A few months ago, I pulled out my valve body for some work, and now I have some questions about this thing for the next time I go in.
I removed the main plate gasket set entirely. It was already cracked on removal around the accumulator section. Like the accumulators pounded it to death. I was told that removing the gasket would make for firmer shifts, and it did a little bit. But what about the smaller plate gasket set on the upper valve body? Should I remove those too? I left them because I wasn't sure whether they are necessary.
Two of the accumulator pistons dropped out with the valve body. The o-rings aren't in the best shape. Do any of you know what the dimensions are on the piston o-rings? What material should the o-rings be made from?
Is the accumulator modification really as safe as all the guides indicate? Safe being strictly in terms of transmission longevity. Has there been any signs of the steel dowels causing wear against the casting or the pistons? Is there any way they should be designed to limit potential damage?
I replaced the checkballs with torlon balls of a similar size. Except the steel ball. Is that one safe to replace with torlon, or will that cause undesired behavior? It didn't look worn at all. The rubber balls also didn't look very worn, but they also didn't feel like they were made of rubber anymore.
I'm sure I asked some dumb questions, but I don't know much about transmissions. My understanding is pieced together from green books and websites. This thing sure is interesting, though. I hated automatics until mine broke and I had to learn how it works.
