For an Automatic Transmission:
1. Locate the transmission dipstick: It's usually a long dipstick with markings for "ADD" and "FULL". It's often located near the engine, but it's position varies by model year. Consult your owner's manual for its exact location.
2. Warm up the transmission: Run the engine for a few minutes to allow the transmission fluid to reach its operating temperature. This is crucial for an accurate reading.
3. Check the fluid level: Remove the dipstick, wipe it clean with a lint-free cloth, reinsert it fully, and remove it again to check the level.
4. Add fluid (if needed): If the fluid level is low, add the correct type of automatic transmission fluid specified in your owner's manual. Do not overfill! Adding too much fluid can damage the transmission. Add a small amount at a time, checking the level frequently.
5. Check again: After adding fluid, wait a few minutes and recheck the level to ensure it's within the "FULL" range.
6. Proper disposal: Used transmission fluid is hazardous waste. Dispose of it properly according to local regulations.
For a Manual Transmission:
Manual transmissions generally don't have a dipstick. They typically require a fluid change rather than just topping off. This involves removing the drain plug from the transmission case, letting the fluid drain completely, replacing the drain plug, and then adding the correct amount of gear oil through the designated fill hole (often located on the side of the transmission case). The amount of fluid and the correct type of gear oil are specified in your owner's manual. This is a more involved process and often requires mechanical expertise.
Important Considerations:
* Type of fluid: Using the wrong type of transmission fluid can severely damage your transmission. Always refer to your owner's manual to identify the correct type.
* Safety: Work on a level surface, and never work under a vehicle without properly supporting it on jack stands.
* Professional help: If you are unsure about any part of this process, take your car to a qualified mechanic. Improper fluid levels or the use of incorrect fluid can cause significant damage to your transmission.
Remember to consult your owner's manual for specific instructions and recommendations for your 1990 Chrysler LeBaron. It will provide crucial details about the type of transmission you have, the correct fluid type, and the location of the dipstick or fill plug.
