Tranny Temp

[SSMtC05]

I just put in my Spartan tuner about a week ago and On the gauges Ive been watching my trans temp as well as all the other gauges. Im a little worried about the temp of my tranny. It Truck right now is in stock mode no dpf tune, crew cab srw with the 3:55 gears. Just driving normal around town I notice my temps stay in the 185 degree range and on the highway a little less. For example on my 35 minute commute to work this morning from the time I left my house till the time I got to work mostly highway with the converter locked the temps got to about 172 as the highest as soon as I got off the highway and into traffic light driving I saw 184 degrees. Is there a problem or am I panicking? The truck drives fine and the stock dummy gauge stays still all the time. This is all with the truck empty no weight. Thanks for any help.

The tranny temps you listed are fine. Just keep it below 230 while towing, that's when you toast it.

You'd be surprised to see that your temps drop a little after a DPF delete. I think it has to do with the better transmission shifting, and less time with the torque converter unlocked. Also, the lower exhaust temp and no EGR mean that the engine runs cooler too.

A stock truck can run up to 230* on a regular basis. I rarely see 200* when towing with the Spartan 210 tune.

Thanks for the help guys Ive been watching closer now and the highest they go is about 185 other than that its always below that temp.

With dpf delete and idp tunes mine rarely gets over 170. Even pulling our 20,000lb hay trailers.

My truck is stock and my temps stay at 170 and when I tow uphill, they go up to 190 for a little while.

My temps stay around 170. No tunning.

I had a good after market gauge on my '99 7.3 with auto trans. Over the years I found that the tranny temp fluctuated depending on the driving conditions, ambient temperature, etc. While towing my 30 foot fifth wheel camper I found that the temps remained lower as long as I was moving and had good air flow (I also had an after market fluid cooler installed on the old truck which helped). The temps would rise considerably when operating in stop and go traffic or maneuvering the camper around in a campground. When the vehicle is moving at or near highway speeds, even on a long uphill pull, the tranny temps should remain near the normal range.

My '08 6.4 has a gauge in the dash but it's a typical Ford Idiot Gauge (just like the oil pressure gauge on my '99). I have just installed an after market transmission temperature gauge on this truck also. I'm anxious to see what readings I get on this one.
