General Safety Precautions:
* Work in a well-ventilated area. Transmission fluid fumes are harmful.
* Wear gloves. Transmission fluid can irritate skin.
* Let the engine cool completely before checking or adding fluid. Hot fluid can cause burns.
* Have the correct type of transmission fluid on hand. The owner's manual will specify this.
Automatic Transmission:
1. Locate the transmission dipstick. It's usually located on the transmission itself, often with a bright colored handle. It might be near the engine, but will be distinct from the engine oil dipstick.
2. Check the fluid level. Remove the dipstick, wipe it clean with a rag, reinsert it fully, and remove it again. The fluid level should be within the "ADD" and "FULL" marks on the dipstick. Some dipsticks only have a "FULL" mark.
3. Add fluid if necessary. If the level is low, slowly add the correct type of transmission fluid using a funnel. Check the level frequently to avoid overfilling. Overfilling can be just as damaging as underfilling.
4. Run the engine briefly. After adding fluid, run the engine for a minute or two to circulate the fluid, then recheck the level. You may need to add more fluid.
5. Check for leaks. After adding fluid, inspect the transmission pan and surrounding area for any leaks.
Manual Transmission:
Manual transmissions generally don't have a dipstick. They are typically filled to a specific level through a fill plug. This is more complicated and should only be attempted if you have experience working on vehicles. Incorrect filling can easily damage the transmission. It's highly recommended to consult a mechanic if you need to add fluid to a manual transmission. The procedure often involves removing the fill plug to check the fluid level with a tool.
Important Considerations:
* Low fluid level is a symptom, not the problem itself. A low fluid level usually indicates a leak, a malfunctioning transmission, or a seal failure. Simply adding fluid won't fix the underlying issue. If you are frequently adding transmission fluid, you need to find and fix the leak.
* If you're unsure about anything, consult a mechanic. Improper fluid addition can cause significant damage to your transmission. It's better to be safe than sorry.
* Refer to your owner's manual. This is the most important source of information for your specific vehicle.
