Got a buddy a few towns over I've been trying to help out with his tranny. He had it rebuilt for P1811. It was good a little while, then P1811 showed up again.
After the original rebuild, here is what has been done by the tranny shop in an ongoing effort to keep P1811 and harsh shifts from popping up.
I'm not sure of what the piston was. He just e-mailed me that little list. Probably accumulator piston or something.PCS 3x
Valve body 2x
some kind of piston
surecure kit
Anyone have any ideas? Keep in mind the above parts were after a rebuild.
