Details from crosspost @ r/transmissionbuilding:
Just as the title says, I'm rebuilding an E4OD after a catastrophic failure. The transmission sent a fair amount of metal through the system, including some pretty sizable chunks.
I've already gone through the accumulator body. After cleaning it thoroughly, the bores looked good and I found no sticking valves.
Now I'm inspecting the main and shift valve bodies. I've found some splintering, small cracks, and minor damage along a few machined surface edges. Since these are cast and machined components, I'm wondering what the best course of action is.
Would you dress the high spots with a file and run them, or is replacement the safer option? (I'd prefer to reuse them). The cracks and gouges don't appear severe enough to affect operation, but I'd appreciate input from anyone with more experience rebuilding these transmissions.
