specific fluids for optimal performance.

3. Electronic Sensor Failures

Ford Explorers with automatic transmission rely on sensors to control shifting and gear selection. A faulty sensor can confuse the system and cause improper or delayed shifts. Sensors monitor critical functions so a failure can cause shifting problems or even limp mode which limits the vehicle’s capability.

4. Clutch Problems (Manual Transmissions)

In manual Explorers, clutch problems are common, especially with frequent or aggressive shifting. Clutch-related problems are:

• Worn-out Clutch Disc: A worn-out clutch disc can’t engage smoothly making shifting difficult.
• Faulty Clutch Master or Slave Cylinder: These components control the hydraulic system that moves the clutch and any failure can affect performance.

Addressing these problems ASAP can save you from more costly repairs and keep your Explorer running smoothly.

Neglecting transmission maintenance often leads to costly repairs down the road. Regular checks on fluid levels, clutch wear, and electronic sensors can save you from major breakdowns.

Step-by-Step Guide: How to Diagnose Ford Explorer Transmission Issues

Diagnosing transmission problems in your Ford Explorer can be done methodically. Here’s a step-by-step guide to help you through it.

Step 1: Check the Transmission Fluid Level

• Find the Dipstick: Look for the transmission dipstick near the engine bay. Make sure the vehicle is on level ground and the engine is warm.
• Check Fluid Condition: Pull out the dipstick, wipe it clean, and reinsert it. Look at the color and smell:
  • Color: Healthy fluid is pink or red. If it’s dark brown or black it’s burnt.
  • Smell: Burnt smell means overheating or internal damage.
• Fluid Level: The level should be between the “Full” and “Add” marks. A low level means there’s a leak.

Step 2: Inspect for Transmission Fluid Leaks

• Common Leak Points: Check the transmission pan, seals, and gaskets. Fluid will pool under the vehicle if there’s a leak.
• Fluid on the Ground: Transmission fluid is red or pink. If you see this under your vehicle it’s a leak.

Step 3: Listen for Strange Noises

• Whining Sounds: Means fluid circulation or internal wear.
• Clunking Sounds: Worn or damaged transmission parts.
• Grinding or Buzzing: May suggest issues with gears or bearings.

Step 4: Perform a Transmission Control Module (TCM) Check

• Using a Code Reader: Connect a code reader to your vehicle’s OBD-II port to read error codes from the TCM.
• Common Error Codes: Look for codes like P0700 (Transmission Control System) or P0730 (Incorrect Gear Ratio) which are common in Ford Explorers and will guide you to the specific problem.

Step 5: Test Drive the Vehicle

• During the Drive: Listen for delayed shifting, slipping gears or hesitation.
• Specific Driving Maneuvers: Accelerate smoothly, then decelerate and turn to feel for unusual shifts or noises.

Step 6: Seek Professional Diagnostic Testing

• When to Get Help: If problems persist, get a professional mechanic to do the diagnostics.
• VIN-Specific Diagnosis: Using OEM Service Manua ldata specific to your vehicle’s VIN will give you accurate diagnosis and repair steps.

These steps will help you diagnose potential transmission problems in your Ford Explorer and catch them early to extend the life of your vehicle.

Tips for Preventing Transmission Issues

Taking care of your transmission proactively will reduce the chances of problems in your Ford Explorer. Here are some tips to keep your transmission in good shape.

Routine Maintenance

• Regular Fluid Checks: Transmission fluid is a lubricant and coolant. Check fluid levels monthly and top up if needed. Low fluid levels can cause overheating and friction and costly repairs.
• Timely Fluid Replacement: Follow the recommended schedule for fluid replacement, usually every 30,000 to 60,000 miles. Fresh fluid means smooth shifting and less internal wear.

Driving Habits

• Don’t Accelerate Rapidly: Quick starts and stops put extra stress on the transmission, and wears it out faster. Accelerate smoothly to extend the life of your transmission.
• Don’t Overload: Overloading the vehicle or towing heavy trailers can stress the transmission. Keep loads within the vehicle’s limits to prevent overheating.

Following OEM Guidelines

• Use Recommended Transmission Fluid: OEM guidelines will tell you what type of transmission fluid is recommended for your Ford Explorer. Using the right fluid will improve performance and protect internal parts.
• Follow Maintenance Schedules: Servicing according to OEM schedule will help you detect wear early and small problems won’t become big ones.

These simple steps will help you keep your transmission in good shape and avoid unexpected breakdowns and costly repairs.
