Transmission overheating

[Fornula Russell Champion]

Cheval Bleu engine and transmission…before fix.

On a 2024 Dark Horse Mustang, the catalytic converters, like most catalytic converters on modern vehicles, operate at very high temperatures during normal functioning.

Normal Operating Temperature:

• Typically, catalytic converters run at temperatures between 1200 and 1600 degrees Fahrenheit.
• Under normal conditions, you might see internal temperatures around 750 to 1150 degrees Fahrenheit (400 to 600 degrees Celsius).

Higher Temperature Ranges:

• During heavy engine loads, the temperature can increase, potentially reaching 1200 degrees Fahrenheit.
• In some cases, especially on the highway, temperatures of 1100 to 1400 degrees Fahrenheit have been observed.
• An inferred temperature of 1680 degrees Fahrenheit at wide open throttle (WOT) has been logged in a modified Mustang.
• Some sources suggest that the stock tune on a Mustang kicks in CAT overtemp at 1650 degrees Fahrenheit.

Overheating and Potential Issues:

• If the catalytic converter experiences excessive heat, such as from engine misfires, it can exceed 2000 degrees Fahrenheit and potentially melt the internal substrate.
• Unburned fuel entering the catalytic converter due to issues like misfires can cause it to glow cherry red and wear out prematurely.

In summary, the catalytic converters on a 2024 Mustang Dark Horse get extremely hot during normal operation to perform their function of reducing emissions. However, excessive heat can indicate a problem and should be addressed promptly.

The title of this thread is about transmissions overheating, but you posted an essay in catalytic converters...I'm confused

Are you actually having a problem, or just questioning Ford's engineering?

@Fornula Russell Champion ..... are you implying that the proximity of the overheated cats is causing the transmission to overheat? Like @AZ_Ryan I don't get your point.

If it was a warranty issue, the car would be at a dealership, which it clearly is not.

Looks like an AI post again.

Hi Ryan-

yes we have an issue with the transmission over heating at Sears Point under below average temperatures. (55 degrees to 65° ambient air temperature…

from cold pits the transmission is overheating within 13 minutes while short shifts stay under 6,000rpm & shifts between 5-7gears.

Hello all- yea AI helped out by pulling all possible info available on the web…truth be told my mechanic Tony aka(Fix It Again Tony) pointed it out to me as the engine had to come out to replace the right front clip since I hooked it into the tire barrier on the outside of Turn 1 when I pointed a faster big winged car by on my inside and lost all the air on my car and lost the downforce @ 123mph.

we are adding a large 20” x 14” x 6.5” fanned cooler(thx Jegs) in front of the radiator to cool the transmission. Then on top of that we are going to delete the cats(thx Team Beefcake) for good measure.
