A clutch is a mechanical device which engages and disengages power transmission especially from driving shaft to driven shaft.

In the simplest application, clutches connect and disconnect two rotating shafts (drive shafts or line shafts). In these devices, one shaft is typically attached to an engine or other power unit (the driving member) while the other shaft (the driven member) provides output power for work. While typically the motions involved are rotary, linear clutches are also possible.

In a torque-controlled drill, for instance, one shaft is driven by a motor and the other drives a drill chuck. The clutch connects the two shafts so they may be locked together and spin at the same speed (engaged), locked together but spinning at different speeds (slipping), or unlocked and spinning at different speeds (disengaged).

P0740 BMW Code The code is common in BMW vehicles experiencing transmission troubles. The P0740 diagnostic trouble code references a torque converter clutch circuit open condition. When a solenoid valve tries to operate and the TCM senses a voltage drop, this code is recorded. The vehicle may experience hard shift and may not shift into…
