Fluid temperatures

[jwuonog]

Sorry if this is a stupid question, but what are the normal operating temperatures for oil, coolant, and transmission temp?

Do the different drive modes have an effect on the temps as well? I'd imagine sport mode with its higher line pressure would cause some increase in the trans fluid temp, and with the coolant being a shared system, those two would increase as well.

My trans runs about 175-180 unless it’s really hot out and I’m flogging her. Then around 190-195. Coolant seems to run right around 190-195 almost all the time. I’m tuned with some mods and I like to put her through her paces somewhat regularly. A bigger intercooler really helps keep air temps in check but don’t know if that helps cool anything else.

Thanks. I recently saw about 210 for all 3 after doing some pulls and sitting in traffic. It seems like they're all in operating range, but I feel like most people run a bit cooler.

I think these are all within normal operating range...but this was after a short 15 min drive with a few pulls. It just seems high for what I didm

All well within range. Trans fluid is good to 220-225 before thermal breakdown. My coolant gets over 200 at times. I wouldn’t worry about it.

I was on the highway for about 45 min, going 65 to 95 at different times, with a few WOT pulls. I was around 200 to 210. After I got off, temps climbed to 220 as I sat at different red lights and drove about 30 mph in between them.

I know I'm still in operating temperatures, but it seems a bit high. I hear about other people who never see higher than 180. I wonder what is causing the difference.

After driving some more, I've observed that my temps are just fine on the highway, but start to rise once my speed is reduced. I think my radiator fan might not be working, I'll have to look into it.
