Yup here she is ! Drove around all day and avg was around 140-160 city/hwy. I decided to also do a test and hook my 4500lb boat up and back up my 1/2mile long STEEP driveway. Was fairly muddy and was slipping in 4wd(even with the spool lol).. stopped at 223*F and let it idle in N so i didnt burn it up. WAY glad i got the gauge... Hit 170 a few times idling around parking lots and stuff as well(empty).

 

Was supposed to include whats my max safe temp? Like as in when should i toss her in neutral and let her cool?

 

That's why a temp gauge is so important. You stopped at let it cool, as I do when plowing. Without it, the tranny is getting badly abused if it's allowed to be at high temps for long periods of time. I'm putting a B&M cooler on it sometime this summer before plow season. Maybe sooner, as I have to tow a Bobcat around a few times this summer. That's if I can ever get the rusted in solid hitch out that's in it now.

 

Time for an additional aux trans cooler with it's own fan??

 

Drove it hard a few times running code 3 to a few calls... Hit around 185* at its peak but cooled to 175-180ish. Driving around i see 130-150*. Have it in test port 4 on the gov sensor.

 

i have the derale cooling pan with the temp sensor in the pan bung...I see 97-100 on the highway. But once I get the truck off the highway (after 1 hour) and into stop and go city driving, the temp goes to 140.

160 was the highest I have seen in my truck since the temp gauge install. I am also running full synthetic (valvoline) ATF.

 

Is that test port the one on the passenger side front most port? That's where mine is.

 

I have been thinking about this myself. I tow 2-4k lbs on a daily basis. I want to upgrade my trans cooler at the same time.

 

Yup thats where mine is.. i can take a pic if youd like.

 

The test port is not the best location. Should be in the cooling line coming out of the tranny. Then again, I think I've told you that. And to get one of these. At least your getting a temp reading though I suppose. As most don't have a gauge at all.
