Transmission Cooler

Well, I am considering adding a Transmission cooler. So I was wondering what brand have others used and has it helped. I have seen two that I might be interested in and thats the B&M Supercooler and the Hayden Transaver. Has anyone used these or is there a better one out there. I would like to protect the transmission the best way I can.

I installed the B&N and it makes a big difference. Well worth the $50. installation was easy. Just have to cut your transmission out line from the radiator in half . Install the unit vertical and have the fluid in line on the bottom so pressure and not gravity will force the fluid into the cooler.

I don't have one on my jeep, but I've wheeled with guys that do. The say it is well worth the $$ spent. My hubby has one that came stock on his commander, and he notices the advantage on the trails. I think moderator Barrie in Utah has a trans cooler, if you have any questions you could PM him.

I installed the B&M Supercooler. It has a capillary bypass so it only cools when needed. This avoids overcooling in cold climates. I'm not sure if the other units are designed this way.

I installed a Derale that is rated for 15,000 GVW on mine. Kind of overkill but it gets hot here in the summer.

Heh Heh, as usual I go a little overboard, I've got two coolers one "race" frame Mt. and one 18,000GVW cooler (rad Mt.)-

My coolers cool the tranny fluid an avg of 30 degrees, before it goes back to the tranny and never gets over 180 deg F-

I don't get that... A radiator is opposite, so that convection allows for better cooling (hot goes up, cold goes down, pull from the bottom and you get cooler coolant.). Is gravity an issue with tranny fluid circulation? A tranny cooler is on my list.

feeding the tranny "outgoing HOT" fluid, into the bottom of the aux cooler (out top) keeps and maintains the fluid in the cooling tubes the longest time, because of tranny pump pressure and this eliminates any "dead" air spots that could be present if the fluid depended on gravity for flow !!

Also keeps the aux cooler tubes as full as possible, after shutdown !

I've tried it both ways and the bottom feed maintains the "coolest" temps !

Same sorta deal as a fuel pump then? Tranny pump does "push" better than "pull"? That makes a lot more sense then Glad I saw this, I'd have mounted it the other way round.

The Hayden Transaver is 26,000 GVW. I was looking at it and it is quite large at 15 1/2 by 10 3/4" (B&M is 11 1/2 X 6 1/2"). Seeing that many thought a 15,000 GVW was large, I guess the Transaver one would be a real overkill. I wonder if the large surface area would effect radiator cooling?

Heh, everything we put in front of the radiator will affect the cooling ability of it, but.

We (auto's) already have the A/C condenser in front and without LAB tests-can't tell how much it will affect engine cooling--my aux cooler (#1) is a little larger (18,000 GVW) and it hasn't affected the engine (), so you might as well go forit

However, I have the stock cooler (Condenser bottom) completely outta the loop and I wouldn't recommend it for other installs--VOID WARRANTY--

Good luck

JIMBO

If you install the cooler with the inline on the bottom the pressure of the oil and not gravity will force the oil threw the cooler . The oil will stay in the cooler longer giving you cooler oil. The instruction tell you to install it this way.

I had one installed at Uhall for under 150.00. The dealer wanted 700 dollars.
