automatic transmission

There have been a lot of technological advancements, and breakthroughs in efficiency to make modern cars, trucks, and SUVs so much more fuel-efficient than their counterparts. While engine design certainly plays a huge role, automatic transmissions have come a long way as well, contributing greatly to the gas mileage of your vehicle. From Harold's Used Auto Parts Inc in Philadelphia, PA, here are some ways transmissions have changed to meet the demands of fuel efficiency.

Electronic Control - Modules, sensors, computers, and solenoids all work together to make sure today’s automatic transmissions are shifting right where they should, every time. By honing in shift points, RPM can be kept regulated, as well as the power needed by burning fuel to accelerate or hold the desired speed. The vehicle is constantly monitoring conditions, so the transmission is in the correct gear and shifting at the correct moment at all times.

Better Response - Modern transmissions are much more responsive and waste less energy than their predecessors. A certain amount of efficiency is lost through the fluid coupling of automatic transmissions since they aren’t directly mechanically engaged with the engine. Modern transmissions are nowhere near the slushy, unresponsive slush boxes of yesteryear - in fact, they’re beginning to surpass manual transmissions in terms of responsiveness and efficiency.

More Gears - Finally, modern transmissions simply have more gears to choose from, making them faster, more responsive, and more efficient. With 8, 9, and even 10-speed automatics taking the place of the 3 and 4-speed transmissions from just a couple decades ago, we’re seeing a renaissance in how automatics are designed and utilized. For modern transmissions, you need professional technicians that have the knowledge and equipment necessary to keep your vehicle shifting strong.

No matter your repair or maintenance needs, we’ve got you covered. For the best transmission service shop in Philadelphia, PA, call or stop by Harold's Used Auto Parts Inc today.
