best way to test duty c solenoid and valve body phase 1 4eat

Recommended Posts

I have had some experience repairing various fails of the duty c system. recently I had a solenoid fail mechanically bleeding off atf failing to lock the clutch packs yet the solenoid ohm tested fine and did not throw a tcu code. this all resulted in front wheel drive only


this video depicts how I use air pressure to open the valve body and make sure pressure is applied to the clutch disks. 




there are several writeups on how to get to the tail section but I do plan on doing my own with pawl instructions! the one I did find in USRM the guy had a loose one he HOPED would not lock up on him.... GEEZ X.x
