21+ 4L80E Tcc Wiring Diagram Background. Transmission wiring diagram i have a 92 f. Tcc manual wiring diagram 4l80e.
Can i simply swap the tcc wire (now brown) from its existing position on the pcm to the non pwm position and the corresponding term on the trans plug? How do you test the tcc solenoid on the 4l60e wiring. I have a 1985 gmc 1500 5 7l 700r4 suburban without ccc i.
This system works with 4l80e and 4l85e automatic transmissions, as well as 4l60e, 4l65e, and 4l70e automatic transmissions from 2008 and earlier.
