tranny temps

I know this has been brought up a couple times,but after a search with no results, I'm concerned with some tranny temps. I drove the truck 10 miles(empty)and was showing 196,ambiant temp was prolly 80 degrees.Isn't this a little high.I also recall towing 10,000 at a ambiant temp of around 95,tranny temp showed 196

I tow a 13k 5th wheel and I usually run around 205 to 210 loaded and in the 195 range unloaded. I also thought it was a little high, but I guess not

Be Safe

Isn't DieToRemain the same guy who called the coolant temp gauge a "dummy" gauge. I can tell you for a fact that it's not. It's a digital readout showing the exact temp. I've tested it with a temp gun.

The tranny needs to be at about those temps in order to shift properly. You only need to worry about it if it goes over 220. That's when you start burning your fluid.

Yeap, I,ve seen several guys talk about the 220 mark,compared to the7.3 these numbers I'm seeing are high.

I posted this same question a few months ago on the tranny temps. Mine runs at 195 ish all the time. Thats on flat Florida land though, so far I havent hit any mountains yet. It stays the same temp pulling a 11k fifth wheel around 70 - 75 mph. But like I said, thats all flat land pulling, no mountains yet. Even in stop and go traffic it stays the same too.

Im guessing its all good.

No issues with 196....I get the same with my F450 in 99 degree weather.

Asked my tech about this a week after I took delivery, he checked with Ford, all is good.

It's a dummy gauge on 7.3s. LOL

That does seem hot, but maybe the new trannies just run a little hotter?

My tranny temps don't seem to change a lot in the moutains, but my oil temps do climb while I am climbing a grade. They will climb from 200 to 230 on a good 8% grade

I believe these trannies have synthetic fluid from the factory. Synthetic fluids will tolerate higher temps.
