it has the plastic red gear inside and there isnt anything wrong with it it is the metal gear that goes inside the housing that is bad? stick your finger in the speedo hole and try and move the red gear .
I wonder if someone put a newer gear in on a older metal gear style shaft . . . .
if so I have the metal ones also .
and just a fyi : I want to know what the end problem is . . . . my 88 th400/205 combo I swapped in my plow truck years ago don't work . I did cable / good used tested speedo unit . just never took apart the case back yet to figure out why . so your my test mule![]()
