transmission oil cooler bypass

[dustbowl]

has anyone bypassed the oil cooler in the bottom tank of the radiator. i know it was a common practice on some other models.

Common practice? What models? Don't ever recall hearing of anyone doing it.

What are you hoping to accomplish?

I thought the 100 series came with a real transmission cooler, not just the bottom tank of radiator.

Also thought this was the story with 80 series too.

FJ62 it is a common practice to add a transmission cooler because they definitely do NOT come with one, other than radiator tank.

^^^^^ Correct.

Also...important to remember that the integrated 'cooler' also helps warm the transmission fluid in cold weather conditions. That might not be a factor for some folks in some locations.

There are legitimate reasons for bypassing, but for most folks...it is better left as is.

I had to do this on my previous 4runners to avoid the milkshake. I was also curious how the transmission cooler on the 100 differs.

mostly on 4 runners for the milkshake problem. also in a few 100's but not as common

Yes the 100 has both if it has an automatic transmission.

would you expound on the differences if any the bypass made on the operation or reliability of your four runners? did you install a bigger air to air oil cooler or just use the stock one alone?

Radiator failure causing transmission fluid/coolant mix seems to be a 4runner/Tacoma issue. An easy mod was to put in an dedicated transmission cooler.

Thanks for the pics. did the four runner have an oil cooler in front of the radiator before you added the one in the photo's?

Nope just was routed through the bottom portion of the radiator.
