Q:

What is the difference between Dexron-II and Dexron-III?

A:

Dexron is the brand name of transmission fluid manufactured for General Motors vehicles; Dexron-II was released in the 1970s, and Dexron-III was released in the 1990s. Dexron-III is considered to be backward compatible with other versions of Dexron, meaning it can be substituted for Dexron-II and other older versions of the fluid. However, as of 2014, neither version of the transmission fluid is currently manufactured or marketed, and the most current version, Dexron-VI, is used in a backward-compatible fashion with GM cars that require either Dexron-II or Dexron-III.

One of the biggest differences between Dexron-II and Dexron-III, aside from their different names and the different years in which they were developed, is the fact that Dexron-II was originally marketed with alternative ingredients such as jojoboa oil. This reflected the public trend toward "natural" ingredients that became popular in the 1970s. Subsequent versions of Dexron-II were released to compensate for the issues caused by the use of inferior ingredients in the original Dexron-II, including Dexron-IID and Dexron-IIE.

Only one version of Dexron-III was ever marketed after it hit the market in 1993, and it was replaced by Dexron-VI in 2005. Some replacements for Dexron-III may be available on the market today, but these products are not officially approved by the General Motors Company.

    What is the difference between automatic and manual cars?

    A:

    The difference between manual and automatic cars is that manual cars use manual transmission whereas automatic cars use automatic transmission. In a manual car, the driver is responsible for shifting the gears as the car's speed changes, but in an automatic car, changing gears happens automatically.

    What is the difference between serial and parallel transmission?

    A:

    Parallel transmission refers to a situation when binary data transfer occurs simultaneously, while serial transmission refers to one in which binary data transfer occurs one bit at a time. Parallel transmission is faster, but more complicated, because each bit travels along its own data path. Serial transmission is normally slower but simpler, because each bit shares a data path.

    What is a shift solenoid C malfunction?

    A:

    When a shift solenoid C malfunctions, it causes a car's transmission to shift incorrectly, which makes it difficult or impossible to drive that car. The shift solenoid is a crucial part of the transmission, which reads computer signals from the powertrain control module (PCM). The PCM tells the solenoid to open and close its valves, allowing the flow of transmission fluid, essentially telling the transmission where to shift.

    What causes a heavy clutch pedal?

    A:

    There are many causes of a heavy clutch pedal; one of the most common causes is a worn out clutch. When the clutch is starting to wear out, it does not spin at the same speed as the flywheel. This creates friction, which requires pushing harder on the clutch pedal to change gears. There are also a few other auto parts that cause a heavy clutch pedal.
