(Making a Two Speed Gearbox From a Five Speed Gearbox)
However, in a manual gearbox shifting between 2nd and 3rd gear is a “dog leg” which is pretty annoying after a while. So with the help of two fellow AEVA Sydney members, one a mechanic and the other a gearbox design engineer, I set out to modify the MR2 gearbox. The process went a little like this:
This is the main shaft having the 1st gear removed. And now 1st, 4th, 5th without teeth. Rebuilding the gearbox with the modified gears. 1st gear gone. 4th gear gone. 5th gear gone. This is the gear selector modified so that it cannot move along the shaft, and with the lug enlarged. This is the modified selector moving the selector shafts together. The end result is a two speed gearbox where we are able to shift between 2nd and 3rd gears directly. The Corolla gearbox reassembled and ready to install.
