How many miles: right at 117k

Were you able to remove the harness without breaking any of the plastic clips on the solenoid connectors? Yes everything came out with no problems. I even have a spare tranny with about 100k on it that I pulled the harness out of with no breakage

Chain stretch was within specs according to how the manual has you check it.

I have a 300M input shaft, I'll put in a hardened 4th clutch hub shaft, I'll be going to a single chain set up with stock gearing. The input shaft may ultimately overkill by leaps and bounds, and I probably dont need a hardened pump or output shaft. I think Trannyman would agree too. But I am contemplating getting them because I am anal about that kind of stuff and since I got it all tore down my thoughts are going along the line of why not build it to exceed anything I'll ever need. But we'll see how that goes I have yet to purchase the pump or output shaft.
