What is Dual-Clutch Transmission in Honda Cars?
DCT represents Dual-Clutch Transmission, and it is, in every practical sense, an automated manual transmission that utilizes two holds to draw in the next gears. One grip for odd gears and one for even.
Honda has three models of DCT transmissions, a 7-, 8-, and a 9-speed rendition, which is accessible on various models of vehicles. DCT is used in bigger and better execution models in the Acura range and top models of the Honda lineups.
But in general, most Honda and Acura sports cars do have no DCT. The sole Honda badged model with a DCT framework is the second generation of the NSX model, promoted under the Acura brand in North America, and elements a 9-speed DCT transmission.
Other Acura models with DCT are the original TLX, however just the models with 2.4-liters inline-4 motors, and ILX models with the 2.4-liters inline-4 motors. Additionally, RLX and MDX models sent off in 2014 accompanied the 7-speed rendition of Honda’s dual-clutch transmission.
Common DCT problems and How to Fix Them
The most widely recognized Honda and Acura 7, 9, and 8-speed DCT problems are low speeds increase, the transmission feeling like it is stuck, unpleasant shivers and vibrations at low velocities, and transmission movements to impartial during a drive. Almost all of this Honda’s DCT transmission issues can be followed by the ill-advised activity of the DCT.
Clients frequently assume that it works in much the same way as fully automatic mode and anticipate that it should act in basically the same manner. However, wrong thoughts produce unforeseen outcomes. The reluctant activity of down or upshifting and certain jerkiness while driving at low velocities was brought about by somewhat off-programming of the transmission shift.
● Lack of acceleration
It happens that Honda with Dual-Clutch Transmission car owners complain that their car does not give enough acceleration, which is not expected when overtaking another car. This causes surprising and possibly perilous circumstances while converging into the expressway traffic, as you could do it excessively sluggishly and risk being hit by the approaching vehicles.
This issue is well-defined for the models with 8-speed DCT, which highlights a force converter planned to streamline vibrations in the lower gears, not the faster gears. The reason for this is that the clutches of the torque converter are not sufficiently “broken in,” yet in addition explicit settings in the Powertrain Control module (PCM).
This is the sort of thing when you need to take your vehicle to a dealer center, as it requires an update of PCM settings and making the break-in procedure on the torque converter.
● The transmission gets stuck between gears
Seemingly the most widely recognized issue with Honda’s DCT is the sensation of the transmission as though being stuck between gears while attempting to speed up. A few proprietors describe it as a transmission slipping. That’s what the issue is, like some other piece of the system, DCT must be heated up in a cold climate before it can work ideally.
The genuine reason is that individuals would turn on the motor and step on the gas pedal in cold weather. The appropriate solution is to work your vehicle as it ought to be the climate. Turn over the motor, sit tight for 10 to 20 seconds for the liquids to fire heating up and streaming, and afterward step on the gas pedal.
● Spontaneous switching of the gearbox to the neutral position while driving
While driving an Acura with a DCT framework, one potential issue is that it can unexpectedly move to neutral. Usually, these are Acura 8-speed Dual Clutch problems. There are two possible reasons for this problem.
The first reason for this is the flawed shift solenoid and possibly likewise the transmission liquid polluted with mud. To fix it, you need to supplant either only the solenoid or additionally the transmission liquid.
The second reasonable cause is the transmission wire configuration issue, present on other Honda, and Acura transmissions. Likely, the manufacturer did not design well the crimp connectors. The solution to the problem is to replace the connectors.
● Unpleasant Shivers and Vibrations at low speed
For some proprietors of Acuras with DCT extremely irritating shivers and vibrations create while driving at speeds under 40mph or while remaining in rush hour gridlock. Usually, it is noticeable when the motor is under 2,500 RPM.
Most regularly, this is brought about by problematic torque that keeps the transmission too high, typically fourth. It prompts the torque converter to lock up and causes exceptionally irritating vibrations. Only replacing the torque converter in your Honda will help here.
Conclusion
As we have seen, Dual-Clutch Transmission is not characterized by many problems, but such transmission has its characteristics. And it should be emphasized again that many problems with such a rare but reliable transmission arise due to the inattention of car owners.
But if the problem is really in the system, due to the poor quality of the parts or something else, then only the replacement of a specific part in the car saves the owner of Honda or Acura.
