1.Warm the engine: Start your car and run it for a few minutes to warm up the engine and its components, including the transmission. This helps to ensure the fluid level is accurately representative of its normal operating state.
2.Locate the transmission dipstick: In Mercedes E 320s, the transmission fluid dipstick is usually found in the engine bay. It may be labeled with a yellow or orange cap marked "ATF" (Automatic Transmission Fluid) or a dipstick with a red handle.
3.Pull out the dipstick: Hold the dipstick by its handle and remove it slowly. Be careful not to spill any fluid while doing so. Wipe off the dipstick with a clean cloth or rag to ensure a clear reading.
4.Check the fluid level: Carefully examine the dipstick to see where the fluid level is in relation to the two mark indicators on the dipstick. The levels are usually marked with an upper level (usually near the top) and lower level (usually near the middle) line.
5.Evaluate the color and condition: In addition to the fluid level, also pay attention to the color and condition of the transmission fluid. It should be a translucent red color when new, and should not be discolored or black, as those are signs of fluid deterioration. Burnt or dirty transmission fluid may require a change.
6.Add fluid if needed: If the fluid level is too low, you can add recommended automatic transmission fluid to bring it back to the proper level. Add the fluid slowly, checking the level as you go. Do not overfill the transmission fluid as that can cause damage.
7.Reinsert the dipstick: Once you've added fluid (or if no addition was necessary), reinsert the dipstick firmly all the way back into its tube. This helps ensure an accurate reading for the next time you need to check the transmission fluid level.
