Picking it up is one thing, bench pressing it out whilst under the car is a very different prospect altogether
True, but I've no real intension of trying to manually lift it at all if I can help it. With the LC I usually jack the front up, then the back, then the front etc whilst supporting the other end on wooden blocks. I do have a transmission cradle thingie that attaches to a trolley jack, but it's a bit unwieldy to use under a car on ramps/axle stands.
Oops, I should have typed lb,s not kg,s. Don't suppose you have the means to weigh it ? Does it currently have fluid in or not, as that would make quite a difference ?
I'll try and remember to bring the bathroom scales in tomorrow. AIUI it's got new filters, thrust washers and some oil in it. Will obviously need the level checking once it's in the car but it's sealed up quite well at the moment so I'd prefer to avoid getting covered in ATF until/unless it's absolutely necessary. Even so, if there is 2L of ATF in it, that's only going to add 2Kg/4.4Lbs to the overall weight, which in the overall scheme of things weighing more than 20Kg isn't that relevant.
I've also got a V6 3.0L Auto engine sat here (needs a bottom end rebuild). Might weigh that too just for giggles.
