Have a '99 F350. wanting to diagnosis torque conveter slip. Have access to AE. Just don't know how to use it for this procedure. Any help?

 

AE uses J1850 PWM protocol to talk to the truck, then it's a matter of selecting Torque Converter slip or TC slip (can't remember which is the exact name). Make sure you have RPM, Gear, and Speed logging with TC slip. There are times when the TC is supposed to slip, and times when it's not.
