Dual Clutch Transmission Diagnostics
The dual-clutch transmission produces a drivetrain that has the efficiency of a manual transmission, but the ease of use of an automatic. Compared to automatic transmissions, one manufacturer claims a 5–10 percent reduction in fuel consumption from just this one feature.
Complete Clutch Replacement: No Noise, No Comeback
Diagnosing clutch and manual transmission noise can be a difficult diagnosis. There is no way of attaching a scan tool or looking into the bellhousing while the clutch is under load. Clutch diagnostics requires logic and understanding of how the parts interact.

Slipping Clutch: Improper Flywheel Step and Cup Dimensions
Slipping is one of the most common clutch related concerns. A slipping condition can occur after years of service or immediately after installation of a new clutch and is caused by various scenarios. One of the most commonly seen and easily prevented causes of slipping is improper step and cup dimensions (Figures 1 and 2)

Causes of Clutch Failure: Diagnosing Chatter
One of the most difficult clutch-related problems is chatter. Chatter is sometimes difficult to diagnose because it has many root causes, and some of them may not seem related at first. Chatter can be detected as a pulsing or a grabbing sensation that resonates into the vehicle cabin and originates from the driveline or chassis/suspension.

Clutch Repairs Made Easy: Making Use of Something We Normally Throw Away
Clutch replacement is a job that normally takes a good bit of time, and we want the job to go right the first time. Whether it’s a 4-wheel drive Ford F-450 or a Chevrolet Cobalt, we don’t want to do the job twice, but that’s exactly what may happen if the clutch installation does not
How Does a Dual Clutch Transmission Work?
Dual clutch transmissions are like having two manual transmissions shifting together while being controlled like an automatic transmission. This is the transmission of the future because it is lighter than an automatic and is just as efficient as a manual transmission. Instead of a linkage connected to a shifter in the cabin, the shift forks
