See "Recommended Fluids and Lubricants" in the Index. Add fluid only after checking the transmission fluid HOT. (A COLD check is used only as a reference.) If the fluid level is low, add only enough of the proper fluid to bring the level up the HOT area for ahot to check. It doesn't take much fluid, generally than a less pint. Don 't overfill. We recommend you use only fluid labeled DEXR0N'-111, because fluid with that label is made especially for your automatic transmission. Damage caused by fluid other than DEXRON@-I11 is not covered by your new vehicle warranty. After adding fluid, recheck the fluid level as described under "How to Check." When the correct fluid level is obtained, push the dipstick back in all the way; then flip the handle down to lock the dipstick in place. 3. Check both sides of the dipstick, and read the lower level. The fluid level must be in the COLD area for a cold check or in the HOT area or cross-hatched area for a hot check. 4. If the fluid level is in the acceptable range, push the dipstick back in allthe way; then flip the handle down to lock the dipstick in place.
