i have a 2012 ram 1500, 5.7 hemi, 3.55 ratio, was wondering what the normal temp is for towing 6500lbs tt. what is hot temp, and what temp do i start getting concerned?
You have synthetic fluid and temps up to 240 are not exceptionally high. The trans will lock out OD in an effort to save itself when it gets to about 260~265. At that point the fluid is dying and has very few miles left in it.
