Re: Cooler install
If I was doing the install, I would leave the line from the transmission to the radiator as it is.
I would connect the radiator outlet line to an oil thermostat so it would route the fluid back to the transmission without going thru the 6.0 cooler or thru the 6.0 cooler and then back to the transmission based on fluid temperature.
If only those who knew what they were talking about replied, this thread would still be on page one.
