The TCC lining also was changed, from paper to a high-carbon content lining to stand up to the extra friction and heat generated during PWM operation. Harness Connector Removal Tool for 4L30E, 4L60E, 4L80E, 4T40E. There are 2 shift solenoids in a 4l60e (1-2 and 2-3), and both control up and downshifts with fluid passing through them when commanded to do so by the computer. Another way to test your shift solenoids is to check the ohms of resistance with a multimeter. Within the EC3 game plan it is generally undesirable to fully lock the TCC. This blocking modification has been embraced by some builders of high performance or heavy towing units, even without a trouble code to conquer. A second TCC solenoid was added to control the regulated apply valve. E: ignition power feed from TCM to solenoids . It is found in both 240 and 260 from 1975 through 1986.
