why does my Honda CR-V have a check transmission light on

Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, transmission fluid dipstick, funnel, transmission pressure gauge.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to prevent electrical shorts during repairs.

2. Check and Replace Transmission Fluid

• Sub-steps:
  1. Locate the transmission dipstick and remove it.
  2. Wipe the dipstick clean, then reinsert it to check the fluid level.
  3. If low, add the correct type of transmission fluid (refer to the owner's manual for specifications).
  4. If the fluid is dark or has a burnt smell, proceed to drain and replace the fluid.
  5. To drain, locate the transmission drain plug, remove it, and allow fluid to fully drain into a pan.
  6. Replace the drain plug and torque it to the manufacturer’s specifications.
  7. Refill the transmission with new fluid through the dipstick tube using a funnel.

3. Inspect and Repair Transmission Components

• Sub-steps:
  1. Remove any protective covers or shields to access the transmission assembly.
  2. Inspect the transmission for any damaged or worn components (e.g., bands, clutches).
  3. Check the condition of the transmission filter and replace it if necessary.
  4. Reconnect any damaged electrical connectors and repair wiring if needed.
  5. Reassemble any covers or shields removed during inspection.

4. Clear Error Codes

• Sub-steps:
  1. Reconnect the battery.
  2. Use the OBD-II scanner to clear any stored error codes from the vehicle’s computer.
  3. Turn on the ignition and check that the check transmission light is no longer illuminated.
