You check the transmission fluid level by locating and using the transmission fluid dipstick, which is usually found near where the transmission or transaxle meets the rear of the engine. It often has a yellow or orange handle and looks similar to the engine oil dipstick
. Steps to check transmission fluid:
- Warm up the engine by running it for about 10 minutes, as transmission fluid should be checked at operating temperature for accuracy. The vehicle should be on a level surface, with the engine running, and the transmission in Park or Neutral
- Open the hood and find the transmission fluid dipstick.
- Remove the dipstick and wipe it clean with a cloth or towel
- Reinsert the dipstick fully, then remove it again to read the fluid level. The fluid should be within the marked safe range on the dipstick, often indicated by two lines or dots. If the fluid is below the minimum mark, it needs topping up
- The fluid should be a clear red color (for automatic transmissions). If it is dark, brown, or smells burnt, the fluid likely needs to be changed
- If topping up is needed, use a funnel to add the correct type of transmission fluid through the dipstick tube, adding slowly and rechecking the level to avoid overfilling
Note that some modern vehicles do not have a transmission dipstick because they use sealed transmission systems; in those cases, checking fluid levels requires specialized tools or professional service
. In summary, check transmission fluid at the dipstick tube near the engine- transmission junction, with the engine warm and running, on a level surface, and the transmission in Park or Neutral
