Ps2cho, it's been a few years since I disassembled my 722.3, so take this with a grain of salt. I tried my best to forget all that "fun".

1. I can't remember a B3 "Band", and couldn't find it with a quick memory jog looking at the tranny dwgs. There are the B3 brake clutch plates (4 soft plates) which are the big ones that control Reverse and 1st gear.
These are right in the front, around the K1, and should definitely be checked.
Per my experience and study here, these are the first to go. Mine were trashed, which is why I went into the tranny.

2. The K1 clutch uses smaller plates. I discovered mine had too much clearance even after new soft plates were installed, so I purchased a slightly thicker end plate from the dealer to tighten it up a bit. Check the plate spacing when re-assembling just to be sure it's okay.
You said K-1 kit, so I assume you mean new soft clutch plates.

3. There is a B-1 band around the K-1 clutch that I had to remove to get the B3 and K1 out. The servo has to be released (under the side cover) and it's under about 40 pounds spring pressure. Getting the cover plate and c-ring on while holding the spring down is kinda tough. Rig a lever using a bolt in the nearby threaded hole as a fulcrum, and it can be done without special holding tools.

4. You may know that there is a K1 shift-feel kit, consisting of a couple of little springs, that goes into the valve body. I installed this later, as I was still not able to get that perfect 2-3 shift i wanted. It worked really great.

5. You do have one of the tranny assembly manuals that are available online here? Do a search and download one if you haven't yet. You might also search some of my old posts about my journey into the B3 and K1, and the search for the best manual. at my age, it's good to have the old archives to refer to - Ha.


Oh, when you replace the engine rear main seal, loosen the seal cover/holder bolts, but before prying the cover/holder out, try to separate the oil pan gasket from it by gently sliding a razor blade just above the gasket. If you can leave the gasket attached to the pan without tearing, that will improve the chances of no leaks in that area. But still coat it with gasket sealer when reassembling.
