Hi,
Aside from taking them apart, how could I tell what gears are in what tranny??? If I open them up, are there numbers on the gears that I could find without taking it apart further??? I may just put each one in the car, drive it and see based upon speed/tach what I have.... Any ideas??? Rich |

I gave up on the letters. I count the teeth. I mark one tooth with a paint marker and count from there.
A lot of the times.. I mark the top of the tranny with what it has in it.. I have seen Brad Mayeur do this also. B |

You could put the tranny into each gear and count the revolutions. The R+P is the constant. Mark the input shaft and turn the output flanges.

That is "different". My guy's have at least 1-2 tranny's with 904 main shafts or custom shafts that allow 3rd gear to go in place of 1st... so they have 5 "race" usable gears. Have to push/pull the car to grid or shutter it in a third gear.
If we have a box with first.. we use it. B |
