If you forget a procedure with the trans on the ground....wouldnt that be more work to install the trans and find out later...then pull it back down. If you have done this particular procedure, its not that unfeasible to be done in the car. Everything is right there once the cover is off.....and this seems to be one of the more difficult duties of the job.

No sir, you would have to perform the same operation with the tranny on the ground. With the tranny on the ground you remove the bell housing and mid housing and then you can take the whole center diff out. No slide hammers on the end cover, no pressing on and off gears and bearings. Just a few dozen bolts total. Bolts are easier and faster to remove and replace than removing the shafts from the end cover. I mention this because RickyN29 has all ready spent 6 hours trying to replace the output shaft with the tranny in the car and he is still not done. He does not even have the old one out yet. He is not the only person in this position either. In 6 hours anyone can have the tranny removed, the shaft replaced, and the car back together.
In my experience and in talking with others, the hardest part of tranny R&R is mounting it on the block. Using a cherry picker hooked up at the bolts holes on the bell housing for the cable bracket is the fastest and easiest method. I personally have mounted one in under five minutes. With a properly aligned clutch I have never heard of it taking more than 25 minutes.
Reassembly of the tranny will be intuitive. The center diff/output shaft ssembly goes in, reinstall the mid housing, place the front diff and pinion shaft back in, reinstall the bell housing, and finally the shift shaft. While their may be more bolts involved and it can sound intimidating, other than bolts, there are fewer parts involved and a significantly reduced chance of damaging anything. With the tranny in the car, you are disassembling it backwards relative to how it was designed to be taken appart and therefore it is not as intuitive during disassembly or reassembly, and there is a far greater chance of damaging parts.
Based on the number of people who have asked me for help with in car shaft replacement and the kinds parts they are damaging, I believe it is easier, faster, cheaper, and far less risky for the average 3Si member to R&R the tranny. While it is feasible to do it in the car, I have seen too many members, even with the help from threads such as this, whom would have been much better off had they dropped the tranny. They almost never post their bad experiences with this proceedure. That is why I feel so strongly about this subject. If one uses the method of mounting the tranny to the block I mentioned above, there is no difficult part of the job.
