The clutches are Honda part # 22500-HL6-A01 and it uses the same clutch assembly on both sides. These currently cost around $325 each. If you ever have to replace one, it is pretty much guaranteed to be the primary clutch only. The secondary clutch is only used as a startup clutch if the primary clutch fails and the emergency valve is closed. If you need to replace the clutches, see the clutch replacement page.

Operating Noise / How a DCT Works

If you don't know how a DCT works: it is basically 2 separate manual transmissions mated together at the input shaft. One transmission runs the odd numbered gears (1, 3, and 5), the other runs the even numbered gears (2, 4, and 6). The primary clutch is connected to the odd side and is also the starting clutch. The secondary clutch is connected to the even side. When you step on the accelerator, the primary clutch engages, once you reach enough speed for 2nd gear, the computer switches clutch pressure from the primary to secondary. When ready to switch to 3rd, the computer will use the shift motor to shift the odd side over to 3rd, then it will switch the clutch back to the primary. And so on and so forth. It can cycle through gears extremely fast.

Shifting is a 2 part process and very mechanical, because of this there is a lot more noise associated with shifting. Clunks, crunches, snapping, and banging sounds are completely normal. Driving more aggressively will actually decrease the noise, so don't go easy on it, it likes to be driven hard. Getting more miles on the machine will also quiet it down, your first up to 500 miles you can expect to be especially noisy.
