How can you tell what TKO you have? I bought one used a year ago, and didn't ask too much because i was getting it pretty cheap with the bellhousing etc. Was there a TKO before the 500/600? And how do i find out about gear ratio's etc.? It's 5 degree's (F) outside, so i didn't go and count splines, but could ya give me a rule of thumb? I"d like to know before i go and blow my T-5 this spring.
