In the winter, with the inline trans cooler, my trans consistently runs at 120F and i haven't had any issues, at all. A cool trans is a happy trans. I bet a trans running cooler than "normal" will last longer than one that's running hotter than normal. AFAIK, high temp is the #1 killer of transmissions and I've never heard of transmissions issues because they ran too cool. But hey, what do I know...

I'm thinking you have a regular plastic tank Koyo. I'm speaking of the all aluminum they just released this year. Only downside is that they didn't include the trans cooler so bypass in mandatory.

Yeah, I honestly see no problem with the factory cooler when not towing. Agreed better cooler than hotter.

So I was in the same camp as you. My trans cooler actually came out of a 5.9 cummins from a junk yard ($18 if I remember correctly) and I ran just that cooler for close to 8+ years and never had a problem. it would sit at 140* in 85* ambient and spike to 160 if I got on it. Last winter I was driving through a -2*F section of road and my trans temp cooled off to 90*F after driving from Sacramento to Tahoe up hwy 80, it had 1.5hr to get to full operating temp.
That was too cold in my book. I installed that oil thermostat and its been great. Cruising on the hwy I sit at 159* as long as its not 100*+ outside then will spike to 185 if I jump on it to pass someone or climb a long grade with the torque converter unlocked. I did a quick cool down time using my scan gauge and a stopwatch in my head. The scan gauge will report 185* and cool back down to 165* is about 7s, having excess cooling is a great thing!
I doubt it was the only reason but noticed a pretty significant mpg gain but I do not know if that was related to something else, who knows.
I do agree with you, it is better to have a cold trans than hot, but I also think there is a better way to control the temperature rather just let it get as cold as possible.

I got an OEM one from my local toyota dealership for $200.

And where was it made? At $200, definitely not Japan. Like I said, legitimate OEM meaning exactly what it came from the factory with.

I found a link to this all aluminum 3 row radiator but they are always out of stock. Do you know of another place that has them in stock normally?
I'm thinking I may move the new Denso radiator I installed in the 01 to the 98 since it probably needs one anyway and get one of these 3 row aluminum ones for the 01 since it's my keeper.
Also; I wonder if this 88-95 2-row aluminum radiator could be retrofitted for the 3rd gen 4runners. The price is decent enough. The inlet and outlets are in the right spot but I don't know about the hose size and if the mounting holes line up. Any experts here know?
3rd gen Denso:

Call them. They probably need to special order it which is why they don't stock it.

Probably right. They are likely made to order so they don't have a bunch sitting around taking up space if they don't sell that many.

Well decided to buy local to verify condition and put an end to this returning madness. Went with one from Advance auto, Carquest brand, $107 with 25% coupon with tax. Looks exactly like every other radiator on the aftermarket. Trans fittings were tight, mounting holes and hangers lined up perfect, threads were clean, no broken nipple or damaged fins. Literally took 20 minutes to swap out.
Multiple extensions and wobblers make accessing the mounting holes through the grille and bumper a breeze.
We'll see how it holds up.
Prior to changing I a ran a bottle of Thermocure from Evaporust. Seemed to work really well.
Now, we're do I position the jiggler on the OEM thermostat?

Did you get the one with lifetime warranty? I just swapped one in to Advance for a free replacement. No questions asked.

I didn't even think to ask but I just checked online and it sure does fall under the limited lifetime warranty. That's great.

You'd have to ask Toyota, but it was OEM toyota. Came with the toyota part number sticker and everything on the box.

Jiggle valve goes at the 6 o'clock position per the factory service manual instructions.

You got the Taiwan one.
Lifetime warranty usually means you will spend a lifetime returning and replacing. They tend to last 4-5 years of normal driving in my experience.
