So I was on a week long offroading trip here in Utah and some in Wyoming a little bit ago.
Overall my FJ62 did phenomenally, especially since it was a 100F plus every day.
The AT did struggle here and there with the heat and it needs some attention before my next trip.
A few facts:
- I have been running a trans cooler for years, but just one of those smaller 10x10 Hayden ones., in line with the OEM radiator cooler. My radiator is only a few months old.
- I had fresh Amsoil synthetic ATF in there.
- I had my AT light come on, on a long on road mountain pass climb. When I stopped to IR check the temp on the pan ( around 300) I noticed it wasn't circulating properly through the aux trans cooler...The temp on the cooler was around 125, even felt cool to the touch. I took the hose of the cooler IN fitting real quick and flow was low... at idle however.
It's having some flow issues I think, the aux cooler isn't plugged or anything, so I'm removing the pan to check out the filter, magnets etc. and do a flow test.
My AT operates perfectly otherwise.
I'll Rodney flush with a few gallons of fresh Alyssin Transynq after cleaning and checking everything.
But I'd also like to install a better / Larger cooler...
2 Questions:
1: I've narrowed my search down to the below coolers. Keeping price out of the equation, which one would you choose and why? I'm leaning to the Derale stacked plate. They're all very roughly the same size in square inches. The Derale stacked plate is about 2 inches thick though.
Does the Tube & Fin drop the pressure by a lot?
2: Wouldn't it make more sense with a larger plate cooler, to mount it with the IN/OUT fitting at the TOP, not the bottom? So that the whole cooler can fill up before it overflows to the OUT? I notice many people mount them with the fittings facing down. My factory 100 series cooler starts at the top and drains at the bottom, which seems more logical.
I'm taking another week long trip in 2 weeks time, so I'm trying to get the AT back in tip-top shape!
