What is the proper Trans temp

[ladorn45]

Hey Everyone,

I installed a gauge that has a trans temp. I been reading that the temp should range from 170 to 200. I drove my Tahoe around for awhile in 45 degree weather and the temp did not go past 150 basically stayed at that spot and never went over is that normal. Just want to make sure i got the right temp spot so I can upgrade the face and needles. This is a 2001 tahoe.

This is from Google for an idea............My trans temp on a 80 degree day is 183 around town.

mine got up to 210 when pulling my trailer loaded with 2 Harleys in the summer

The trans fluid flows through the radiator and the temperature of the fluid depends upon a few variables.

Generally the fluid will heat up as the radiator heats up. It depends on the amount of air flowing over the radiator. If you are going a steady 45mph in 45F outside temps then you are cooling the fluid down possibly faster than it can heat up. In that case you wont see very high gauge temps. I only see 180-220 when towing or when it is a hot day and I am parked idling with no A/C on.

Do this. Take the outside temp. In your case it is 45F. We know radiator heats up to 210-ish. So all we need to do is just figure the temp halfway between the two temps. It should be about 130F. That's what your picture shows.

Yeah during winter in the mountains where I live that’s about average for my trans.

According to the manual:

"The normal operating range is from 180°F to 200°F (82°C to 93°C). At approximately 265°F (130°C), the message center will display a TRANSMISSION HOT message and the transmission will enter a transmission protection mode. When the transmission enters the protection mode, you may notice a change in the transmission shifting patterns. The transmission will return to normal shifting patterns when the transmission fluid temperature falls below 260°F (127°C)"

Mine runs 120-145 normally. Will get to 165-170 if I'm in stop and go or towing

Trans temps were pulled with a scan tool

...drove my Tahoe around for awhile in 45 degree weather and the temp did not go past 150

Nothing seems to be amiss at that outside temperature.
