Tranny cooler

I'm told I better get one of these for my '05 Rubicon auto. It does seem to light up the floor board in the summer months. I'm interested in one I can slide through the headlight opening. I would like to keep it under 50 bucks but if there's not one out there any good for that, I will spend more. Brand and model please, I want to order one soon!! Thanks!

While an auxilliary transmission cooler is an excellent upgrade for any automatic transmission, the heat you're feeling under the floorboard is actually from the catalytic converter which gets REALLY hot.

This type of cooler fits through the headlight opening.... I first installed one for my transmission in my previous TJ and installed the same type of cooler for my power steering system in my present TJ. PM JF member mrblaine who sells them with a cool mounting bracket that makes installing them easy.

In that price range, B&M has some passive coolers that work well mounted in the grill.

Yep. I've been running one of these for the past few years...

My 3-speed runs nice and cool (trans temp gauge), even towing a small fishing boat.

I have a small B&M with a remote filter and deep pan. I need to install a temp gauge but so far it works great.

You mean the B & M cooler I posted? No, but it's pretty thin. You can slip it behind the grill after loosening the radiator. The rad hoses remain in place, no mess.

You can clamp it to the diagonal grill supports with insulated cable clamps, available at Lowe's, McMaster, etc.



Mount the cooler with its hose fittings pointing up.

Actually I have put that cooler in through the headlight hole. It requires cutting two small notches in the grill around the light and then "encouraging" it. Once everything back together the light bezel covers the notches.

cool. I pulled the grill last year to have it re-painted.
Those weird rubber insulated fasteners holding the rad on were a PITA!!!
had to replace them. Unless I need a rad it aint coming off again if i can help it.

I have the inline style like jerry showed on my buggy from the aw4 swap.
It seems to work good. The one I bought is huge, and way overkill.
Its mounted in the wheel well area. Its almost as long as my hood front to back.
with no fenders it gets tons of airflow. Smaller would b better on the rubicon!

Is there an opinion on what style is more efficient? I would assume the flat style is with good airflow,
But thats just a guess.

Don't forget to install a quality external transmission filter. Cool and Clean ATF is the key to a happy long living transmission.

Here's a picture of another possibility. A hanger like this will allow mounting of two B&M supercoolers side-by-side.

Sorry the picture is of a closeout, but it should be possible to find something like this out there, because a shop installed a dual-cooler set-up for me about six months ago.

My dual-cooler set-up on the hanger might have been a bit more labor-intensive, though, than was described above.
