Triumph Repair: tr6 tranny switches

Question
i read somewhere that there is an ajustment for the switches. my trans. has 4 switches, one down below ,one on top and one on each side.

Answer
I only know of 3 switches on the gearbox. 2nd ON and 3rd/4th on for the overdrive and a back-up light switch. I don't remember any 4th switch.

I will check with friends in the restoration business and let you know if I find there was a 4th switch.
