30mi after tranny rebuild and SM/clutch install the TC started popping into neutral.
I pulled the NP241 apart and this is what I found:
broken spring retainer
worn range shifting fork-worn through the plastic retainers and into the aluminum and had just started hitting the planetary.
Planetary looks great, like new.
a retainer/snap ring was out of it's groove on the outer side of the output.
What do you suppose was the cause? did the snap ring move and allow movement of the shafts to the point of the fork wear and broken retainer? Did the FW/Tranny work have any affect on this? If this was just a coincidence that it happened now, I wish it would have happened 40 miles ago as I was getting ready to do the clutch and found the other mess!!
