What is automatic trans-axle fluid?
Automatic Transmission Fluid. When you change your transmission fluid, always use the recommended (listed in the manual) fluid. (1989-91 owners, ignore the manual and use ATF+3). Don't just assume your mechanic or dealer knows what fluid to use. Ask them what they will use and make sure it's the right one. (Some people recommend watching the mechanic pour it in, and for good reason! We have been told about mechanics who said they were using ATF+3 when they were not. Is your transmission worth the $10 you save on a cheaper fluid?) All Chrysler four-speed automatic transmissions* are very sensitive to the quality of the transmission fluid. Only use the ATF+[3 or 4] in these transmissions. Do not use Dexron or Mercon.
What is the procedure to check the automatic transaxle oil level in Pontiac sunfire 97 that model as no dip stick?
Checking the fluid level is done from underneath the vehicle. There is a plug located in the side of the transaxle housing unscrew the setscrew and put your ginger in, if you can feel the fluid right at the level or a little comes out then it is at the right level, much below this then add some fluid.
