An Auto transmission specialist has come a long way since they were first introduced to transmissions decades ago. While the basics of the transmission shift is still the same, the mechanical improvements have been considerable. Today, your auto transmission offers a smooth shift of the gears for a seamless ride. And, when you use your trusted Sunshine Coast mechanic, you can keep the transmission running smooth for years to come.
You may wonder if the basics of the automatic transmission are the same. If not, what are the differences that make having one so worthwhile? The answer can be found in what was learned from the original auto transmission units installed in vehicles decades ago.
What are the Mechanical Differences in Auto Transmissions from Yesterday to Today?
The basic mechanics of the automatic transmission is the same. The similarities include the use of drive chains, torque converters, pressure pumps, clutches, planetary gear sets, and valve shutters that have proven to be reliable.
Arguably the biggest difference between automatic transmissions / gearbox of yesterday compared to today is the inclusion of computer design methods. By using computers, the overall design of the pressure pumps and torque converters have improved dramatically.
Another important difference is the use of different materials. The improvement to metal coatings or finishes for a smother transition of gears to bolstering clutch friction materials. The more advance lubricants has meant the transmission operates smoother than ever.
The knowledge found along the way has improved the services for a transmission flush or rebuild and upgrade and repairs.
Torque Converter
If there is one outstanding difference, it is the introduction of the torque converter lock-up clutches. Before, the gearshifts were initiated by changes to the intake manifold vacuum. While this works reasonably well, it relied on engine speed to make the appropriate changes. Since the points of shifting were never optimal in terms of fuel consumption, it meant that a vehicle burned more petrol as a result.
The torque converter lock-up clutches use a different system which means that the shifting is now far more accurate in terms of optimal fuel consumption. The result is that automatic transmission vehicles are now virtually identical in terms of fuel consumption compared to manual transmissions.
In practical terms, the changes mean that using computing power has replaced the vacuum control system. Considering that computers in vehicles have the power of desktops computers made about a decade ago. This means that there will be more advances made which makes automatic transmissions even smoother, more reliable, and with greater fuel efficiency.
In fact, the development of electronic systems not only for the transmission / gearbox, but for the engine itself represents the greatest advancement in auto technology over the past 30 years. With such electronics that control ABS, throttle, braking, cruise and stability control, the sheer amount of wiring and computer power is quite awesome. But that does create another issue.
