Every truck I have ever owned in the past had a section on Towing in the owners manual. In that section, every one said that when towing, lock out the torque converter, i.e. do not let the vehicle use overdrive.

I can not find anywhere in the FJ manual that addresses this issue. Recently I towed a 2500 pound boat from Atlanta to Florida. During that trip, I kept the tranny locked so that it could not use 5th gear (this is an automatic we are talking about).

I want to know if this is the right thing to do or not??

Does anyone know? Toyota will not say.
