ok so im getting a steady reading of 20/21 oil pressure at idle now.and a good 35 at about 1500 rpms,and it goes up nicely when under a load from there.

trans temp readings went down by about 10 degree's reading just the fluid temp.
what's cool about this location is you can watch the fluid temp and in real time.your not getting readings from a hot trans case.so the temps go up and down much sooner.
im seeing a 155-160 going down the road.this means my cooler is working very nice at keeping the fluid cool,so it doesn't heat up much by the time it comes out and is ready to be cooled more.
it took a few minutes sitting at dunken donuts grabbing a cup of joe for the fluid to reach 170.i think it peaked at 175 or 180,then as i went down the road,it quickly went right back down to mid 150-160 again.so the external cooler really does a number at dropping them temps.

water temp readings went up to warmup at almost 230 degree's and i could tell the thermostat opened up likely sooner than i knew,but temps went back down to 220-225 or so and hung around there.i think my peak was 235 or so.

so the question still remains.where to set my warnings at?
im thinking:
trans temp peak: 200 degrees.
oil pressure low: 10 psi. surely 10 psi would be scary perhaps but wouldn't want it any lower at idle right? at what pressure reading would you say "that's it.shut her down asap and replace the oil pump before damage occurs?

water temp: at what temp is she about to start boiling over? 250-260?
and at what temp should i hear this huge airplane sound of the fan clutch engaging?
