I have a '95 GT Convertible. It was originally an automatic tranny car, but just before I bought it, it was converted to a T5. I have 265/35R18 on the rear. I believe the gear in the tranny is the stock one, but Im pretty sure the gear in the dash is for the Auto Trans. I am about 20% over on the speedo reading. When I am going 75mph on the GPS, my dash reads 90mph. I just need to know what gear I'm supposed to have in the dash, and what gear color Im looking for in the Tranny. ~Thanks!
You don't change the gear in the dash (not even sure if there is one) when you do the swap, you change the speedo gear that goes in the transmission. You need to make sure you've got the one for the t-5 and not for the AODE still. I believe you need the yellow 18 tooth gear but I would double check that, unless you have a different gear in the rear end. I've got 3.73s so I had to replace the speedo drive gear as well as the speedo gear when I did my T5 swap.
