The rain stopped and the sun came out at about 6 this evening, so got back under the car, finished bolting up a few brackets etc and pumped the fluid back into the trans. Took it for a drive and it's all working the way it's supposed to, even the Alpina flash is still doing the business New (to me) engine and gearbox transplanted successfully at last - it's only taken me about 13 months and I don't know how much $$$$! Next time (shudder the thought) someone says they'll do the swap for $1500, I'll jump at it!
