2003 Infiniti I35 Questions & Answers

  • What happens if I "ride" my Infiniti's brakes? Riding the brakes or keeping your foot on the brake pedal (even lightly) can lead to transmission issues. Pay attention to how often you apply your brake and use engine braking when possible.
  • How much can my Infiniti tow?   Think twice before volunteering to tow your friend's moving trailer, no matter how light the load might seem. The added weight can cause issues with your transmission if your vehicle isn't equipped to handle the load. Double check your owner's manual to ensure your I35 is equipped with a towing setup and can handle whatever you're thinking about towing.
  • When should I have my I35's transmission fluid checked or exchanged? Maintaining your Infiniti I35 transmission fluid is one of the best ways to maintain your transmission's health. A general rule of thumb is to have your transmission fluid checked and changed about every 30,000 to 60,000 miles, but that timeline can change if you're hard on your Infiniti. The good news is that transmission fluid leaks are affordable to repair and easy to spot.
  • Can Infiniti I35 transmission fluid leak? Yes. Infiniti I35 transmission fluid can leak as time passes, which may lead to transmission problems. Transmission fluid leaks are often caused by worn or damaged transmission components, such as the transmission pan, cooler lines, seals, or housing. An overfilled transmission may also be behind your transmission fluid leak.
