Default Re: overdrive question

I have a update for you. I have repaired the entire electrical part of the overdrive. It is working as it should. all tests show the solenoid works perfectly when the governor grounds the relay kicks in and the solenoid engages. Job well don! OHHH not so fast. I'm thinking the interior rings of the OD are not positioned properly. When starting in first gear the truck is starting off already in OD mode even in first gear it stays in od till over 28 mph when the governor grounds the relay the power transfers to the solenoid and it kicks in properly. However this action pulls the OD unit out of OD and into standard mode. Just the opposite of what should happen? Any ideas? I'm thinking that during a previous repair job the transmission was moved out of position for the cogs to properly engage? Does this sound possible?
