god almighty, why do I keep clicking on this link.....

Shame on me

Agree that the transmission may be the weak link that sets into limp mode, just don't think anything from the engine with respect to oil and coolant temps would be the trigger of limp mode on a high speed run. That said, it is not surprising to me that high speed runs on the autobahn doesn't result in limp mode given the many experiences of other high revving engines on the autobahn. When the engine (operating at closer to peak TQ on downshifts, which is peak load/piston pressure), diff and transmission are working hard in a track situation (where there is much more friction) and where you tend to be in a lower gear, makes sense that engine and transmission temps would be higher in such a situation regardless of actual speed.

I agree that maintaining temperatures with external air-liquid heat exchangers is feasible at high speed. That's what they are designed to do.

In this instance, we are talking about a non-externally cooled transmission. At 150MPH, the heat source within the transmission (friction/drivetrain loss) is much higher than that of normal highway driving, due to the increased loads. Additionally, the local components that radiate heat into the trans (cats and exhaust) are operating at significantly higher temperatures than normal, thus radiating more. We've all seen videos of exhausts glowing red under high loads. Granted, there is additional air flow over the trans at high speeds, the question is whether that increase in flow can compensate for the increased power being generated both internally and through radiation (and convection from the exhaust). My opinion, based on the amount of trans surface area actually exposed to the air stream under the car would be no, not for an extended period of time. After some unknown period of time at 150mph, the un-cooled trans will most likely overheat.

The fact that, in this instance, the trans did not overheat during this run adds to my skepticism that un-cooled transmissions are overheating in traffic, a significantly more benign environment.

Are you running B roads in the winter on stock tires? No issues?

I got a great deal on winters. The only issue os that the rears werent as wide as the summers that came off.

I drove up a hill in a flash snow storm that others were getting stuck on. So the tires are good.

Can some Me point me in the direction on how to activate the trans temp gauge ?

I searched and it only showed this thread and a differential cooler thread.

Omg. This thread is some seriously low end clickbait! I avoided but made the mistake of looking at 13 pages lol

Let’s sue Ford because we can’t read a brochure. In 13 pages only a few like Harold alluded to the reality: only an attorney wins. The rest of us enthusiasts lose and should be pissed. Total disaster and embarrassing that this is the most active recent thread.

You can make it less pages by going to your settings and changing posts per page. Then it would be only 5 pages you wasted your time on.

Thanks! Learn something new everyday! There are several nuggets in those settings.

Carry on ...

[MENTION=19066]Epiphany[/MENTION], how much time have you spent in a Tech pack w the trans temp gauge enabled but without a trans cooler installed? Have you been able to study the real life conditions leading to high trans temps?

About as much time as most Tech Pack owners have bolting on coolers.

The answer to your second question is yes.

So yes temps continue to climb after the high speed run

This is why you would do a cool down lap at the track. Same goes for what you did.

VERY important. Or opening the hood and letting the car circulate fluids for a moment after an autocross run on a 100 degree day. Autocross is fun...low speed but high work on the components. :doh:

My experience:
Activated Trans Temp Gauge at 300 miles, street driving only up to 9,500 miles when I installed my cooler. Max temp on a 98 deg day in summer with an hour of driving was 205, this was after an hour of mixed stop and go and aggressive driving (won't mention speeds on the country backroad here). In my experience not enough to hit limp mode, imagine it would take hours of driving. I will say that it will keep slowly climbing. The only way to get it to decline is to turn the car off. I don't really need a cooler, but wanted it just in case. Now I turn it on at about 165 and then off a few minutes later at 140. Activated my rear diff gauge about 500 miles ago, max temp so far is 157, 88 degree day one hour of driving.

I have trans temp on display since almost new. On many different spirited, high rpm driving sessions chasing several other GT350s that are either Track Paks or newer models, my temps usually hover around 225. The other 350's never get hotter than 145 to 150. Yesterday I was chasing a Viper, Lambo, and a new R and my temp hit 250 and stayed there a while. No limp, but damn that's hot. I run the BG Synchro shift fluid.

Great example!

On the west coast, we are blessed with many tracks and those different tracks present very different temperature conditions where you can observe data. One track is Thunderhill raceway, where in a 5 mile configuration includes a 3 mile part with longer straits/sweepers that is high speed and a 2-mile more technical auto-cross portion. Guess after what portion the of oil/coolant/transmission/diff temps are the highest? It’s after the auto-x part which is much lower speed. Once you get onto the higher speed 3 mile part, these temps go down modestly then go back up again once you hit the 2 mile auto x part. This real world experience (observed both in the M3 and GT350) completely makes sense: in the low speed auto-x part, you are working the diff through the turns, you are operating closer to peak TQ being in lower part of power band, you are in a lower gear (greater TQ at wheels due to gear multiplication), there is lower airflow/heat exchange, the brakes are being worked and the tires are heating up more. Then you move onto the fast part, airflow increases, you aren’t shifting gears, there is less TQ to the wheels, the diff isn’t locking, the engine isn’t at peak cylinder pressure, brakes aren't being worked and you have much better airflow/heat exchange.

VERY important. Or opening the hood and letting the car circulate fluids for a moment after an autocross run on a 100 degree day. Autocross is fun...low speed but high work on the components. :doh:

I may be the minority but, I love my Tech pack car. I didn't get the track pack because I didn't fit in the recaros. Which is funny because the Boss seats fit just fine. Now, I have added the track pack Transmission and a rear end cooler because I want to track the car. I have no more into my car then a 17 with the tech option., I thought Ford was more then fair on the pricing for the trans for the tech pack owners. I did not get off as cheap as those who just added the pump but for the trans I have less then 2 G in the car.

You bought the transmission for less than 2k? Where?
