Automatic Car Transmission



An automatic transmission is the latest version of manual transmission that was used in cars of olden days. The automatic one changes the gear depending on the speed of the vehicle, thus freeing the driver from the trouble of shifting the gear manually. Whether in US cities like Chantilly, South Riding or anywhere in the world, people always prefer cars with automatic transmission.

Since the popularity of automatic transmission is increasing day after day, car manufacturing giants are coming up with modern cars which have only such gear system instead of the old manual transmission. Recently BMW launched 650i Convertible which comes with an 8 speed automatic transmission which offers a lovely combination of flexibility, speed, and sportiness.

Since the automatic transmission can be considered as one of the most complex piece of machinery, a number of warnings are associated with it which you need to be aware of. Some of them are:

Leakage: If you notice a small pool of pinkish oil on the ground after taking your car out, then it is a sign of a major problem. Transmissions can leak from a number of external seals, some of which are quite easy to repair whereas; others require the expertise of professional mechanics to deal with. This is often overlooked by most US citizens in cities like South Riding and Burke which can prove dangerous in the future.

Shaking: Sometimes drivers experience a shaking sensation especially while driving at high speeds. This may be due to poor engine tune or in most cases can be due to the malfunction of the vehicle transmission. Best would be to take the vehicle to an expert mechanic.

Delayed reverse or drive: When you notice that your car is taking longer than usual to shift the gears once the shifter is put to “D” or “R” then it is a clear sign of a mechanical problem with the transmission. Such delays can be mainly due to low fluid level in the gear box or a band that may require adjustment.

Burning smell: If you get a burning smell, it may mean that the transmission of your car is overheating or the fluid is leaking onto the exhaust. This needs immediate attention of a mechanic.

Automatic Transmission Problems :

Shift speed too high or to low: Throttle and pedal cables out of adjustment.

Lose of drive : Fluid level too low.Drive plate to torque converter bolt fallen out.Internal fault.
