Transmission Temperature Chart
 
1 Attachment(s)
Just thought I would pass this on. The life span of a transmission at certain operating temperatures.

Good info. Measuring transmission temp is one of the hottest topics on the diesel truck forums I visit.

cfsoistman 03-10-2009 12:10 PM

Thanks for the info. This is definitely one piece of information that helps everyone in the forum.

Thanks Wade!!

No problem, I am trying to collect more info on issues like this to pass on. It would be nice if this kind of stuff could be posted on the side of the main page of the forum under a special heading of some kind. I believe that knowledge is power, the more one knows the better off everyone is, I'll admit I am not the sharpest tool in the shad, but I have learn a lot from the members of this forum and has made me think twice.:nansplit::nansplit:

By the power invested in me, I shall make it a sticky.

I'm going to print this one and keep it in our truck

rockwood06 03-11-2009 07:57 PM

I am glad it is helpful, please pass it on if you like it may save a costly repair.:Allinarow::Allinarow::Allinarow:

Unfortunately the temp. gauge on our rig doesn't show actual degrees just that you are somewhere between C and H, thanks a lot Ford! For that reason and because I would like to know actual temperatures as well as fuel flow and such I am considering one of these for our rig:

I would like to have real time displays of what the OBD computer is gathering information on.

I like it a lot, but unfortunately it doesn't appear to support my vehicle. Maybe I'll give them a call and see if they plan a version that will.

My new truck has a D.I.C. system, Driver Information Center. At a push of a botton it will display transmission temp and other items, it will go into alarm if any thing go's out of a safe range. It's a great thing to have, maybe you can add this to your truck. I now have 2,200 miles on the truck and tow with it one time and on the warmest day the transmission temp was at 144 degrees and that was on a 3 hour drive.

This is something that I think should be on every truck and RV, especially a fuel mileage readout. If we are going to do anything about reducing our oil usage as a country we need to be able to show drivers what effects their led foots have on the "stupid pedal" as we call it in Jeeping terms. If seeing that driving 65 vs 60 has "X" amount of difference in your gas mileage then maybe people would start to change their driving habits. The above listed gauge is on my list of wants for our new rig so that I can keep a close eye on the tranny temp and mileage among other things.

rockwood06 03-13-2009 01:11 PM

I agree, the D.I.C in my truck has made me change the way I drive. My wife has the same equipment in her 2007 Chevy Trail Blazer and we both keep an I on things. Most of my driving is back and forth to work and I don' use any of the new vehicles that have the D.I.C system, I use a 1999 Grand AM that get 32 mpg and I check it every time I stop to get gas. With 80 miles round trip to work, I have to keep an eye on things. I even change the oil every month on the Grand AM because of the milage. I am sure it the D.I.C system will be in every vehicle as standard equipment before long. It seems that every time when some thing new comes out it starts out in the high end vehicles and then filters down to where I can afford it, and that's good because by the time I can get it all the bugs are worked out.

If you want to know what the OBDII is measuring for trans temp get a ScanGaugeII. Awesome little unit.

hunt4240dw 03-16-2009 09:06 AM

I have the ScanGauge II also. I have the tran temp. intake air temp, instant mpg, and throttle position. I watch the TPS a lot. It helps to keep my heavy foot lighter adn gas mileage up.

does anyone know or know where to find out what the normal operating temp is for a 2001 dodge ram 1500 2wd ? I towed our gs272 close to 200 miles and all was ok but i cant seem to find anything on actual temp. i know the old girl is rated to tow 7600 lbs and the TT is under 5000 but i guess im just a little anal when it comes to weight.
thanks
p.s. Bamasurveyor, what do you pull your TT with ? ( just asking cause looks like we both got the same kind also do you think i am safe with what i have as far as tow vehicle)

LadyWindrider 03-27-2009 05:55 AM

All vehicles made in the last 10 or more years operate with a 195 degree thermostat in the cooling system. If you're trying to read a factory gauge, which isn't always accurate, anywhere from 190 to 210, towing or not, is normal. Once the temp gets to 220, it's time to pull off and shut down everything but the engine. Let it idle till it cools back down if the overheating is from towing. If the overheating is from a leak, shut the engine down also. As for transmissions, lower is better. Hope for no more than 200. If yours runs hotter, just remember to change the trans fluid a little more often.

MtnGuy 03-27-2009 07:56 AM

The aux. transmission on my F150 is configured so that the transmission fluid goes through that before it goes through the radiator cooler. So I believe that the fluid going back to the transmission is probably the near the temp. of the radiator @ 195 degrees or so.

I have read that if the aux. cooler is mounted after the radiator cooler, then you can have performance problems of the transmission during cold weather because the fluid is too cool. JMHO.

jcarr56506 03-27-2009 08:12 AM

thanks guys
i did the math on the weight of the trailer and truck and i have about 700 lbs of wiggle room. hey mtnguy, have you had any problems puling your 263 with the f-150 ? and what does your trailer weigh and do you think that im overloading my truck ? sorry for all the ?' s but this is the only truck that i have available to pull this beast
thanks

So far, my F150 seems to tow the SV 263 just great....but I only have 300 or so miles on it, as I just got it last fall. I have been tweaking the WDH, and think I have finally found the sweetest setting.

My Surveyor weighs in around 5200 lbs. lightly loaded for camping....food, clothes, and water to added to that figure.

Give us more information on your setup (truck and trailer) so we can see the stats before we jump to conclusions......but my initial thoughts are that you should be fine, but we need to know what the 700 lbs. of wiggle room is that you are referring to. You can maybe start another thread to keep this 1 more transmission temperature related.

JeBa 04-07-2009 09:40 AM

I'll be towing a 2004 Flagstaff 26DS (around 5,000lbs loaded) with my 2008 GMC Sierra 4x4 extended cab - drivetrain 5.3L , 4spd tranny & 3.73 gears (it has the full towing pkg w/ tranny cooler).

Since this is my first "large" tt, I wanted to do a highway testdrive before our first long haul to check out the handling, hitch set up, etc.
During the 12 mile test drive, the electronic readout in the dash for the tranny temperature was reading around 158 - 168 deg F (it got to 178 deg during the back & forth of parking in the yard).

Is this pretty much normal?

I never bothered to check the tranny temp when I pulled my old pop up with this truck (figured the pop up was only about 1,200lbs & there would be none to minimal affect).

thanks,

Jeff
