DCT(Dual Clutch Transmission) Learning
1. | Learning Overview and Purpose
A. | Checks gear shift precision and normal clutch operation in the finished car to ensure accurate DCT(Dual Clutch Transmission) control by the TCM.
2. | Conditions that Require Learning
A. | Perform learning when replacing DCT assembly, dual clutch, gear actuator, clutch actuator motor, and/or TCM.
B. | This comprises 3 steps. Step 1. Gear Position Learning Step 2. Clutch Characteristics Adjustment Step 3. Identification of Gear Shift Timing
C. | Tool: GDS or G-SCAN

Inspection
In principle, the transmission oil is maintenance-free, and no exchange is required. But it must be inspected and replenished every 4 years or 40,000 miles.
1. | Park the vehicle on flat ground and turn off the engine.
2. | Remove the oil filler plug (A), and check the oil state and oil level.
3. | If the oil is dirty, loosen the oil drain plug (B) and drain the oil. Then fill with new oil.
Replacement
In principle, the DCT oil is not changed under normal driving conditions. However, under harsh driving conditions, it must be changed every 80,000 miles. Harsh driving conditions are as follows:
• | High frequency driving on rough roads (bumpy roads, sand and gravel roads, snow-covered roads, and unpaved roads)
• | Frequent driving on mountain trails and inclines
• | In case the vehicle is used as a police vehicle, taxi, or for commercial or towing purposes
• | Frequent high speed driving (over 170 km/h)
• | In case of driving 50% or more of the total mileage in hot temperatures above 32°C(90°F) and congested traffic
1. | Remove the drain plug (A) and drain all the oil. Then replace the drain plug.
Drain plug tightening torque: 58.8 ~ 78.4 N.m (6.0 ~ 8.0 kgf.m, 43.2 ~ 57.6 lb-ft)
The drain plug gasket must be replaced with a new one.
2. | Remove the oil filler plug (A) and fill with approximately 1.9 liters of new oil. Then replace the removed oil filler plug.
