Normal transmission temperatures?

[MICA4R]

I've read 140F to 200F is the normal range.
I do a lot of highway driving in 95+ degree temperatures.
Do I need a trans cooler?

Why would you even ask that? If 179 is your peak, which is well below even coolant. You are fine.

What is the upper limit?

I'm itching to do another mod and spend some $. This is a great place to help justify it.

What is the upper limit?

I thought it was 200F

Do you tow anything? If not, it really isn't necessary.

No I don't tow

but today the temp outside was 98F and my trans was hitting 189F on flat roads

Im just curious how you got Torque to display tranny temp. I can not get method 1 or method 2 to display information and method 3 just duplicates the coolant temp. I also have the torque scan add on app and ran a PID scan with no luck.

Still isn't anything to be concerned about.

Yea. That isn't a high temp reading. I have a v8, with the aux cooler, and when it is 99 degrees where I live I get similar temps.

220, higher, then you start to worry. But you won't see that unless your towing a lot, up a huge hill, for a good bit.


It really, really, really, really, sounds like your just looking to blow money on something. Doesn't need to be this.

The trans Temp is far more externally linked and the designers knew that. It is going to be a much more flexible system temp wise.

Did another up and down mountain run last night, driving the wife to a company retreat through the TN/NC mountains.
Only difference was this time we had had to do it at night due to logistics. It was 60-58 degrees the whole time and my trans temp never got about 158 degrees.
