<div class='quotetop'>QUOTE(Red03SilSS @ Sep 27 2006, 02:41 PM) [snapback]66823[/snapback]</div>Interesting... My Yukon came with the 5.3, which has the lines running to the auxilary cooler, to the 28" radiator, then back to the trans. I have a buddy who has an '00 Silvy (RCSB) Z71 that has the same setup (stock). Could it just be different with the LQ4s? I've always been told to run an aftermarket cooler for trans fluid. I will say that the fluid gets pretty hot under load.1. Most 6.0L have oil coolers built into the radiators, which most 5.3L and 4.8L have oil cooler block off plates. You could take the blockoff plate off your 4.8 and put it on the new 6.0.[/b]
