I totted up, it took 4 hours total.
I also listed each thing I did and what tool I did it with. Saves a helluva lot of time next time crawling out from under the car for the next size spanner
I had to pull out the dissy, disconnect the rad top hose and loosen the motorplate bolts to allow the engine and box to tip back far enough for the bellhousing to clear the bulkhead. A bit scary doing it on my own!
Cos I didn't want the trans to drop suddenly, I lay under it... This would have been fine but as it slid gently onto my chest, it got wedged and pinned me under the car
I wriggled free and dragged it out, job done!!
By the way, I can highly recommend going to your local furniture reclaimers and hunting down 1m square office carpet tiles, £2 each at mine. Makes crawling under a car almost a pleasure

No-one will believe you...
