Shifting a 4 speed transmission - any comments?

Shifting a 4 speed transmission:

I have a friend who has a 1929 6-66 that he has just brought to life. However, he is a little puzzled by the 4 speed transmission. I have tried to help him, as best I can, but I have never driven one either. Can someone explain the position of the different gears - One brochure I have reads" normal gear placement, except low which is latched out??? Anything that you should watch for or do or not do?
Don would appreciate all answers. Send them to me as he does not have a computer.

Re: Shifting a 4 speed transmission - any comments?

Shift pattern on 4 speed is using circle with north to the top or to the dashboard. First; left bottom south-west quarter. second; left top north-west quarter. third; right bottom south-east quarter. top or fourth; right top north-east quarter. Reverse further to the right outside the top quarter. push against spring resistance then slot into far northeast position.
I have also had differential modified (Range Rover centre) machined to replace low ratio crown wheel and pinion from 4.4 to 3.5 which allows highway cruising at 80 KPH @ 2000revs. I believe the original specs said 3.9 ratio but mine may have been replaced long before coming into my possession. Effectively allows the top gear to be an overdrive. Third will still pull most highway inclines and the lower gears are adequate to move the vehicle on steeper climbs.
