How difficult , any special tools or need a big honkin press? | | | | | Joined: Mar 2014 Posts: 154 'Bolter | | 'Bolter Joined: Mar 2014 Posts: 154 | I did mine using the Novak rebuild kit. It's pretty straightforward. You will definitely need a press to complete the job.

How much smaller I couldn't really say. It may vary from one transmission to another based on how the tolerances stack up, and how corroded yours might be.

It's a small world, but I wouldn't want to paint it.

When I had to work on my gearbox a few years ago, I made a stand just like what they show in the 2nd pic. Made working on the tranny, so much easier. Still have it buried somewhere in one of my truck tool boxes.
