4 speed tranny stuff for the V8 and high HP /6 crowd, Pictures Options

Here is the latest gearbox I am building for someone. It is an F-N-X-HBf box and I wanted to show how easy it is to lock out 1st in a 4 speed box. I have heard that there are people that charge a chunk of change to do the same thing....I think that is wrong as it is way easy. All you need is a rear gasket, tubing cutter and a section of 3/8" copper tubing (1/2" shown as I bought the wrong size).

Here is the FNXHBf stack (Ooo, purdy).


Here is the shift rod end for 1st that needs the sleeve to lock it out. I removed 1st gear completely other than the gear on the input shaft as you need it for reverse.


And here is the section of ~2" copper tubing. You need to keep the slider for revers. It looks like the sleeve will hit the slider, but it is just the angle of the pic.

For those of us running a locked out first gear and taller gears: Is it easy to revert back to 5 speed and gear ratios for a turbo Suby?
