[Fot] TR6 gearbox rebuild

[Robert Lang]

 The set that JK used was the late layshaft cluster and then the dolomite sprint 3rd / 4th set. When mixed with the overdrive, you get the most useful gear combos.
O/D 3rd is more for not doing a 3rd to 4th shift on both A and J-types, as is 2nd O/D for the A type. In both cases, while you get the extra gears, you don't really get any advantage rowing through them as opposed to grabbing a gear in a quick burst.
FWIW, 2nd o/d is awesome for an autocrosser.  ;-)

 JK also had a set that he used for O/D gearboxes to make the splits more even.
I am not sure what they were, but they worked well.

JK Jackson had that all figured out for a non overdrive box with the goal to get a better 2-3 spread.

I have a ton of gearboxes laying around, so if there is a combination I should try I’d love to give it a shot.
