Ahhh a question I understand.....
As much as @Bowie69 would like me to ( he has conspired with others on this forum to steer me in certain directions ) I'm not sold on an automatic, have had no experience with them at all, but I suppose you can say that about a 1uz as well
What I do have is a couple of R380 disco gearboxes, a couple of LT77 defender/110 boxes, a 2a with a series 3 bell housing on it and a series 1 box of unknowns condition
I don't know what the relative strengths are however, the 2a box was behind a 3.5 V8 for over a decade and then a tdi with no issues even when I was doing modified trials with it
So I'm in you hands to a certain degree as to which transmission road to take, my only real contribution I suppose is having half a chance of making it all fit together, something about where there's a will...........
Really appreciate the discussion guys regards Stephen
