I just bought a 2002 GT and the previous person put a short shifter on, I was curious at what brand and everything so I pulled it off and first, the black insert was not in, and second, after a quick Google search this shifter is listed as a T-5/T-45 shifter online. Could this have done harm to my transmission? Should I go get it looked at? Luckily the person I bought from gave me the original shifter too so I have that back in.
