Mustang 2024 GT/CS
Hi everyone,

A week ago, I bought a 2024 Mustang GT/CS with the 401A equipment package. It's an automatic transmission.

During normal city driving, my transmission oil temperature runs between 239°F and 249°F. The ambient temperature where I live ranges from 90°F to 104°F. Meanwhile, my cylinder head temperature, engine oil temperature, and engine oil pressure are all within normal operating ranges.

The car has 15,000 miles on it, and I just had the transmission fluid checked today—both the fluid level and its condition are perfectly fine.

What could be the issue here? Has anyone else experienced this problem before?

This is not "spirited" driving, but just commuting?

The CS has an optional performance package which would have an auxiliary transmission cooler. Does your car have the optional performance package?

I live in Phoenix and Ive never had that problem. Are you using paddles or aggressive driving?
