What Should I Do if My Transmission is Slipping?

Your car’s transmission is one of its most complex systems. There’s a lot that needs to happen in order for it to function and shift gears properly. While regular maintenance is always a good idea, it could also be the beginning of a more serious problem, especially if it isn’t given attention immediately. You should definitely know the early warning signs that your transmission needs to be serviced. 

The Signs That Your Transmission is Slipping

There are many possible indicators that your transmission might be having trouble, the most notable is a slow or delayed shift when accelerating. You can usually tell that your car is shifting gears by the change in pitch and a drop in your RPM. If your car is changing gears suddenly without acceleration or deceleration from you, get your car serviced immediately as it could be dangerous to drive. Other warning signs include grinding noises, revving or “chugging” sounds, issues with driving in reverse, or If you smell burning or other unexpected smells. Don’t wait until you see all of these signs, the sooner you get help, the better chances you have. 

The Causes Behind Your Transmission Issues

Because automatic transmissions especially are such complex machines, there’s a quite a few possible reasons for your troubles that range from more common to more serious.

Lack of Fresh Transmission Fluid Can Cause Slipping

The majority of transmission issues stem from low or burnt out transmission fluid. Luckily this is the easiest and least expensive way to regularly maintain your transmission. Depending on the manufacturer, you will want to change the fluid every so often. A well taken care of transmission is bound to last you many more years than one that hasn’t been given enough attention. Take your car to your mechanic to get a fluid flush if the transmission fluid is low, burned out, or old.

Worn Out Transmission Gears Can Begin to Slip

Failure to regularly maintain your transmission fluid can begin to wear on your gears. The excess heat that is usually dispersed by fresh fluid builds up and causes the gears on your transmission to slip. If they cannot engage properly they will slip out of synch. There could also be a malfunctioning set of gears, which could be caused by an error in the car’s production.

Your Transmission Has A Defective Solenoid

The solenoid is the part of your transmission that controls the flow of transmission fluid using electromagnetic fields. When you shift gears, the solenoid pushes transmission fluid into the valve body to engage the next gear. A defective solenoid could be causing a lack of transmission fluid to enter the transmission, which could cause overheating and slipping. If you’ve been regularly servicing your transmission fluid, replacing the solenoid could be the next step to solving your issues.

Worn Out Transmission Bands Can Cause Slipping

Bands are the elements of the transmission that link the gears of an automatic transmission together. In order for the transmission to reach optimal performance, bands and clutches must engage and release the different gears with precision. Broken or worn out transmission bands can cause slipping and need to be either adjusted or completely replaced. Clutch plates in both the transmission and torque converter might also be worn out and require a replacement. These issues most commonly stem from a lack of clean transmission fluid.

Your Clutch Needs to Be Replaced

Rather than a main clutch in a standard or manual transmission, automatic transmissions employ the use of a torque converter. These converters connect to the engine through the bell housing. Both torque converters and manual clutches rely heavily on clean transmission delivery from the solenoid. Over time, clutches are worn out from normal use and commonly need to be replaced at some point after the midpoint of the car’s life.

Spring Car Care Tips

With rising temperatures on their way, the strategy for car care changes drastically! During the winter months, many people don’t pay as much attention to keeping their cars in shape, especially in Massachusetts. The large amounts of snow end up covering cars, and cleaning them off is usually the most pressing thing to worry about. After the snow is done and the sun is setting later, take the time to pay attention to your car to have it running its best all spring long.

Tire Pressure

As temperatures get colder during the winter, tire pressures decrease, which probably caused you to fill up your tires during the colder months. As temperatures increase into the spring, so does tire pressure. If it rises past the manufacturer’s standards, it can ruin your car’s ability to drive and the fuel economy. Make sure to get your tires checked once it gets warmer out. Check for dry rot, tread depth, or any low pressures due to minor leaks. 

Alignment and Suspension

Snowy and frozen roads take a toll on your car. Driving on roads with potholes and rocks can ruin the alignment of your car and damage suspension components. Take your vehicle to get the alignment and suspension checked if you had a long winter of commuting around on frozen ground. Listen for any noises over bumps or when going over driveways as that is a tell-tale sign something is wrong. 

Wiper Blades

Check your wipers for signs of damage. If you had a lot of snow piling on your car and freezing, the blades might have some cracks or don’t wipe your windshield correctly anymore. Many car owners tend to change out their wiper blades after the winter is over anyways. 

Wax and Wash Your Car

Driving in winter weather can make your car the dirtiest it can get. Driving higher speeds on highways will throw road salt and dirt at your vehicle. Be sure to give your vehicle a thorough car wash, making it a point to clean the undercarriage. That’s where rust can form from snow and ice. 

Clean Inside Your Car, Too

Spring is a great time to clean the inside of your car. No one wants to be outside in the winter cleaning out their car. While you are spring cleaning your home, add your car into the mix! Snow and salt will settle into your floormats, making the interior dirty. Vacuum and wipe down the steering wheel and dashboard to give your car a fresh look.

Check Under the Hood

Open up the hood of your car to check the engine and make sure everything looks right after a long, cold winter. Check hoses and belts to make sure the cold didn’t wear them down. This is something that should be professionally inspected, especially if you are not too experienced with cars.

5 Common BMW Issues You May Run Into

Owning a BMW or any other type of luxury car is a wonderful experience. You get to cruise your favorite roads while basking the presence of amazing craftsmanship and luxury automakers. However, just like with any normal car, a BMW overtime will need repairs and maintenance done to make sure it is operating at optimal levels. With all types of repairs, it is better to have a vast knowledge of what issues your car may run into so you can handle them as quickly as possible. Repairs left undone could turn into bigger and more costly problems down the line. For BMW cars, there are a few brand-specific problems that have come up in the past that have become “common” to BMW owners. Below is a list of the most common issues you should expect to run into so you can plan accordingly.

5 Common BMW Problems You May Run Into


Steering Wheel Vibrates When Braking

BMW cars are great for moving quickly, being agile, and looking sporty but have had issues in the past when the brakes are applied. Although mostly seen with the 3 series, the steering wheel of the BMW will constantly vibrate when braking. This problem could get worse if not looked at and the vibrations could get worse down the road. This is when you should take it into a BMW specialist to possibly repair the wrap rotors of your BMW.

Oil Leaks

If you are a frequent driver that racks up a lot of miles over time, then you should be wary of oil leaks. BMW users have frequently complained of oil leaks when dealing with a BMW vehicle that hs over 55,000 miles on it. The most common issue that causes this leak to happen is valve cover gaskets and oil pan gasket malfunctions. If this happens make sure you bring your vehicle to a shop to check out the oil and other fuel systems.

Power Steering Leak

If you ever see leaked fluid and/or hear screeching noises while steering then your power steering fluid is most likely leaking. A leak in the power steering oil reservoir usually comes from a faulty hose. This is a serious issue that needs to be checked immediately as it affects the safety of your vehicle as well as the functioning of your car while driving.


Sputtering usually happens when you are accelerating or moving at a high speed in your BMW. This issue is caused by a high-pressure pump malfunction. When the pump is malfunctioning the stream of fuel being pumped into the engine is inconsistent and may lead to a failure to turn over if it is not looked at right away.

Electronic Problems

The most common issue with common European cars is that there tend to be electronic problems over time and this has happened over multiple series of BMW vehicles. With improper wiring systems, there could be a development of constant faults with some electronics of the car such as the AC not coming on, the wipers not working, etc. Regardless of what you are dealing with, the team at Boston Motor Werks has the skills and experienced necessary to tackle any electrical or programming issue your BMW may run into.

mechanic holding a car air filter over an engine

We spend a lot of our time in our car, more than 293 hours a year according to a survey from the AAA Foundation for Traffic Safety, so it’s important that we make it as comfortable as possible, wouldn’t you agree? Clean air is essential for not only our comfort but also for our health- therefore it is crucial to consider getting your car’s air filter changed this spring.
The air filter in your car should be changed about every 20,000 miles or so, this can be translated to spring car maintenance must. Take a look at these 3 reasons you should have an air filter change this spring:

Your BMW Will Thank You

Well, not all of us have a Mercedes or Porsche but that doesn’t mean we shouldn’t baby our vehicles. A clean car is a happy car-plus you might be happy with the dust-free environment as well.
Think of the inside of your car like a fish tank when you don’t change the filter the water gets grimy as dirt start to build up inside. It’s about the same concept as your vehicle, as you should be trying to keep the dust from settling on the dash, seats, and compartments.

Keep Out the Pollen!

If your vents are not working properly, you may end up with debris from outside coming through your vents, including pollen. If you are like many people in the spring, pollen can be a major issue-so deciding on air filter services is a very good idea.

Think of your car as a sanctuary spot from the pollen outside-you won’t be able to always avoid it, but you can certainly make it much easier on yourself by keeping up with a working air filter.

It’s Just Good Maintenance

Routine vehicle maintenance is crucial for the longevity and smooth operation of your car. Though air-filters have improved over time, they still need to be serviced to keep problems from arising in your engine. Changing your air filter will prevent spoiled spark plugs that can affect performance or have negative effects on the engine.
All things considered, this is a quick and cheap service that will be worth spending a little time and money on. If you have additional question or concerns, don’t hesitate to call Boston Motor Werks, we’ll be happy to get you taken care of!

When Should I Have My BMW Serviced?

When determining time lines to have your BMW services and inspected, you should most often refer to your owner’s manual; this manual will usually indicate the mileage benchmarks where you should have your BMW inspected.

BMW are such high tech cars that the vehicle itself will tell you when you need to have your car serviced; older models have lights that will let you know when you need to bring your car into our shop. The lights are green, but when they turn red, it’s time to bring your vehicle into our garage. We recommend having an oil change when there are about two green lights left (there are usually five total lights).

Depending on which lights are red, we will perform an Inspection I or Inspection II service.

Newer vehicles have condition-based service, or CBS, which the vehicle software calculates service intervals using an algorithm based on various sensors, driving style, average traveled distance, ambient temperature, and other variables. This will actually tell you which parts need to be replaced. For X-drive cars, their transfer case fluids need to be replaced regularly

We recommend performing air and cabin filter replacements every 30,000 miles. Spark plugs on most non-M vehicles should be replaced every 60,000 miles. Automatic transmission service, as well as transfer case and differential service, should be performed every 60,000 miles as well, as part of the Inspection II service. Despite the improvements in synthetic fluid technology, our experience has taught us there is no replacement for old-school maintenance intervals.
