I have a C-30 tow truck the transmission has a PTO coming off the flywheel for winch ... it appears to be the same bullet proof trany that I grew up with .. I have yet to dig into anything yet.. I am just getting it running after 20 years of sitting in a yard ... my question is ... I cannot find second... sitting parked I should be able to run all of the gears .... yet it goes into granyy fine pull straight back for second it seems blocked then into third ,fourth and reverse all seem fine ...anybody know what I should look for?
