Anyone know what would cause this? Not mine, it' happening to a friend of family. Apparently it stays in OD all the way to a stop, and you have to manually put it in first in order to get going again. Apparently has no other issues, no slipping, fluid is good, no "fluid hot" warnings, etc. Speedo reads accurately. Truck is an GMT900 Tahoe (would guess about 02ish), 122k, second trans. Occurs occasionally (and not easily repeatably) at outside air temps > 95*.
