I hate to ask what has been probably answered a dozen times but all of the searches I've looked at have lots of different answers so here goes.
I have a 96 LT1, stock, no mods, newly rebuilt transmission, recent oil change (Mobil 1), and replaced optispark and water pump by the previous owner approximately six months ago. Based upon the optispark change I assumed some change of coolant (Dextron II). The car runs great so maybe this is a silly question but I've just never owned a car that seems to vary so greatly in temps.
Oil: 195-220 usually holds with 5 or 10 degrees of water temp.
Water: 190-230 the 230 holds in town and drops back with A/C and fans going but I never see 180s like a lot of folks mention unless it's a quick trip. I'm fine on the highway with the temp steady at 195-197.
Automatic Transmission: - here is my big concern; 185 to 230. I'm always in the 200 range and I get concerned that in town driving hovers in the 220 to 230 range consistently. Everything I read about ATF fluid says that's bad but a few posts on this forum say it's normal. I can stay at 190 - 207 degrees cruising at 70ish but I notice it takes a long time for the temperature to start dropping back down.
I would be interested in everyone's actually temperatures just to see if I'm in or out of the ballpark. Average temperature outside is 85 to 95 degrees.
My next project appears to be flushing the coolant but I want to be sure I'm not wasting my time. Thanks Rick
