I pulled my 27ft TT with my 2011 f150 lariat screw this weekend and my trans temp got up around 220 while in a good pull. Is this normal? The TT weighs 5000lbs mty so with my gear it was probably around 5500 lbs or so. I have the 373 rears with the off road pkg and the 5.0 engine. Is this to much trailer for the truck because other than the trans temp it handled it ok.

 

Mine runs 220-220 while pulling mt 750# TT in the hills of east Tn. So appears to be normal.

 

Good because I was getting worried, and it was in a hard pull so I guess it isnt bad.

 

My 2010 doesn't have a gauge that tells me exact numbers. In fact, I don'tthink it is really hooked to anything as it never changes, no matter what I am doing or how hot it is. I think it is there to keep people from worrying about it.

I think 220 is way to hot for a trans. Needs a bigger cooler.

 

The tranny on the 2011 is designed to run that temp, from what I understand. Not like older style trans where temps in 150s was the norm

 

Agreed. Unloaded my tranny is running 192-202F, even sitting idle the cooling system will bring the tranny up to operating temperature.. (although it would take a while).

Towing a 6000# car trailer last month in the 105F heat my tranny was reading 197-212F. It was mainly freeway towing though, on the freeway it would settle around 197-201F. On the surface streets is when i was seeing the 212F numbers.

 

If the gauge is never changing, maybe the cooler is doing its job.

For 2010s with the message center, there's a way to put the instrument cluster in "Engineering Test Mode" that will give you a digital readout of the tranny temp. Just hold down the reset stalk when you start the vehicle until the message center displays "Engineering Test Mode". It usually displays this message when you've held the stalk down for five seconds after starting.

It stays in this mode until you shut off the vehicle and the truck operates normally other than displaying additional information. You have to do this each time you start the truck though. So far however, I haven't bother to check the tranny temps when towing and when not to compare them.

 

Thats about where mine runs. I have a 7200# TT fully loaded. Around town on a hot (90Degree+) day I have seen temps around 220. Unloaded on hot days I see around 190-200F. I have an edge tuner so I can see the temp all the time. I also have the factory trans temp needle. Even when the temp was at 220F it never indicated that it was even close to overheating. This makes me believe that the temps I am seeing are normal.

 

Yep. No reason to worry - totally normal. On the '11 model year, the indash LCD screen has a digital trans temp readout I can monitor it all the time as well
