What is normal temp for 4l60E ???

[tyhuck]

What is the "normal" running temp for a 4l60E just cruising down the highway?

 

I recently installed an automoter gauge on mine and I want ot make sure its working properly. I had a gauge on my 01 S10 that stayed about 180 - 210. This one is reading about 125 - 150. Granted, its been between 50*f and 60*f so it isnt gonna read as high as the s10 did in the summer, and the S10 was a whole different animal (6cyl, compact space, less air flow) compared to my current truck (V8, more air flow, factory trans cooler), which is why Im asking for input from other 1500 owners that have the ability to keep track of that.

 

Im not worried about it overheating. I just want to make sure my new gauge is reading properly.

That is the normal range in my son's '07 5.3 'Hoe with an external fluid cooler.

I want to say in the summer mine runs in the 160 to 210 range but I can't remember for sure.

Normal for me under regular driving is about 50ish*C (120F). The highest I've hit is 110*C (230F) once, while towing 6000lbs on a long uphill stretch, in 32*C (90F) outside temp. I have the factory trans cooler.

Sounds normal to me. 230 and above is no-no land. Most transmission guys will tell you that normal trans fluid temp is near or abouts the same as the engine coolant temperature at that time. My 6L80 is never near my coolant temp but I digress.

Yeah, I start to get concerned about the time it reaches my engine temp, but my engine temp stays stable at 190. Doesnt the fluid start to break down around 210 or so?

 

The S10 used to worry me in the summer, but it seemed to hit 180 and hold steady regardless of load, terrain, or speed.

 

But, it sounds like the guage is working properly. I could have checked it aginst my wife's Tahoe, but she has a 6l80E and I didnt know if they ran at different temps.

110C/230F was as high as it went, and only for about 10 min overall. After the trip, I had it checked out during regular service at GM, and the fluid appeared perfectly fine per the tech. I was impressed. But yes, obviously you shouldnt make it a habit.
