Came across this looking for some pointers on towing, and it seems like the general consensus is an external transmission cooler and something to monitor the transmission temps. The previous owner cooked the transmission and replaced it with a reman unit purchased from toyota along with the radiator and all the lines hooked up to the transmission. Everything has less than 5k on it without any towing miles, so I'm looking to make this last as long as possible. These trucks, without the external coolers seem to run really hot, even without towing.
I'll be towing my track car with this setup. 2200lb uhaul trailer, 2000lb car, maybe another 100lb of extra wheels and tires with it all. I have the factory rear air suspension and am wondering if it'll hold up to all this, especially with how the uhaul trailers position a lot of weight at the front.
I'm set on installing an external oil cooler for the car and am between a couple options. The two main installs I'm seeing are the OE oil cooler and the hayden one. The OEM cooler is very pricy with all the parts, but It doesn't' seem to route any differently than the universal kits through from what I'm seeing. Part number 9 in the diagram seems to be a hardline that is more or less used in the same-ish manner as a sandwich plate in an oil cooler and routes the lines away and back to rad outlet, right?
The OE oil cooler also seems a bit small compared to some of the other ones I've been seeing. Is there something I might be missing with the OEM oil cooler setup?
A lot of people seem to be using the Hayden cooler which I bought for an LS430 that I owned, but wasn't too happy with the build quality. Leaning towards buying a Setrab cooler and using some of the fittings that are lying around. With the routing of an aftermarket cooler, does anyone here bypass the integrated cooler in the rad or install an inline filter? Also wondering how sensitive the system is to pressure drop. Does the cooler pump back into the pan? Or does it directly feed into the transmission or TC?
Setrab seems to have a multi-pass 11in x 6in cooler that looks very promising. Might be able to throw it in without having to relocate the horns.
With installing an aftermarket cooler, is there anything specific to this chassis that I have to look for when choosing a cooler and routing it? Very new to working on trucks and the whole automatic transmission thing.
