To put the tranny in the car you will have to very carefully work to get it up and over the driveshaft and the passenger side half shaft without damaing the oil seal on the differential casing. I used a rag to help out on that a little bit. After a lot of fiddling around and grunting you'll probably get it in place. It will not seat all the way up to the engine though more likely that not. Both times that I worked on this I could not get the half shaft to seat easily and had trouble with the driveshaft as well making it quite difficult. What i did was get it as close as possible and then used the 19mm bolt on the back side by the rear engine mount and the 19mm bolt on the front side by the front engine mount. I threaded them both in a little bit and progressively tightened them down until the tranny seated. Do this carefully so that you do not pinch, bend, or break anything.
After you get the tranny seated, just put all your bolts back in and parts back on in the reverse order.
Fill the tranny up through the front fill location which is a 23mm bolt as well. Make sure you do it with the car on the ground and level. Fill it up until a little drips out the hole and you should be all set. It took about 3 quarts even for me.
Good luck with your install!
