How to Check & Add Automatic Transmission Fluid – Step-by-Step

Checking your vehicle’s transmission fluid is a preventative maintenance procedure that should be done at least once a month in order to spot potential early warning signs such as a low fluid level or worn out dirty/burnt fluid. Here’s how:

  • 1) Locate the Dipstick
  • 2) Run the Vehicle
  • 3) Pull Dipstick Out
  • 4) Check the Fluid for Color, Smell & Consistency
  • 5) Reinsert Dipstick and Pull it Out Again

  • Summary
  • If you cover a lot of miles, haul heavy loads or drive in stop and go traffic, you should check more often – say every 2 weeks. This will give you time to top up or change the fluid before these issues cause serious transmission problems that can damage or destroy your transmission.

    If your vehicle is showing signs of transmission problems such as slipping, hesitating or grinding, the first thing you should do before calling a transmission shop for repairs or replacement is check your fluid level. Topping up or changing fluid might be all that is needed to solve the issue and is obviously a lot cheaper than having repair work done!

    To check your fluid, follow these steps:

    What You’ll Need

    • Clean, lint free rag
    • Appropriate transmission fluid for your vehicle
    • A funnel

    1) Locate the Dipstick

    To check your vehicle’s automatic transmission fluid, pop the hood and find the dipstick handle sticking out of your transmission.

    Front Wheel Drive
    It is typically found sticking out of the transaxle near the front (see below).

    Rear Wheel Drive
    The dipstick can probably be found near the back of the engine area as shown below:

    transmission-fluid-dipstick-location-rear-wheel-drive

    NOTE: To check the fluid in a manual transmission, the vehicle typically needs to be raised on a hoist or blocks in order to access the plug on the bottom of the transmission.

    2) Run the Vehicle

    Park your vehicle on a level surface and leave the engine running. Leave it in Park or Neutral gear with the parking brake on. If your vehicle has been sitting for a while, give it time to warm up to normal operating temperature (engine should feel warm). Note that some Hondas for example must be checked within 60-90 seconds of the engine being shut off.

    3) Pull Dipstick Out

    Locate and remove the transmission fluid dipstick. If for some reason you can’t find it, refer to the images above or your owner’s manual.

    4) Check the Fluid for Color, Smell & Consistency

    Dip your finger into the fluid on the dipstick and rub it between your fingers. You want to see an almost clear, bright red or pinkish color (see colors below) with a thick, oily consistency.

    transmission-fluid-colors

    If it is very dark red/reddish brown, has a noticeable burnt smell, appears very thin/watery and/or you can see small metallic particles in it, then the fluid (along with the transmission filter) needs to be changed to avoid damage.

    If you find large metallic particles, a strong burnt smell and/or black fluid, then internal damage may have already occurred. Seek the assistance of a mechanic immediately.

    5) Reinsert and Check the Fluid Level

    If the fluid is red, clear and free of particles, the next step is to check the fluid level. Clean the dipstick with a fresh, lint free rag, reinsert it and pull it out again. If the fluid is low, use a funnel to pour some fluid down the dipstick tube to reach the line. Don’t overfill, because that can actually cause damage too!

    6) Replace Dipstick and Close the Hood

    You’re done! Good job.

    TIP: In addition to checking the level and quality of fluid using the dipstick, be sure to look under your car occasionally for stains on the driveway or transmission pan to make sure that your fluid isn’t leaking.

    What if the Fluid is Really Low?

    If your fluid is low, not only could it cause significant damage, but it can point to a more serious problem.

    The lack of fluid could be caused by a leak, which you might see under the car, but sometimes, a leak may only occur while you’re driving.

    Either way, keep a close eye on the fluid level, and consult a mechanic if the condition continues.

    What if My Car Doesn’t Have a Dipstick?

    Believe it or not, many new vehicles don’t have a transmission dipstick, and it takes a trained technician with specialized tools to check the fluid level. If you can’t locate a dipstick under the hood, consult your owner’s manual.

    Consult your owner’s manual for the exact procedure and type of fluid to use.

    2007 Monte Carlo 3.5 Some times when taking off from stop light trans fails to respond but then it will slam and take off. Check trans fluid every time when this happens, but is full.Shifts fine after taking off.

    I’ve got a 98 ram 2500 automatic gas. The transmission was just slipping whenever i punch the gas or take off fast. But now it won’t go into park or engage in any gear. If i give it gas it’ll eventually catch but won’t shift out of 2nd. But when i stop i got to start the process over again. And if i undo the hose ran to the radiator it pours out atf . Any suggestions?

    My Cadillac 07 CTS 2.8L wont go into gear once it warms up. They say low on transmission fluid ,but every time I jack up the car I add. They say when the fluid starts to run out its full. How do I know if its full?

    I’d been driving my Buick regal, for a long time with low fluid. I changed it several times but evidently never put in enough fluid. The dipstick was a shiny metal which made it damn near impossible to get a true reading. Today while preparing for a long drive I decided to remedy the shiny stick problem. I used acetone to degrease the end of the dipstick, then used some “cold blue” (birchwood casey) on a q tip to BLUE the end of the stick. That’s when I found out I’m 2.5 qts low.Now it’s easy to see the level. I topped up and now my car feels like New. You’d think the manufacturers would have figured out that a shiny dipstick ain’t the right color.
