Symptoms? Mine problem started when it "missed" first gear when I shifted to drive.... then it just wouldn't shift till about 4000 rpm.... also wouldn't shift into OD. All happened quickly, but managed to limp it into my mechanic...Rebuilding the tranny as I write this. These were the symptioms, and as usual, tranny's can die quickly, and or malfunction sperodiclly. Now I really can't complain as there is 230,000 miles on my transit.
