Several months back I posted a "NAG1 Tech Alert" in the T1N "write-up section". The posting covered contamination issues with the the 2 transmission speed sensors and the hyd./elec valve body's circuit board.
I had a phone call a few days ago from a group member in the great lakes area. If I recall correctly-50K on his 3500, used in his service business, very heavily loaded, aggressive driving, ATF change at 30K.
He began experiencing transmission problems (50K) and a Malfunction Indicator Light in dash cluster. Repair shop suggested a replacement transmission based on finding (what was actually normal!) sediment in pan.
He had not seen my alert posting but had someone else drop the valve body and discovered its circuit board was contaminated and shorting the solenoids. He replaced (he may have been able to clean) the circuit board which was contaminated with normal metallic debris, normal-considering the severe duty. Doktor A
