Tomorrow, I will install a transmission cooler (Hayden Trans-Saver) in my Grand Cherokee (4.0L engine). Is there anything I should watch out during the installation process? Any experience? Suggestions?

Is it necessary for me to remove the front grille prior to the installation of cooler?

Thanks!

I have not added a tranny cooler myself, but two things come to mind: first removing the grill will be advantageous. Second you must id which ATF radiator line is the return line back to the tranny, for this outlet line should be connected to the inlet of the cooler. Otherwise you would cool the ATF and then send it to a hot radiator, which you do not want to do. If someone can confirm my logic it would be nice, as I have no experience in this.
