No. It is only a fluid change. Use the correct fluid, 3306 or Type T-IV, and add same quantity you drain out which should be 4 quarts.
Mobil calls their fluid 3306. It is identical to the fluid that Toyota and Aisin (the manufacturer of the automatic transmission, call Type T-IV. All other fluid blenders and/or marketers will reference at least one of these names on bottles containing their own brand of compatible ATF. There is NO UNIVERSAL ATF, regardless of what a marketing person claims.
