01 4r100 no reverse
my parents have a f350 which now has no reverse. it has a reman sticker on it, 230k on the truck but no idea on mileage on the tranny. shifts 1st through 4th fine, no slip. Tc lockup works just fine. no codes found with my solus scanner. when shifted in reverse it will move back about 2 ft if reved above 2k and then nothing. Am I looking a trans rebuild or is there something I can check and repair with in it the truck?

There is a slight possibility that the feed bolts between the valve body and case have loosened. But revving it to 2k to get it to move might have made that check moot. If the clutch was partially applying, revving the engine like that for more than 1-2 seconds will totally destroy the reverse clutch. I suspect you need a rebuild, even if you didn't when this first happened.
