Automatic Transaxle Fluid It is not necessary to check the transaxle fluid level. A transaxle fluid leak is the only reason for fluid loss. If a leak occurs, take the vehicle to the dealership service department and have it repaired as soon as possible. You may also have your fluid level checked by your dealer or service center when you have your oil changed. Notice: We recommend you use only fluid labeled DEXRON@-Ill,because fluid with that label is made especially for your automatic transaxle. Damage caused by fluid other than DEXRON@-Ill is not covered by your new vehicle warranty. Manual Transaxle Fluid It is not necessary to check the transaxle fluid level.
