Prado auto transmission coolers

What is the feeling . Does a 2021 Prado 150 series towing an off road van 2.5.t need a cooler

What I am offering is an opinion, [not actual experience] based upon a fair bit of research for maintaining/servicing automatic transmissions. What you have briefly indicated is extreme driving conditions for the auto transmission. Towing heavy loads qualifies as extreme driving conditions. Normal driving condition is cruising down the highway at the speed limits.

Higher temperatures shorten the lifespan of the automatic transmission fluid. Being able to maintain a cooler temperature will ensure that the ATF will last and continue to provide the necessary lubrication and protection for your transmission.

My advice/recommendation is to have the largest transmission cooler suitable for your intended driving conditions professionally fitted.
