Curious to know what transmission temps you folks are seeing. I was shocked to see 217 deg. on my 7.3 with 200 miles no extra weight and 39 deg outside air temp compared to my 6.0 diesel with torqshift runs in the 160 deg range.
Lot of talk about this on another forum. Apparently Ford has found that the transmissions operate better at higher temps and anything under 230 is supposedly ok. I'm used to seeing 190 during the summer and maybe 208-ish when towing in hot weather on previous trucks.
I see 218 regularly on my 2020 while unloaded just driving around and it's been winter.
According to the trans failure chart you can expect 80,00 miles if you average 200 deg and 40,000 at 225 deg not sure if that is considering synthetic oils.
