Made a little more progress. Managed to get some ATF pressure injected into ends of all three cables. Adjusted with rigging tool and now the low idle shift stall is gone as far as I can test on the trailer. Throttle handle works a lot better. Oil pressure after 1/2hr so far is still hanging close to 40-50 off idle and no lower than twenty at idle. We see what happens at the next water trial.
