Hot Corvette
Hi!
I'm a 55 year old guy who finally cratched thar itch and bought my vette. It is a 2002 Red Convertible with LS1 and 4 speed auto.
I've owned camaros,firebirds and Trans Ams. But I've always had my eye on a little Red Vette.
I'm doing my own maintanence on it, I've changed the oil and I just changed out the thermostat and coolant
I know the LS1 engines run hot, I know the cooling fans kick on at about 228 and 235 respectivly.And they work like there supposed to.
What's got me concerned is the transmission temperature.
Outside tempratures around south Louisiana get pretty hot. Last 2 days the temperatures hovered around 97-101 degrees Fahrenheit.
While driving around with AC on, Temps on the tranny held about 10-15degrees below engine temp, which was 220.
One of the first things I did when got the car was replaced the transmission with a GM Rebuilt. The original one was slipping and GM owns this new one for the next 3 years/100,000 miles.
Do these temps sound about normal?
Should I install an aftermarket Transmission oil cooler? I've heard these will void a warranty.
Where should I tie it in? On the top transmission line going into the radiator or the bottom one?
Any info you pros can give me will be appreciated.

I don't have an answer for your question but you may get more responses if you post this in the Tech Section. There is a lot of people in there that know their stuff, not saying the ones in the general section don't but you may have better luck there.

On hot (90+) and humid days stuck in traffic, I'll see 219 on my tranny temps. Don't much like it but it still holds together. I have offend wondered how hot is too hot. If anyone knows the limit, I'd like to know. Thanks
