    Steps of Driving a Manual Transmission

    Last updated 5 days ago

    To start a manual transmission car, press the clutch pedal to the floor with your left foot while holding the brake pedal with your right foot, and turn the key in the ignition. Put the shifter in first gear. Now, push your right foot on the gas pedal as you release your left foot from the clutch. Shift to the next gear once the engine speed reaches 2,500 RPMs. Watch the video for more tips that will help you drive a stick shift.

    If you have a vehicle with a manual transmission, then it needs to be serviced regularly to ensure that it is reliable and efficient. Superior Transmissions is a family owned and operated shop in the Washington, D.C., area with 30 years of experience.

    Top Signs That Your Transmission is in Need of a Flush

    Last updated 14 days ago

    A transmission flush is recommended every 2 years or 30,000 for most vehicles with an automatic transmission. But if a problem arises and the transmission fluid becomes contaminated, you may need to get a transmission flush sooner to save your transmission from being damaged. In this article we will overview some of the common signs that your transmission needs to be flushed right away.

    Strange Noises
    If your vehicle’s transmission fluid contains too much dirt, sludge, or grease, you will probably hear a grinding noise, which indicates it’s time for a transmission flush. This may instead be a warning sign that the vehicle is low on transmission fluid.

    Shifting Problems
    Another symptom that the transmission fluid is contaminated with dirt and sludge is when the vehicle changes gears too quickly or slowly. In a manual transmission vehicle, it may be very difficult to shift gears at all.

    Slipping Gears
    A transmission requires a certain amount of fluid pressure to stay in gear. So if you notice your transmission slipping out of gear, it’s probably because the transmission fluid is too dirty, or there is not enough transmission fluid to stay in gear.

    Delayed Movement
    Does your vehicle stall for a few seconds before moving after you put it into gear? Assuming that there are no serious problems with your transmission, this is probably caused by dirty transmission fluid. If this is the case, getting a transmission fluid flush will fix the delayed movement problem.

    Vehicle Surging
    If the vehicle surges forward or backward for no obvious reason, it is probably the result of the inconsistent flow of transmission fluid. Flushing the transmission fluid will result in the optimal operation of the gears and other moving parts of the transmission.

    What Is a Dual-Clutch Transmission?

    Last updated 27 days ago

    Today, cars come with one of two basic types of transmissions, either an automatic or a manual. The manual transmission is lightweight and offers the driver more control than an automatic, but an automatic is easier to drive and in many cases more efficient. A relatively new technology called the dual-clutch transmission offers drivers the best of both worlds. With a two-clutch system, the dual-clutch transmission is able to relegate even gears to one clutch and odd gears to another. During shifting, power delivery is seamless. Dual-clutch transmissions are actually semi-automatic transmissions, meaning you can choose between automatic and manual mode while driving.

    If you have a dual-clutch transmission that needs maintenance or repair in the Washington D.C. Metro area, call Superior Transmissions at (301) 358-6288. Our family owned and operated transmission shop has more than 36 years of experience servicing all makes and models.

    A Quick Look at How Your Check Engine Light Works

    Last updated 1 month ago

    All new vehicles are required to have an onboard diagnostics (OBD) system. This system monitors a number of variables that affect the performance and efficiency of the vehicle. When the OBD system detects a problem that cannot be adjusted, the check engine light comes on and a trouble code is recorded. When you take your vehicle in for an emissions test or to a car repair shop, a certified technician will connect a device to the OBD system. This device will read the trouble codes so that the vehicle’s problem can be pinpointed and repaired.

    If your check engine light is on, bring your vehicle to Superior Transmissions. Our family-owned transmission repair shop has more than three decades of experience. Call us at (301) 358-6288 if you have any questions about your car’s check engine light, and visit our website to learn more about the repair and maintenance services we provide for drivers in the Washington D.C. area. 

    A Look at the Technology Behind Continuously Variable Transmissions

    Last updated 1 month ago

    Did you know that the continuously variable transmission (CVT) was invented before the automobile? Leonardo DaVinci actually sketched out a CVT in his journal more than 500 years ago. Read on to learn more about the technology behind CVTs that allows them to achieve better fuel efficiency than a conventional automatic or manual transmission.

    Pulley-Based CVT
    The pulley-based CVT is the most common type of CVT. Unlike traditional transmissions, which have fixed gears, the CVT has a pulley that gives the transmission an infinite number of possible gear ratios, without discrete steps or shifts between gears. The CVT comes with a number of microprocessors and sensors that help the transmission select the best gear ratio given the current driving needs. To adjust the gear ratio, the two cones of the pulley move farther apart or closer together.

    Toroidal CVT
    Some vehicles made by Nissan and a handful of other manufacturers use a Toroidal CVT system. The components of the Toroidal CVT are comparable to those inside a pulley-based system. Instead of a system of pulleys, this CVT comes with discs—one attached to the engine and another to the drive shaft. Rollers found in between the disks act like the belt, transferring power from one disc to the other.

    Hydrostatic CVT
    The CVTs previously mentioned are frictional CVTs. They work by changing the distance between two rotating objects to achieve a specific gear ratio. Instead of using friction to vary the gear ratio, a hydrostatic CVT uses pumps to vary the fluid flow. When combined with a planetary gearset and clutches, a hydromechanical transmission is formed, which is ideal for all-terrain vehicles and tractors.
