Install the dipstick by pushing it back in all the way; wait three seconds, and then pull it back out again. 4. Check both sides of the dipstick and read the lower level. Repeat the check procedure to verify the reading. (160°F and 200°F), add or drain fluid as necessary to bring the level into the HOT band. If the fluid level is low, add only enough fluid to bring the level into the HOT band. It does not take much fluid, generally less than 0.5 L (1 pint). Do not overfill. 6. If the fluid level is in the acceptable range, push the dipstick back in all the way, then flip the handle down to lock the dipstick in place. 10-15 Manual Transmission Fluid It is not necessary to check the manual transmission fluid level. A transmission fluid leak is the only reason for fluid loss. If a leak occurs, take the vehicle to your dealer service department and have it repaired as soon as possible. See Recommended Fluids and Lubricants on page 11‑12 for the proper fluid to use. Consistency of Readings Always check the fluid level at least twice using the procedure described previously. Consistency (repeatable readings) is important to maintaining proper fluid level. If readings are still inconsistent, contact the dealer. Hydraulic Clutch It is not necessary to regularly check brake/clutch fluid unless you suspect there is a leak in the system. Adding fluid will not correct a leak. A fluid loss in this system could indicate a problem. Have the system inspected and repaired. 5. Safe operating level is within the HOT cross hatch band on the dipstick. If the fluid level is not within the HOT band, and the transmission temperature is between 71°C and 93°C
