My Jeep can display the trans temp on the dash. The key to keeping a trans cool when towing to to keep the torque converter locked up. When unlocked it looses efficiency and the loss is turned in to heat. By dropping a gear when needful I keep my TC locked up and the trans temp stays down even in the hills of North Carolina.


Now the Nissan XTRONIC CVT has a torque converter and is designed to lock up when not needed. What I could not find was the criteria to unlock it.


CVTs have been in cars since the 1962 DAF Daffodil and have been greatly improved since but still are limited in peak power. A 3.5 liter engine is about the max.


So it can work very well if the logic is to lower the pully ratio when more power is needed and not to unlock the torque converter. I just do not know which it is.
