how to fix Honda Civic 11th Generation (2022-Present) transmission slipping when shifting

Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, fluid catch pan, socket set, torque wrench, transmission fluid.
• Park the vehicle on a flat surface and engage the parking brake.
• Disconnect the battery to ensure safety while working on electrical components.

2. Check and Replace Transmission Fluid

1. Locate Transmission Dipstick: Remove the dipstick from the transmission (if applicable).
2. Check Fluid Level: Insert the dipstick back and remove it to check the fluid level. It should be within the marked range.
3. Inspect Fluid Condition: Observe the fluid color and smell. If it appears dark or smells burnt, it needs to be replaced.
4. Drain Fluid:
   • Place a fluid catch pan under the transmission pan.
   • Remove the transmission pan bolts using a socket set and allow fluid to drain completely.
5. Replace Fluid:
   • Install a new transmission filter if applicable.
   • Reinstall the transmission pan, tightening bolts to the manufacturer’s specified torque values.
   • Refill with new transmission fluid through the dipstick tube, using the recommended fluid type.

3. Inspect and Repair Transmission Components

1. Inspect Transmission Control Module (TCM):
   • Remove the TCM from its mounting location.
   • Check for corrosion or damage to connectors and wiring.
   • Replace TCM if faulty.
2. Check for Mechanical Issues:
   • Inspect internal components (clutches, bands, etc.) by removing the transmission if necessary.
   • Replace any worn or damaged parts as indicated by inspection.

4. Reconnect Battery and Test Drive

1. Reconnect the battery.
2. Start the engine and let it warm up.
3. Conduct a test drive to ensure the transmission shifts smoothly and does not slip.
