The transmission fluid in your Mini Cooper is essential for the transmission to function as it should. It keeps gears sliding smoothly, prevents overheating and helps prolong the life of moving parts. While some vehicles are designed so that changing fluid is a simple procedure that can be done at home, other vehicles require special tools or knowledge or have special requirements.

The transmission fluid in your Mini Cooper is essential for the transmission to function as it should.

The transmission fluid in your Mini Cooper is essential for the transmission to function as it should. Transmission fluid lubricates the gears and bearings, protects against corrosion and acts as a hydraulic fluid to push the gears in the transmission. The transmission case houses an internal oil pump that pressurizes this fluid, which then circulates throughout every moving part of your Mini Cooper’s automatic transmission.

The amount of time you spend driving determines when you should change your Mini Cooper’s transmission fluid. A good rule of thumb is every 30,000 miles or less than three years (whichever comes first). If you’re unsure when it’s time to get new fluids for your vehicle, contact us today!

How long does it take to change transmission fluid?

The amount of time it takes to change your transmission fluid depends on the type and quantity of fluid you’re draining. For example, if you’re using a transmission flush that contains more than one liter of fluid and there’s no drain plug in your car, it could take as long as two hours.

If you’re changing your own transmission fluid with a funnel and some towels, on the other hand, the job should only take about 20 minutes—or even less if you have an automatic transmission.

Why do you need to change transmission fluid?

You need to change your transmission fluid because it lubricates and cools the gears, cleans them, removes metal particles from the gears, prevents corrosion in the transmission and keeps the transmission running smoothly.

Can you wait longer than the recommended interval to change your transmission fluid?

The answer to this question should be a clear “no.” If you wait too long, your transmission could become damaged. You could also experience a number of other problems, including transmission failure. If you wait too long, you could end up having to pay for expensive repairs.

How often do you need to flush your transmission fluid?

Flush the transmission fluid every 30,000 miles. You can do this at home by following these steps:

  • Buy an automotive transmission flush kit from an auto parts store. These kits include a gallon of fluid and a set of manual instructions that tell you how to complete the job safely and effectively.
  • Remove your Mini Cooper’s drain plug from the differential cover, the metal piece where you fill up with oil on older cars, and remove it from your vehicle, along with any other plugs or caps that may be in your way (if there are no other plugs or caps installed on your Mini Cooper). Be sure not to lose any gaskets or seals when removing them!

Many car owners don’t realize that their car’s transmission needs regular care and maintenance.

It’s easy to forget about the transmission on your car. After all, it doesn’t get as much attention as the engine or even the brakes. But a good transmission is essential to keeping your vehicle running well and safely. That’s because it makes sure your gears are in the right place at all times, and if they’re out of whack, you can run into problems like shuddering during acceleration or harsh shifting while driving.

The fluid inside of your car’s transmission keeps things running smoothly by lubricating both mechanical components and seals within this complex part of the powertrain system. It also acts as an important heat transfer medium for cooling purposes; without proper protection from heat generated by friction within this device, it could wear out prematurely or experience internal overheating which could lead to serious damage (such as breakage). While there are many types available on today’s market with varying characteristics depending on their intended function (from low friction formulations designed specifically for use in racing applications where cornering speeds exceed 100 mph); most will contain additives that help prevent corrosion while simultaneously reducing friction levels between moving parts within either manual transaxles.

More so, changing the transmission fluid in your Mini Cooper is fairly simple, but it’s a messy job that requires some special tools. You’ll need to make sure you have adequate workspace, clear away any debris or dirt from underneath your car and above the transmission cover before working on it, and collect any old transmission oil for disposal.

Checking the Oil Level

Checking the oil level in your Mini Cooper is a very simple process that you can do yourself. The first step is to locate your car’s oil dipstick, which will be either located under one of two places:

  • On the engine block near where your engine meets the transmission (if you have an automatic transmission)
  • Underneath one of your front seats (if you have a manual transmission)

Empty the transmission oil. Be sure to collect it in a suitable container to dispose of later.

  • You should not need to remove the transmission pan.
  • Be sure to collect the old fluid in a suitable container so you can dispose of it safely later on. Read Also: Tips on What Transmission do in a Car

Clean around and inside the fill plug for the transmission.

  • Clean around and inside the fill plug for the transmission.
  • Use a rag, paper towel or other suitable material to clean around and inside the fill plug. Do not use your hands directly on the plug itself.

Remove the fill plug with an appropriate socket wrench.

Make sure you use a socket that fits the plug well, and is long enough to reach the fill hole

Insert your finger into the hole where the plug was located. If you can feel oil, then your Mini is full enough.

If you’re still unsure if your Mini’s transmission fluid is full enough, insert your finger into the hole where the plug was located and feel around. If you can feel oil, then your Mini is full enough. If there’s no oil at all, then you need to add more fluid.

Use a 3/8-inch drive ratchet to loosen and remove drain plug from underneath Mini Cooper S, if necessary. Be sure to collect transmission oil in a suitable container to dispose of later. Read Also: How Much Does it Cost to Repair Transmission

Check that all plugs are tightened firmly before adding new fluid or operating your car.

  • Check the oil filler cap, dipstick and oil level sensor for any signs of damage or leakage.
  • If your car has been serviced recently, check that all plugs are tightened firmly before adding new fluid or operating your car.

You can check your transmission fluid level on your own but be sure you have a safe place to collect old fluid and dispose of it properly

The easiest way to do this is with a transmission dipstick, which should be stored in the driver’s side door pocket or glove box. To use the dipstick, pull out the old one and replace it with an empty one (in case any excess fluid spills). Then remove the cap from your MINI Cooper’s oil filler hole and push the end of the dipstick into it until you feel resistance. Pull out the dipstick and look at its markings; if they indicate that there’s not enough fluid in there, add some new transmission fluid using either a bottle or syringe (if using more than 500 millilitres). If they indicate that there’s too much fluid in there, or if they’re right on target, you can skip step 3!


As you can see, there are many factors to consider when it comes to changing your Mini Cooper’s transmission fluid. It’s important that your car gets regular maintenance so that it will last longer and run smoothly. We hope this article has helped you understand what goes into changing transmission fluid in your Mini Cooper as well as how often it should be done. Transmission fluid is a very important part of your vehicle and should be checked regularly. If you are unsure about checking your own transmission fluid, then it is best to contact a professional mechanic at a local auto repair shop. They will be able to help you with any questions or concerns that you might have about your Mini Cooper’s transmission system.
