Mishimoto MMOC-F Transmission Cooler

[LCnAZ]

I can't find where anybody has tried this cooler. Given the Arizona climate, I'm thinking that a fan cooler is a good way to go.

Anybody tried this one? Thoughts?

Behind that fan is a regular ole tube fin cooler. They're not as efficient as a stacked plate cooler. If you got a nice stacked plate cooler, you wouldn't need that fan.
A fan would need to be thermostatically controlled. Otherwise it would cool it too much.

I agree with using a stacked plate and not adding anything electrical to the truck.

Thanks guys. I see that the B&M 70268 is the stacked plate type.

@LCnAZ I bought the BM 70268 for $85 with Amazon Prime .

Installing it this weekend .

Go for it!

 

[LCnAZ]

@hygge Woo hoo! Let us know how it goes.

This weekend is drain, inspect, clean filter, replace gasket, then the Rodney
Flush, changing to synthetic. After I drive a bit to evaluate the post-flush/change performance, I plan to go with the B&M 70268. I will have a tight fit beside the 12" condenser fan I installed on the passenger side of the condenser, but I think it's going to snug in there in a vertical orientation...which also puts the input and output on the driver side.

@BlackCat is going to join this discussion. He has a fan-driven model and would like to add his two bits worth.

Haha, here’s my two cents. Keep in mind I’m in AZ and I needed to keep the trans cool when it was 118 out. I had a 70268 on my old 4Runner and it worked well. So I put one on my 62. With it inline with the factory cooler, I routinely saw trans temps around town of 260+. The temp sensor was on the outflow trans line going to the radiator. Pan temps were 220-230ish. So I installed the Derale tube fin style with fan. The fan was wired in to the rear heater switch so I could turn it off going thru rivers and such. After installing it, my temps dropped by 30+ degrees, and I generally saw pan temps of no higher than 190 using an infrared heat gun.

I like the temp sensor on the outflow line for one reason- I like to know how hot the converter is getting. Using the infrared heat gun on the pan to know that the trans had a steady supply of much cooler useable fluid was a bonus. So in my case, the “lousy tube fin style” cooler and fan was a drastic improvement over the 70268.

Thank you for your input. I welcome comments from others.

I think I have a slam dunk solution that covers all bases. I'll install the B&M 70268...and install an 8" fan on it. I've got the room physically and electrically.

Thanks, senior. Educate me on that in-line filter.

@LCnAZ in-line magnafilter has a magnet in it. As your transmission ages and there are micro-metal fragments in the ATF it helps to keep the transmission run longer .

I figure at 250k miles it can't hurt from a preventative point of view .

I installed the B&M 70297 with a fan behind the grill....
I have it wired with a manual switch....
This past year I swith to -6AN fittings on all the tranny lines...

EDIT: Yikes !!! just notice the price on these...
I paid 180.00 back in 2010...

You bet. Thank you.

I used a plate style Derale Atomic cooler from Summit Racing with a fan and 180 degree thermostat. Seems to work well. I never monitored temps prior to it's installation so unfortunately I don't have before and after numbers but it does keep things under control when pushing my heavy '62 as hard as it will go.
