I got a CEL today when i started up my car and the only thing i noticed that was diffrent is my shift from 1st-2nd i got a B&M shiftkit on and i installed it correctly with the heatshrink connectors and whatnot it was on for a good 2 months so i dont think that is what is causing it so could it be that i need to do a tran fluid change would this cause the CEL? i got 60k miles on it if that helps at all

It shouldn't. I posted on your thread in the maintenance forum.
