My Dennan unit was out of the truck for a couple of years while We overhauled the 230 and did a few upgrades to my 48 B1. I have reinstalled it but it will not upshift. We confirmed power to the solenoid and can hear it actuating. We jacked up the rear end and tried to get it to upshift under no load conditions without success. Its full of fresh fluid. Any further thoughts before taking it out for disassembly?
