Hi guys, so I got a 87 mj column shift , I redone the engine and it runs great!, redone the tranny seal and filter , now the truck won't shift ? Stays in first gear , it shifted fine before the maintance , fluids are good, my question is did I maybe forgot to plug something? Connector ? Or did I just f-up the tranny by replacing fluids and filter? It's just weird it won't shift now, any ideas on what to check or do other than a new tranny? Thanks!
