Yes, it has been a very productive day.
Started at about 1pm. By 6pm, we were pretty much done, all bar the ATF, Catalytic converter, and the snag we came across when the prop coupling wouldn't fit

So, quick trip to halfrauds, to get a deep reach 30mm socket. I then sorted out the prop coupling problems, while Marie set about removing the gearbox sumps. (I don't think she appreciated my taunts about finding a thrust washer in the new gearbox sump

)
With the gearbox sumps cleaned out, re-fitted with an initial ATF fill, filter changed, and the prop happily connected, we set about fitting her brand new GM) cat converter. Bit of a pain, but got there between us.
We started her up and there is drive in forwards and reverse gears, so that's enough for tonight.
I must say, this is the first time I've been accompanied by lady under an omega with a hair full of ATF

The hardest part I found in the whole job was getting the bolts through the flex plate into the torque converter, we used some good grease to hold the bolts in the sockets. The location of the access hole in the block on the X20XE is shocking, it is a really fiddly job, and if you drop a bolt you are completely stuffed. We had a good production line though, I was swearing at the bolts while Marie was fighting against the compression strokes.. and eventually we got the six of them in

Jobs for tomorrow.
Re-check and rectify ATF level.
Fit different exhaust bracket on the gearbox to support the exhaust (this box came off a V6)
And that's all the under-car work done.
Following that, we are doing cambelt kit, aux belt, and water pump, and then a full and thorough service.
We did notice a manifold stud missing when the box was off, so we rectified this, and it's now silent from cold 8-)
We've had really good day at it, very productive all bar a couple of managable snags, and FANTASTIC weather for the job.
Tomorrow will be an easy leisurely day by comparison.
Am now sitting in Marie's living room, sinking some stella - Early start tomorrow

Oh... and I strongly recommend the axle stands we bought for this job, they are excellent !
