Well the old box locked itself into 3rd on Friday.
I've got a recon box on it's way, originally promised for Sat, but unfortunately late, now promised for Tuesday.
So I bought Matt P's old box which had been sitting in his garage for a month or two since his engine transplant.
I fitted it today with some help from Nova X, Cavlad and Simon P.
By 10pm it was ready to rock. I also greased up the powerflex bushes and sorted out lower strut brace problem.
Only one problem! Neutral is in fact 5th gear (limited top speed will be 136 indicated (lower final drive ratio)) and all other gears are locked solid. I smoked the clutch seeing what they were.
So now I'm going to wait until Tuesday and fit the recon box.
I think that the box must have seized up being sat in the garage for a few months.
