In this article, LMR explains how to change the fluid in your manual transmission on the S197 Mustang chassis. The transmission fluid in your Mustang is a vital maintenance part that needs to be changed from time to time. Keeping your transmission fluid clean and cool is vital to prolonging your transmission life expectancy. Routine transmission maintenance should include fluid change every 30,000 miles to keep your shifts smooth and your performance up to par.

Today in the shop, we will be working on employee Jay Walling's 2012 GT500. This car is nearing 200,000 miles, so keeping the transmission fluid fresh is one of the top priorities. These same general steps can be used on all 2005-2014 Mustangs with manual transmissions. Depending on the year and make of Mustang you are working on, the fill and drain locations and fluid capacities can vary. Check out our Mustang Fluid Capacity Articles to learn more!

Tools Needed

  • Lift or a jack and a set of jack stands
  • 3/8" drive ratchet
  • Drain pan
  • Funnel
  • Few feet of 3/8" hose
