What's normal Trans and Coolant temp for 2020 Ram towing

[David776895]

Hi everyone, took my trailer into the Colorado mountains last week and trying to figure out what's considered normal temperatures on the newer Ram trucks.

2020 Ram 1500, 3.92 rear axle ratio.

pulling my 6000# 28' travel trailer I have not seen over 200* I dont think..I stay 69/70 and have not been in mountains with it but texas hill country type terrain. oil temp around 235-40. I use the full synthetic from free dealer oil changes. going to pull it up to lake murray in ok. tomorrow so will make a note of the temp since will be a heat advisory day.

Making them Eagle heads work... Hope you are running a quality synthetic oil or short(3K) intervals.

That ZF 8 speed not even breaking a sweat though.

It's running full synthetic from the dealer.

Your last comment, you are saying my numbers are fine? Thanks !

The German's designed that engineering marvel to operate at 185 degrees!

Your transmission temp and oil pressure are identical to mine, while not towing. So that looks good to me.

Your engine temp is what I see sitting there idling, I hit that temp and then the fan comes in and drops it down. I don't remember what I hit while towing.

Your engine oil temp is quite high, don't know if that's normal while towing. While driving unloaded on highway for long time, mine hits about 222.

I had 8,200 lbs on my 2020 Hemi 1500 4x4 with the 3.92’s a couple weeks back and I went up some big a$$ hills and saw about 250 on oil tempe and 225 on coolant. Same as yours essentially, motor pulled strong as hell and didn’t feel overworked. Temps dropped right down after hills. I’m also in az though and it was 109 degrees when I towed.

I had no issues with the engine pulling, it was fantastic. Just want to be sure i am not doing long term damage.

I do not think U R out of operating range, but that OIL got high. IF U constantly tow a lot, U may want to think of extra oil cooler. Other than that, make sure U R running quality Synthetic Oil.. IMHO..............

If U R running 5W20, with those temps and mountain,s, U may want to go to 5W30, again all IMHO.

That trans temp is ideal , long life ahead.

Higher engine temps when climbing mtn passes is normal and only temporary.

The biggest concern is the transmission as it starts to varnish at higher temps and EXPENSIVE to replace.

Flash point is 350 degrees so you are not even close. ATF temp will be highest when pulling a heavy load up a steep grade at high elevation (thinner air). I would only be concerned if on the back side the temp did not start to fall back into the normal range.

Good idea to use Tow/Haul mode if the weight of the truck and trailer load exceed 75% of the GCWR for the truck. It is designed to keep the ATF temp as low as possible under the circumstances.

It's a good idea to use the Tow/Haul mode just about every time your towing. It keep the engine in the power band better and keeps the engine from lugging. These 8HP transmissions will run in the 200°F range without issues(there are several known worked hard for over 200K), the fluid used tolerates heat a lot better than ATF of yesteryear.

just got back from towing my #6000 trailer to and from lake murray in ok. sunday..heat advisory day..tranny temp. topped out at 195*. mostly ran at 188* and oil at 235-240* return yesterday mostly the same...heavy traffic so ran at 66-68 instead of my usual 70ish
