While a direct Type F replacement doesn't exist, many mechanics recommend using Mercon or Dexron III/III-H fluids. However, it's strongly advised to consult a Mustang specialist or a reputable mechanic familiar with classic car transmissions before making any fluid changes. They can help determine the best fluid for your specific transmission and potentially identify any underlying issues that might be exacerbated by using an inappropriate fluid. Improper fluid can lead to significant transmission damage.
