With few exceptions, cars with automatic transmissions should always be shifted into overdrive, as it allows the vehicle to shift into the highest gear available. While in a lower gear, the engine may work harder to maintain speed and use more fuel.
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.

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.
A:The clutch can burn out over time in a manual transmission car if the driver makes a habit of riding the clutch, using the clutch to keep the car in one place on hills or using the clutch to slow down rather than using the brakes. It is also possible to burn out the clutch suddenly by trying to do a "burnout."
A:One way to silence a squealing belt on a car is by spraying on a belt dressing. Belt dressing works as an adhesive to increase the friction between the belt and the pulley to help extend the life of the belt.
A:Some signs of transmission problems are the transmission refusing to go into gear, the smell of burning transmission fluid and noises coming from the transmission when the car is in neutral. Other signs are gears slipping, a dragging clutch and leaking transmission fluid.
A:Overdrive is a transmission's highest gear setting and helps to reduce wear on the engine under normal driving conditions. The engine will turn over less for the same amount of distance traveled when in this gear.
A:When transmission fluid is low, the transmission tends to jerk or slip when changing gears. The vehicle may also speed to high revolutions per minute while in neutral or without the vehicle speeding up or spontaneously slip out of gear. A burning smell is another sign that transmission fluid may be low.
A:While Free Auto Repair Manuals offers a selection of no-cost service and repair manuals for vehicles by model, including detailed descriptions of components such as the transmission and necessary diagrams, very few sources provide free downloadable transmission repair manuals due to the fact that they are copyrighted material. Online sources such as TradeBit, AutoRepairManuals.biz and Haynes provide a wide range of downloadable and print repair manuals for purchase.
A:Some different types of clutches are the positive clutch, friction clutch, hydraulic clutch, spring clutch and centrifugal clutch. Other types of clutches include the semi-centrifugal clutch and the electromagnetic clutch. These types of clutches are found in power trains that may have automatic or manual transmission systems.
A:A throw-out bearing, also called a clutch-release bearing, works by pushing on the springs of the clutch cover plate. These springs hold the clutch friction plate against the flywheel. This has the effect of releasing the drive from the engine through the gearbox.
A:Cheap, used transmissions can be purchased online from general used auto parts dealers, such as Auto Gator and UNeedAPart, as well as from specialized used engine parts resellers, such as Buy Used Engine. Also, Internet auction sites like eBay commonly offer listings for used transmissions.
A:A CVT, or a continuously variable transmission, is an automatic transmission that replaces conventional gears with variable-diameter pulleys, thus avoiding the need to shift between gears, since the transmission is able to continuously vary its ratio.
A:As of 2016, YouTube and PowerNationTV.com have video tutorials on how to rebuild transmissions used in Chevrolets. YouTube has a series of videos of a rebuild of a Chevy 350 transmission from Gorby Transmission. PowerNationTV.com and a YouTube video by Hiram Guttierez have tutorials for rebuilding a GM 4L60E transmission.
A:The most common problems with the Volkswagen Direct Shift Gearbox transmission system are related to the transmission shifting into neutral or losing power unexpectedly during operation. These issues may arise due to problems with the software or temperature sensors of the transmission system, though loss of power issues may also occur due to buildups of sulfur deposits in the transmission. Volkswagen issued recalls for many vehicles fitted with DSG transmissions in 2009 and 2013 to address the issues.
A:The warning signs of a bad torque converter include transmission slippage and surging, partial loss of vehicular power, problems when attempting to switch gears and abnormal engine noise. According to Cars Direct, these symptoms may occur separately or simultaneously. Immediate service and converter replacement is the only way to prevent catastrophic engine damage.
A:When a timing chain breaks, the camshaft stops spinning and the piston can strike open valves. This bends the valves, leading to catastrophic engine failure. Regular maintenance of the timing chain and replacement when necessary prevents engine damage.
A:Ford transmission identification codes include PEA-AG2 for 1973 E100 through E300 vans with 105-inch wheelbases and six-tooth speedo; PEA-AG3 for the 1974 E100 through E300 vans with six-tooth speedo except in California; PEA-AH2 for the 1973 models with eight-tooth speedo; and PEA-AH3 for 1974 models with eight-tooth speedo except California. PEA-AH4 is the code for 1975 through 1976 E100 vans with eight-tooth speedo, drive gear. The vehicles have C4 transmissions and six-cylinder engines. Ford has an extensive list of codes.
A:A valve body assembly, or simply a valve body, is a mechanism in an automatic transmission that serves as a control center for the transmission. It operates by sending fluid through a maze-like structure which in turn operates the appropriate mechanisms to smoothly shift into the appropriate gear.
