i feel really late with this responce. but my water temp is normally running at 170F, my oil temp is normally around 200-225 depending on the weather and how hard i run my car and my tranny temp has never been checked.. none of this is in my volvo this is all readings from my 95 Z28 and the readings from my PC1 caprice are close to the same. i have a 9C1 oil cooler on my Z28 since they had such a retarded oil cooling system on the Fbody and my oil cooler and tranny is mounted behind the openings for my fog lights, what thermostat are u running, and what temp is your fans set to come on? mine are set to switch in at 190F but i also have a switch which if i recall is an SLP item that adapts into the harness so u can turn your fan on and off whenever u want and it will still cut on from the sensor when it has to, and i have a 160tstat. and i also run synthetic ATF in my z28 but its a 6spd so thats y i never actually adapted a temp guage to it.
