Towin' Tahoe
New Member
Towing my trailer for the first time in my '09 LTZ my transmission temp hit 213 on a long steep grade over the Siskyou Mts. Normal operating temp is listed, high end, at 200 degrees. How much wiggle room is there and at what point should I pull over and stop? Is there a good way to cool it down other than find a downhill grade? BTW, I am towing only 65% of capacity by weight.
