I rebuilt my first 200-r4. The trans works good but the shift point for the 3-4 shift is at 50 mph under light load. The gov. is for a GN but the valve body is from a 86 grand prix with 3.42 gears. The marking on the VB is CRZ. Does anyone know if or what can be done to lower the shift point but leave the other ones (1-2, 2-3)where they are at. I would like to lower it to below 45 mph under light load. I do have my original BRF valvebody but would rather not take the original trans apart.

For what it's worth...
Try checking your TV cable adjustment. If I adjust the cable using the factory procedure, it doesn't pull itself out far enough. Thus, my shifts are harsh, and my car will not go into 4th gear until about 48-49mph. If I adjust the cable per the factory method, and then pull it out just a millimeter or two more, everything works OK.
