Slow shifts out of first, flashing OD light

Yee-up. I reckon that would do it...

Didn't help that all 8 bell housing bolts were loose. I thought I torqued them down, but maybe not?

Yup, that was it. Pump bolts were all good, but I apparently hadn't torqued the bell housing bolts down to spec. Now it's good'n'tight, and the rig is running stong!

Update - 2023.0910: Exhaust leak, mostly squashed. IAC sticky resulting in low/faltering idle when stopped, cleaned and resolved. Heater Control valve leaking, replaced. Aside from those minor issues, still running and 1k driven since transmission rebuild.
