As far as I know, 3rd reaches around 115. My speedo reads 120, but I know its off. I made a small program in VB that gets pretty close to determining the top speed of a gear. I fed it info and it gave me 115mph. This is with lockup on, and I have yet to do the final drive gear swap. With lockup off, the car acts very odd when it hits 6464 RPMs, and it won't shift, but it'll only do that if OD is off.
