2. Check and Replace Transmission Fluid

• Sub-steps:
  • Remove the transmission fluid dipstick and check fluid level; add fluid if low.
  • If fluid is dark or has a burnt smell, drain the transmission fluid using a wrench.
  • Replace the transmission fluid with the manufacturer-recommended type (e.g., Honda ATF DW-1).
  • Refill the transmission with new fluid and ensure the level is correct.

3. Inspect and Repair Wiring/Connectors

  • Repair or replace any damaged wires or connectors.
  • Ensure all connections are secure.

4. Replace Transmission Filter

• Sub-steps:
  • Remove the transmission pan using a socket set, allowing fluid to drain into a container.
  • Remove the old transmission filter and install a new filter, ensuring a proper seal.
  • Reinstall the transmission pan with a new gasket, torquing bolts to manufacturer specifications (typically around 8-10 ft-lbs).

5. Reconnect Battery and Clear Codes

• Reconnect the negative battery terminal.
• Use the OBD-II scanner to clear the P0700 code and any additional transmission codes.
