FZJ80 transmission cooler (worth keeping?)

[NatualLivingMaine]

Is there any value to keeping my factory transmission cooler around? I'm upgrading to a 24 row Setrab unit.

Some of the front fins are soft, the rear fins seem fine.

Toss it, plenty of aftermarket ones available

I just didn't want to toss something someone would need/want, it serves no use for me

Thanks for sharing this. Which Setrab are you installing? Does it bolt in without much trouble?

I’ve used one in the past as a power steering cooler. Someone might want it.

Setrab Series 6 PN 23-6002 34 row cooler. It's certainly not "bolt in" but I'll post up pictures once I install everything

Why? That's vrtually the exact same dimensions as the OEM cooler.

OEM cooler is only 17 rows.... size doesn't = cooling

The 34 row is literally twice the cooling surface

You don’t need a cooler with twice the surface area. I’ve ran a temp gauge for years and it usually indicates 140-150 unless conditions became extreme. I once saw 175 while experimenting with rock crawling in 90 degree heat with the AC on. Lots of TC slip and low air flow going on in that scenario. Are you installing this cooler because you eliminated the fluid to water portion of the cooling system or is it because you know better than the engineers? If you have figured something out that the rest of us have missed all these years please share that information.

I'm installing this cooler because Toyota discontinued the factory cooler I don't trust.

Here are the factory radiator and AC condensers I am also replacing...

Can you post a pic of the new trans cooler? I have a Derale stacked plate and fin cooler on a shelf waiting to go into my new build. It’s 2” thick, 19 rows and 10” between ports. I’m no engineer but it seems comparable to the stock cooler.

I looked up the part number you posted but their site lists all series 6 coolers with PN’s beginning with 50-xxxx.

Setrab Series 6 Oil Cooler, 34 Row, M22 Ports - Pegasus Auto Racing Supplies

The Setrab Series 6 Oil Cooler has a brazed aluminum construction which provides the maximum cooling capacity in the smallest possible space, with minimal pressure drop.

It's on its way so no physical picture but dimensionally they're the same. The Setrab just has twice the passes. I've used Setrab in the past on multiple race cars and trust their quality.

That’s a lot of cooler, almost twice the area of my Derale 13403 which is rated at 37,000 btu’s and up to 26,500 gvwr. You might run too cool during winter up north.

That's a great point, but I already have a solution.

I like the 30 row aftermarket coolers. Fits perfectly

I went searching after I posted my question and did see that exact ad on eBay. Seems like over kill. I have on the shelf waiting to go in a 19 row by 2” thick stacked plate cooler. How thick is the oem cooler? Much closer to 1”. I tossed the two I had so don’t have one to measure thickness off. The 19 row should add cooling capacity over the oem unit. 30 rows is about double the capacity. The OP knows this and plans to use a thermostatic valve to keep the trans from running too cool. I ran hard in high temps with the oem cooler for ten years and never saw 200deg and during 30-40 degree winter days 140 always. The thermostat adds complexity that I don’t want to have to deal with. A buddy of mine runs the same 19 row cooler I have on the shelf and his temps range from 160-200 living in So. Cal. Seems about right.

Progress has been made on the coolers.

A/C has been deleted, it hasn't worked in years and sourcing hard lines in northern Maine has been impossible.
