How to Check Transmission Fluid


One of the most important parts of owning a car is making sure your vehicle is getting all the routine maintenance it needs. This is so it continues to give you great performance around Littleton, Parker, and Castle Rock, CO.

A part of this maintenance includes inspections. While most inspections should be performed by a professional—like the ones here at McDonald Hyundai—there are a few checks you can do yourself at home. This includes checking the transmission fluid, which we explain how to do in this guide.

Step-by-Step Guide to Check Transmission Fluid

To check and see if it is time to change your transmission fluid, just follow these easy steps:

Step 1: Start the Engine

You will first need to get the engine warmed up before you go ahead and check the transmission fluid. Have your car parked on an even surface and the gearshift in Park and let your engine run for a little bit.

Step 2: Locate the Dipstick

Next, you can pop open the hood and find the automatic transmission fluid dipstick.  Once you have found it, pull out the dipstick and wipe it clean before replacing it slowly back in.

Step 3: Check Fluid Level

Once you have placed the dipstick fully back in, you can then pull it out once again. At this point, you are now ready to get a reading on its level. There should be marks on the dipstick, with one reading full. If fluid levels are below that marking, you are going to need to add more fluid.

Step 4: Check Fluid Condition

Before doing that, though, you will also want to inspect the condition of the transmission fluid. If the fluid is a red or pink color, then your fluid is still healthy and in great shape. If you notice it is a darker, more brownish red or even black color, then you will want to go ahead and schedule a transmission fluid replacement.

Step 5: Fill or Replace Transmission Fluid

If the fluid is still in good condition, then you can go ahead and just add more fluid until it reaches the fill line on the dipstick. Use a funnel to make it easier to pour in the fluid and do this incrementally, so you don’t overfill.

Even after filling your transmission fluid, make sure to regularly check it again in the next few days to make sure it wasn’t a leak that caused the low levels in the first place. If it does become low again, you will want to have your car serviced to fix the leak. Also, if the fluid color is dark, you will want to have your transmission fluid flushed out and replaced with fresh, new fluid.
