As said be careful when you rebuild, there are 2 lots of splines and a dog that all need to be engaged, often it can feel like it's in and not be, that's when the pump gets bust.
I'd advise anyone doing this to measure the location of the torque converter with the whole lot still assemebled, you can access it throught the bottom of the bellhousing or the round access hole underneath. You MUST be sure it's fully engaged before you attempt to refit engine and gearbox.
I was surpried though, i thought the TC would be bigger, it's not much begger than on my 2.0Capri :-k
