Clutch safety switch

they like to mess with u on ecu's
Pontiac solstice when the variable timing solenoids code it puts max pressure for transmission so the trans hammers when it shifts to 2nd

cry fwd goes into limp mode (2nd) to get u home but it the trans doesn't have 2nd it goes into neutral and u r walking

gm if voltage is low the ecu blames solenoid b in the trans.
