WOW to Add Fluid Refer to the Maintenance Schedule to determine what kind of transmission fluid to use. See "Recommended Fluids and Lubricants'' in theIndex. If the fluid level is low, add only enough of the proper fluid to bring the level up to the COLD area for a cold check or the HOT area for a hot check. It doesn't take much fluid, generally less than a pint. Don't overfill.We recommend you use only fluid labeled DEXRON@-I11 or DEXRON@-IIE, because fluids with that label are made especially for your automatic transmission. Damage caused by fluid other than DEXRON@-I11 or DEXRON@-IIE 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. Manual Transmission Fluid When to Check A good time to have it checked is when the engine oil is changed. However, the fluid in your manual transmission doesn't require changing. How to Check Because this operation can be a little difficult, you may choose to have this done at a GM dealership Service Department. If you do it yourself, be sure to follow all the instructions here, or you could get a false reading. NOTICE: Too much or too little fluid can damage your transmission. Too much can mean that some of the fluid could come out and fall on hot engine parts or exhaust system, starting a fire. Be sure to get fluid. an accurate reading you if check your transmission Check the fluid level only when your engine is off, the vehicle is parked on a level place and the transmission is cool enough for you to rest your fingers on the transmission case. 6-31
