TRANSMISSION COOLER INSTALL
So I took the 4runner on a 8-hour trip to go skiing with my family and 7 hours into it, the transmission decided to start overheating frequently. So that led to me getting a Hayden 679 transmission cooler to install. Went pretty smoothly, and the trans temp has definitely improved a ton. Very useful mod.

Installed:

Top of cooler connects to radiator:


Bottom of cooler connects to hose from transmission:


I didn't regear when I got 35s so that's most likely why I was having overheating issues. Would highly recommend this mod to anyone
