The 4L80-E ( RPO MT1) is rated to handle engines with up to 440 ft·lbf (597 N·m) of torque. The 4L80-E is rated to max GVWR of 18,000 (Axle and vehicle dependent) The 4L80-E uses 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.
