No, it's not. But the K1 and K2 are replaceable just by dropping the pan. Apparently the valve body (approx 1 zillion screws) has to come out for the rest. Doesn't look hard.

I only needed better 2-3 and 3-4 shifts, so I bagged the rest of the kit. In hindsight, it would have been cheaper maybe to get the K1 and K2 kits (if there is such a thing as a K2 kit) from the dealer.
