At the finish line and alittle confused. When I took the transmission apart I had 8 checkballs, and one was larger than the rest but I was unsure if it was above or below the separator plate. I can see that the plate has taken a beating where the one checkball goes in the case so I’m leaning on the larger one going there. But I’m also hearing some shift kits come with a larger checkball for the spot closest to the oil pump. I do have a checkball seat repair kit coming too for peace of mind but I just wanted to ask what experienced builders think.

Going from Trane to Honeywell Home, everything makes sense except the orange and black wires that go to AUX 1 on my old thermostat. I’m assuming they go into O/B and AUX on my new one but I don’t know in which order.
