Best tranny cooler to bypass stock radiator?

[49Runner]

Just picked up the BM cooler on Amazon... $49.00. Cheapest price I've found.

I live in Alaska and my focus is to prevent the milkshake but keeping the tranny fluid warm enough is definitely a concern.

I'll be playing with mounting location this week. I'll post pics for my cold weather brothers and sisters by this weekend.

Hi guys
About trans coolers installing bypass stock radiator
The most important is to experience the two ways of installation
If you live in a warm climate 25-35 DEGREES CELCIUS ALL YEAR LONG you must forget the stock radiator let me repeat it again FORGET THE STOCK RADIATOR
Do not add heat passing tru the engine radiator before you try to cool down your fluid in your trans cooler.
Install the larger trans cooler or 2 medium size trans cooler in order to have a maximum surface in front of your ac condenser or radiator
This surface must be at less half of your engine radiator
You really will have a cool temp fluid even in hot season in stop and go traffic
In extrem hot temp climate (36°C) 55mn in stop and go traffic with A/C in max position my trans temp gauge never exceed 185°F and cool down in 5mn driving at 45MPH to a stabilized 175°F
Engine temp was +-200°F
My car : 97 jeep grand cherokee 4.0L // 2 medium hayden tube and fin cooler bypassed installed IN FRONT OF THE CAR
I did install the 2 trans coolers + a trans temp gauge 3 years ago and no more temp problems
Smooth cool and safe driving everydays because the atf keeps his colour and function longer at cool operation
Do not believe anybody except your trans temp gauge BECAUSE IT NEVER LIES
