I had some occasional hard shifts starting around 95,000 when I bought it- mainly in tow haul mode. Around 135,000 I noticed a couple slips, but then it wouldn't happen for a few months. Finally, one day it kept binding when put in drive and it would lurch when it let go. About 50 miles later, it started slipping really bad in the middle gears. I drove straight to a shop and they said it was shot and I probably wouldn't make it 100 miles back home.
