I believe my 88 gt has a t5 in it.I just bought it three weeks ago.I was shifting from second tothird annd when I did the shifter just went limp and I was able to move it like it was in neutral.I let out the clutch just a little to see if I was in gear and it started to grind. So I towed it back and to the cover of the knob and the upper case where the four Allen bolts are is loose and the shifter will not go in any gear. Any ideas
