Regarding the o/d in second gear. I have it in my TR3 (2nd,3rd and th4)but not in my TR4 (3rd and 4th). I seem to recall reading some place that after a certain serial number (or the A-type o/d) it is not recommended to have the 2nd gear option. Something to so with the strength of the unit to handle the switch at full power. But again I can't remember exactly where I read this. I just remember there was a reason that I did not add it when I converted my TR4 gear box to one with an A-type over drive, even though I had all the bits and pieces to do so.
I am interested in what others have to say on this.
