Transmission Coolers

What are your thoughts on transmission coolers?

Hey Scotty, love the channel. I have a 2015 Nissan Sentra and I was wondering would a transmission cooler help with the CVT since they are known to go out prematurely.

well, yes and no. realize trannys are designed by engineers to run a certain way, and believe it or not, sometimes running too cold harms them too

A cooler can help tranny reach normal operating temp sooner but yes it must have been designed this way for a reason.

yes it will help if u live in arizona 100F in the summer
