350 vs 400h towing questions
#16
This is why towing is ALWAYS supposed to be done with overdrive OFF. With OD on, the torque converter will frequently unlock, which causes the temperature in the transmission to increase and will eventually cause transmission failure. Towing in 4th allows the TC to stay locked for significantly longer stretches, lengthening the life of your tranny.
The 1mpg you save by towing in 5th gear isn't worth the $4,000 bill you'll get down the road...

But I believe you, you do not want to tow in 5th gear position allowed!

The 6 speed in the 2010 RX actually has two overdrive gears, 5th at 0.71:1 and 6th at 0.61:1. So you'd want to restrict that one to 1-4 for towing as well.

Does anyone have pictures showing the tow prep package transmission cooler? I am buying a 2008 RX400h and haven't been able to find any way to confirm it has this. There's a cooler in front of the ac condenser but i've seen people say it's in the lower corner of the bumper.
Please help!
