 +''​ClutchComponent''​ is a mandatory ''​Powertrain''​ component. It is always second in the ''​Components''​ list.\\
 +  * ''​ClutchComponent''​ can be bypassed by setting the output of ''​EngineComponent''​ directly to the desired ''​PowertrainComponent''​ but this is not recommended as it will cause stalling in most cases.
 +
 +== Manual Control ==
 +  * Untick ''​Is Automatic''​ to use manual clutch.\\
 +  * Clutch can be controlled through ''​Clutch''​ axis - check [[Setup:​Input|Input]] section for more info on setting up axes.
 +
 +== PID Controller == 
 +PID controller is used to control ''​Clutch Engagement''​ when ''​Is Automatic''​ is true.\\
 +  * More about PID controllers [[https://​pidexplained.com/​how-to-tune-a-pid-controller/​|here]].\\
 +  * In general default clutch settings should be adequate for most setups.\\
 +  * ''​PID_Coefficient''​ can be adjusted to slow down or speed up clutch engagement.
 +
 +== Slip Torque ==
 +  * When ''​Has Torque Converter''​ is false ''​Slip Torque''​ is used. Otherwise, clutch will use ''​Torque Converter Slip Torque''​. \\]
 +  * Slip torque for a normal clutch should be a bit higher than the maximum engine torque. Usually a few hundred to a few thousand Nm.
 +  * Too high ''​Slip Torque''​ will result in grabby clutch.
 +  * Using too high ''​Slip Torque''​ values can result in torque spikes when clutch is suddenly released which can impact solver stability in extreme cases.\\
 +  * Values near zero will result in engine spinning up as if the clutch is not engaged due to clutch slip.\\
