Frequent Transmission Problems Reported by 2022 Toyota Highlander Owners

While the 2022 Toyota Highlander is generally regarded for its reliability, some owners have reported specific transmission-related issues. Below are the common symptoms, diagnostic steps, and potential fixes for these problems.

Common Symptoms

Delayed Shifting: Hesitation or delay when shifting from park to drive or reverse.
Rough Shifting: Noticeable jarring during gear changes.
Slipping Gears: The vehicle unexpectedly shifts out of gear while driving.
Warning Lights: Transmission warning light illuminated on the dashboard.
Fluid Leaks: Puddles or spots of reddish fluid under the vehicle.
Unusual Noises: Grinding or whining sounds when changing gears.

Step 1: Check for Diagnostic Trouble Codes (DTCs)

Tools Required: OBD-II Scanner

Connect the OBD-II scanner to the vehicle’s diagnostic port (usually located under the dashboard).
Turn the ignition to the "On" position without starting the engine.
Read any trouble codes related to the transmission. Common codes might include P0715 (Transmission Fluid Temperature Sensor Circuit), P0730 (Incorrect Gear Ratio), etc.

Step 2: Inspect Transmission Fluid

Tools Required: Transmission dipstick (if applicable), fluid catch pan, funnel, and transmission fluid.

With the engine running and the vehicle in park, locate the transmission dipstick.
Pull out the dipstick and check the fluid level. It should be within the marked range.
Inspect the fluid color and smell. Healthy transmission fluid is typically a bright red color and does not have a burnt smell.
If low, add the appropriate transmission fluid as specified in the owner’s manual.

Step 3: Check for Leaks

Tools Required: Clean rag, flashlight.

Inspect the area around the transmission pan, seals, and lines for any signs of fluid leak.
Use a clean rag to wipe any suspected areas and check for fresh fluid accumulation.

Step 4: Test Drive the Vehicle

Take the vehicle for a test drive under various conditions (stop-and-go traffic, highway speeds).
Pay attention to any unusual sounds, shifting patterns, or warning lights.

Repair Instructions

Repairing Delayed or Rough Shifting

Transmission Fluid Change:
- Drain the old fluid using a fluid pump and catch pan.
- Replace the transmission filter if applicable.
- Refill with new transmission fluid as specified in the owner’s manual.
Adjust Transmission Control Module (TCM):
- If the vehicle has an adaptive transmission, reset the TCM by disconnecting the battery for about 30 minutes.
- Reconnect and allow the vehicle to relearn driving patterns.

Addressing Slipping Gears

Inspect and Replace Transmission Filter:
- If the filter is clogged, it can restrict fluid flow, causing slipping. Replace the filter as per the service manual.
Transmission Rebuild or Replacement:
- If slipping persists after fluid and filter replacement, consider professional evaluation as internal issues may require a rebuild or replacement.

Fixing Fluid Leaks

Replace Gasket or Seal:
- If leaks are found at the transmission pan or seals, replace the gasket or seals as needed.
- Clean the surfaces, apply a thin layer of RTV silicone if applicable, and reinstall the pan or seal.

Conclusion

While the 2022 Toyota Highlander generally has a reliable transmission, issues can arise. Following the diagnostic steps and repair instructions can help address common problems. Always refer to the service manual for specific torque specifications and procedures unique to your model. If issues persist, consult a professional technician for further assistance.
