what would my tranny temp be after roughly 10 miles at 70 mph on my truck (empty). I have been watching it to try to see why my mpgs are bad and I may have found something. it takes about 50-60 miles for my tranny temp to reach 170-175 degrees. thought it would run a little warmer than that and maybe reach that temp sooner than that.

does the max tow maybe have something to do with that?

 

Your trans is fine. Your mpg's are bad because you drive a heavy, semi-aerodynamic brick for a vehicle. Check your tire pressures and drive slower. Then your mpg's will go up. It is a pickup not a hybrid toyota prius econobox.

 

I saw a tranny yesterday standing on the street corner but she/he didn't look hot.

 

you know I could sit here and call you a ***** , but instead thanks for clearing up my question.

have a good weekend. anyone else have a real answer for me on what temps are normal.

 

Mine usually get to those temps within 10 miles unless it's colder than a well diggers ***.

 

My truck used to run empty between 170 - 185 all day long. I know the trucks have a transmission cooler but I think you're fine.

 

You seriously think the trans is messed up and returning poor mpg performance, and I'm the *****! The ***** talking to the idiot! I will type this real slow so you can understand, your transmission is FINE. It either works or it doesn't. There isn't much in the middle.

Yes it can take 10 miles or so on the highway to get up to normal temp. About 175 to 190 degrees fahrenheit. It will run hotter when pulling or hauling a heavy load. Over 200 is normal then. Try to stay less than 240 i think it is. Lock out 6th gear and stay in 5th if trans starts hunting for gears. Use tow/haul mode when needed, towing or hauling.

Good grief. Why is common sense, just not common anymore? If all else fails, read the manual. If that doesn't get it for you, take it in to the dealer.

Thank you for calling me a *****, you made my day!!!

 

FYI, if you call someone a name, then you aren't asking a question. You would be making a statement. But thanks for playing anyway! Better luck next time!!!

That is being a *****.

 

My trans temp stays between 199 and 201 on the highway above 70mph, empty. It does take at least 20 minutes to get there, and depends on ambient temperature.

 

Where do you live - outside temps greatly effect my trans temp,reading. Summertime it take 15 miles to hit 190 which is my normal operating temp. Winter when it's below zero my temp,will never exceed 150.
Highway driving takes lounger to,warm the temp.
