Acura dct transmission1/2/2024 Under power, accelerating up to highway speeds (and beyond), the feel was that of a DCT: fast sequential shifts.īut during a slow rollout from stop, the torque converter absorbed any surging or irregularity in torque delivery to the wheels in a way that few conventional DCTs have so far. With its energetic 201-HP i-VTEC engine mated to a quick shifting 8-speed Dual Clutch Transmission (DCT), youre up for an invigorating driving experience.

The continuous running of the belt among the pulleys doesn’t interrupt power flow to the wheels. CVT, on the other hand, doesn’t lag far behind and is also fairly efficient. The company also announced an eight-speed dual-clutch transmission (DCT) for transverse installations, which it intends to use in larger and higher-performance models in the Acura range and the upper ends of the Honda lineup.īut Honda has added an interesting fillip to the increasingly common DCT technology: a torque converter like that in a conventional automatic to smooth takeoff and low-speed downshifts, the points at which regular DCTs become jerky as they must slip their clutches to mimic the behavior of an automatic. Among all the types of transmissions, DCT is the most efficient as it doesn’t let fuel go to waste during shift in transmissions. A continuously variable transmission operates more efficiently and smoother since it doesn’t delay or jerk when shifting gears, but it offers slower acceleration and is better at low-speed. Honda has three models of DCT transmissions, a 7-, 8-, and a 9-speed version, which is available on different models of their vehicles. The shift solenoids control the torque converter lockup valves (solenoids A and B) and they shuttle shift valves. The five shift solenoids are normally closed, on/off design. There are eleven solenoids in the valve body (figure 1). One clutch for odd gears and one for even. Unfortunately, the electronic and hydraulic control for the Acura 8-speed DCT is back to being fairly complex. Like an automatic transmission, a Dual-Clutch Transmission (DCT) does not. DCT stands for Dual-Clutch Transmission, and it is, for all intents and purposes, an automated manual transmission that uses two clutches to engage gears. Honda direct-injected and turbocharged 1.0-liter three-cylinder VTEC engineHonda says the two will produce "excellent fuel economy," which is really their primary purpose-to replace larger, heavier engines of the same output.īut given the variance between real-world gas mileage and the EPA testing results on Ford's growing line of EcoBoost engines, it may be wise to wait and see how they behave in customers' hands before taking Honda's fuel-efficiency claims at face value.
