Seann,

I also have my transmission fluid tested by the GM transmission tech at every engine oil change.., one of the main reasons I have the synthetic engine oil/filter changed at my GM dealership.

Bob

Transmission Temp. & Towing

Keep trans temp under 215 degrees and change it every 25 to 30 thousand miles and your transmission will last a long time.

Jim, if you can't monitor transmission temps via the trucks on board info screen, [if applicable] just keep an eye on the temperature gauge in the instrument cluster. Make sure it stays in the normal range because engine coolant is primarily responsible for cooling the entire power train. Remember, as stated above, outside air temps and terrain will play a big role in how hot the transmission will be. Again, check it when you stop for gas or something and make sure it doesn't smell burnt as Seann said. Also, make sure you stay within the trucks payload capacity. Payload; Sticker weight-people-hitch-gear etc. One last note: 5000lbs is no match for your hemi!

Here is a guide I found when I used to pull my trailer with a 1500 Suburban, my Suburban had an auxillary transmission cooler and kept the oil changed regularily. I also had the Scangage II to monitor my transmission temperature.

Because of the Scangage and this temp guide, I realized the transmission on Suburban was the weak link on my vehicle and ended up selling the Suburban and buying my Ram 2500. I no longer have transmission temp problems.

One thing to consider is where your trans temp is being measured. If you are getting a temp from the pan, then what you are measuring is not the hottest the fluid is getting. You want to make sure to allow for this. My Ram doesn't have a gauge (yet), so I just take it easy and closely monitor the fluid condition. Our Tahoe liked to hang around 180* to 200* with a bit higher (up to 210*) on long grades. One thing I learned was that dropping a gear to increase RPM's also increases flow through the tranny cooler and I saw my temps drop off pretty quickly. Keeping overdrive off helps a lot too (and is recommended for towing with many rigs).

Your rig is pretty new, but it doesn't hurt to be pro-active with the tranny fluids. I do a drain and fill every other oil change or so. This only gets about 1/2 the fluid, but I figure none of the fluid should be getting to old or "used up" using this method.

With 5k and the 3.92 the Hemi shouldn't even be breaking a sweat!

Bob...and others,

When you change the tranny fluid/filter do you just drop the pan and change the filter and what fluid is lost there, or do you have all of the fluid pumped out and replaced?

Thanks,

Ken,

I incorrectly stated "change" in my post, but I actually have my transmission "flushed" (pumped) at my GM dealership. One can have their tranny fluid changed in a single session, but I believe it leaves behind the old fluid in the torque converter and possibly some of the trans cooler (it may very with each vehicle).

Bob

hey! I am not familiar with transmission temperature but getting to know it since we'll be towing this summer and wanted to know what the normal temps were
We are at 56 000 km (a little over 30 000 miles) and we had the transmission flushed at the Dodge dealer. I have been looking at the transmission numbers on the EVIC and although it is cold here right now, around 35 degrees outside, the transmission temp were up to 185 degrees without towing, driving on the highway. This seems high. Is that normal?

To be that cold out and not towing 185 is high IMO. What kind of temps were you seeing when towing in warm weather?

Hey! I got this from a guy in Ram forums : "That's normal range. When you consider you engine operates around 200F, it's not bad at all."
So how about when towing, would I expect temps to go up much or does the Transmission (heavy duty on the Ram 2010) cooler kicks in?
