But it will be so gratifying when it does work - it was for me and I was plenty nervous as I had put in a new clutch as well and another poster had put in his clutch plate backwards so I started getting anxiety that I had done that too! Getting the tranny in and out is a big part of the job what with the extensions needed for the top left bolt and the angling needed as you get it in position and manuevor the input shaft forward. I would not have wanted to have to pull it out again by any means! I'm just an average mechanic without lots of experience and I pulled it off so I say if you're up to the challenge, go for it.

The encouragement is great and much appreciated. For me I don't ever get under the car with jackstands. Just don't feel comfortable when I'm pulling on something or torquing on a bolt. I have large solid paving bricks (1'x1') that I may use and my plastic car ramps (rated for 15,000lbs). I'm thinking one or 2 large bricks under all the wheels and lowering the front of the car onto the ramps on top of the large bricks should be the safest and get the height I need. With jackstands at the right points just in case. I used the ramps in the past when doing work under the car and they are strong and solid (wide and long).

Never use bricks or cinder blocks, they are too brittle under small contact area pressure :!: If a cinder block must be used in a pinch, use it in the same orientation as it is in a foundation (i.e. holes vertical, not horizontal). But I cringe every time I hear of people using masonry blocks for car support. Scares the crap out of me.

Bricks are solid and only about 3" thick but my jackstands are rated for 3 tons. So they are probably good. We'll see. Maybe I'll just remove the engine and tranny so I can clean up everything! :D Scope creep!

I have never used a press for either of those operations. The 1-2 gear bushing usually slides off with light tapping.
I just put the the input shaft with bearing on top of the vice and hammer it out with a soft mallet (could use a hammer with a piece of 2x4 on top of the shaft). Same thing could be done with the 1-2 bushing if it did not move easily.
