the green t/c lock light is on on my truck and wont go out any ideas on why? and would it be bad to drive my 2000 h1 with this on?

 

is your t-case in HL or L?? you should try to move it into H and jiggle the lever.... then accelerate let off and accelerate again the light should come off. If you are still in HL or in L, yes thats a bad thing if you are driving on pavement.... otherwise, it might be a bad sensor....... just remember, the label and the lever don't always line up...
