Its probably a good idea to change all of your fluids if you have just acquired the vehicle that way you know the starting point. Changing the automatic transmission fluid depends on how you drive it and what climate you drive it in. Make sure you check the condition of the two rubber hoses going to the transmission cooler from the transmission, if they look old replace them. A local hydraulic shop can replace the hose and reuse the existing fittings. In hot climate on a daily driver should probably be changed every year. If you drive only weekends like me, maybe every couple years. The transmission is the one toward the front of the car and the "Differential" is the one toward the rear of the car. The transmission can be filled from the dipstick tube in the engine compartment. Don't over fill. Also, last I heard was that there were no transmission filter screens available. James?? Use regular 80-90 weight gearoil in the Differential.
