Mr 64,

I've not replace the parts in the K1 and K2, yet!

The continuous O-rings seals for brake band piston 1 and 2 since I bought a new B2. I do not have to deal with it.I'll deal with B1 when I get to it.

372k miles that is worn out transmission. look for bluing of metal mating parts, bearings...

I'm replacing parts 126,185,197,275,410,189&122. The rear case 394 has a plastic piece that is not available, but you have to buy the whole new rear case.
