My Trans (48re) lost second gear while I was on vacation in Florida. Dropped the pan and threw some pressure solenoids at it in a desperate attempt to get it home. I pulled a 32' enclosed gooseneck down so was a little desperate. Upgraded gov solenoid and ducer didn't fix anything. Everything looked nice and clean (I service the thing every 30k) did the whole dealership exploration, but I'm too poor for that big money. Left the trailer there, sent the truck to a reputable Trans shop with instructions to build it and took Dad's truck home. Only had 165k miles on it. Do some towing a few times a months like the pics below... Not sure why it gave up so soon. Told the Trans shop to plan on 800ft-lbs up hill with 20k pounds behind it, foot on the floor with warranty... He said "got it, see you in a couple weeks"
