Q: How to change the transaxle fluid and Automatic Transmission Filter?
A: To change the transaxle fluid, first ensure that the vehicle has cooled down completely. Purchase the recommended transaxle fluid and a new filter. Raise the vehicle on jackstands and remove the front and side transaxle pan mounting bolts. Loosen the rear pan bolts and carefully pry the transaxle pan loose to drain the fluid. Remove the remaining bolts, pan, and gasket, and clean the gasket surface of the transaxle. Drain the fluid from the pan, clean the pan, and remove the filter and seal. Install a new filter seal and filter. Clean the gasket surface on the transaxle pan and install the new gasket. Tighten the bolts gradually and lower the vehicle. Add the specified amount of fluid and check the fluid level. If necessary, add fluid until it reaches the bottom of the check hole. Check the condition of the fluid and compare it to new fluid. Install the check plug securely. For 2004 and earlier ION models, follow specific instructions for the AF23-5 transaxle or VT25-E transaxle. Finally, check for leaks and dispose of the old fluid properly.
