7.3L Power Stroke Technical Info
Hey all, the wifes 02 superduty 4x4 with the 7.3 started chattering in reverse, but only under load. Anything over 1/4 throttle gets it to chatter and slip. Driving foreward, it doesnt matter if your full throttle, or idle, loaded with 20k lbs or empty, it will NOT chatter in any foreward gears...
