Hello again,

so I’ve installed the CSF 3328 in my armada and I love it for engine temps. I just got back from a trip to the mountains with my camper in 90+ degree heat while having times of steep (7-8%) and very slow traffic.

My problem lies in the transmission cooling performance. I had this behavior when I bypassed my stock radiator but did not expect it on this unit.

For those of you who have installed the CSF radiator and tow with it, do you have occasions where the transmission runs on the hot side?

if this unit runs hot under load normally but never really goes too hot, I’d like to mount an external fan in front of it and map it to either a button or maybe the tow/haul mode button or a relay that would engage at a certain tranny temp.

Has anyone done that?
