Gradual EMCC Release
NO EMCC
Under No EMCC conditions, the L/R Solenoid is OFF. There are several conditions that can result in NO EMCC operations. No EMCC can be initiated
due to a fault in the transmission or because the TCM does not see the need for EMCC under current driving conditions.
PARTIAL EMCC
Partial EMCC operation modulates the L/R Solenoid (duty cycle) to obtain partial torque converter clutch application. Partial EMCC operation is
maintained until Full EMCC is called for and actuated. During Partial EMCC some slip does occur. Partial EMCC will usually occur at low speeds, low
load and light throttle situations.
FULL EMCC
During Full EMCC operation, the TCM increases the L/R Solenoid duty cycle to full ON after Partial EMCC control brings the engine speed within the
desired slip range of transmission input speed relative to engine rpm.
GRADUAL EMCC RELEASE
This operation is to soften the change from Full or Partial EMCC to No EMCC. This is done at mid-throttle by slowly decreasing the L/R Solenoid duty
cycle.
