<P> The 4L60 - E family of transmissions use 2 shift solenoids , initially called Shift Solenoid A & Shift Solenoid B , later changed to comply with OBD II ( On Board Diagnostics revision 2 ) regulations to 1 - 2 Shift Solenoid & 2 - 3 Shift solenoid . By activating and deactivating the solenoids in a predetermined pattern by the PCM , 4 distinct gear ratios can be achieved . The shift solenoid pattern , also sometimes referred to as solenoid firing order , is as follows ; </P>
