Neglecting to change the transmission fluid at the recommended intervals can result in a variety of issues, such as:


  • Increased transmission slippage or delayed gear engagement

  • Premature wear and tear on the transmission components

  • Reduced fuel efficiency

  • Potential transmission failure or the need for costly repairs
