Transmission cooler - Page 2

well, i got the cooler in on thursday, put it on friday. it took me so long to decide where to put it, finally i decide to go with a more stealthy location between the ac condensor and the radiator. fits VERY nicely in there.

when i first started hooking it up i made a HUGE mistake and hooked it up to the power steering. on the diagrams on subaruparts it looked like that was the right one, but it wasnt obviously. if the p/s didnt use tranny fluid i would have caught it, but since its the same i didnt think twice. finally i got it hooked up right, and everything went smooth until yesterday. i drove my family into town and i was squirting trans fluid EVERYWHERE!!! i was so mad, i knew it was coming from the front, so it was the actual trans. i took everything apart again and just tightened everything up. the problem is now solved!

after an oil change today, and new brake pads tomorrow, ill only have a couple more things on my to-do list!!

I had a similar thing happen when I put in a remote tranny 50k filter. Started it up no leaks, but after 5 min of driving there was a trail behind me. The problem was I didn't have the hose on the whole way.

yeah, that might have been part of my problem too because when i fixed it the tubes slid on further (from being warmer and stretching) and after that and tightening them down more im not having any leaks.

Well, Planet earth, AFAIK.. read this, about the B&M cooler you are recommending. This technology of orifice vs. viscosity is not new...

This is a brand new in the box B&M #70268 Automatic Transmission Fluid Cooler.

B32-70268

B&M SuperCoolers are 100% aluminum construction and use stamped plates sandwiched together to create one of the most efficient oil cooling devices available. Not only does this unique design provide for maximized cooling through more efficient heat dissipation but it also provides a much sturdier cooler which is practically impervious to flying rocks or other debris. The Super-Coolers intended for automatic transmission fluid also offer an additional feature known as Low Pressure Drop (LPD). The coolers assembled with hose barb ends include a unique bypass feature allowing a controlled amount of ATF to bypass the stacked plate core when the fluid is cold. This is beneficial in cold climate areas to guard against lube system failure. Controlled by viscosity, fluid is returned directly to the lube circuit through bypass openings in the stacked plate core. As the temperature increases, more ATF is directed through the core. This highly efficient design combines improved protection against lube system failure with the required levels of optimal heat transfer.

the smallest size & lightest weight cooler relative to cooling capacity you can buy.
Better cooling than ordinary fin & tube coolers.
Rigid stacked plate design resistant to damage from flying rocks or other debris.
Pressure tested to 200 PSI.
Low Pressure Drop (LPD) feature included on #70255, #70264 and #70268
Includes installation kit.
70268 - SuperCooler rated at 13,000 BTU 11"x7-1/2"x3/4"

That's totally correct Gordon. I'm not sure why Your Confused is confused.

There is no need for an electrically operated thermostat with this type. It uses a type of thermostatic action that is activated by viscosity. Put simply, when the oil is thick it goes back to the tranny. When it has heated up enough it fills the cooling passages and gets cooled.

What is so hard to understand about that?

Oh, and just on one point. I don't know the actual model number, but Jegs' site will show it. You should be using the 19,000 lbs model, because it is larger and cools better. Particularly in places like Texas. This is the largest B&M model that will fit between the two rads in our cars, check the available depth.

I can't believe you just said that Gordon. Engineers, huh?

My dad's 3600 GVW in the '97 is also an LPD design I think. I will leave the details up to him, but here's a picture.

On that B&M trans cooler. hows does that installation process work like do you have to the mess with the stock trans filter thats on the car. My tranny is rebuilt and i gotta get a cooler on it so i can do road trips

Be careful about the cooler. Blow through it and see if it feels like you are blowing through a restriction. If it is, you're going to cause problems. Cooler circuit restriction is the real problem, with these transmissions, not heat. Also, be careful of thermostats. One should not be necessary unless you have a way oversized cooler. Keep in mind the trans isn't considered warmed up until 176f. You also want to keep the circuit as simple as possible to avoid restrictions. A filter is not necessary unless you have a 92 or 93 model with the old converter still installed. I had a cooler very similar to this on my car and it was a huge restriction and was a contributing factor to the demise of my trans.

See mine, search "the ultimate transmission cooler"

It still has the external filter

jjanak79 · #26 09-22-2009, 01:36 PM

Also is there like another cooler. one in front of the radiator whats that for?? i see a line to the powersteering fluid and one that goes to the back of the engine.

redlightningsvx · #27 09-22-2009, 03:51 PM

That's the power steering cooler.

jjanak79 · #28 09-22-2009, 04:46 PM

So where would you put the trans cooler in between them? or what

jjanak79 · #29 09-23-2009, 11:12 AM

isnt the idea that its supposed to the front to catch the air?

The bit in RED wasn't info listed on Jegs web page and was the reason I had no idea what you were referring to. I read your post several times trying to figure out what you were talking about and finally figured that one of us was off our rocker. lol

Still at a rating of 19,000 GVW and in a position behind the condenser and in front of the rad. I think this cooler could use a bit of help during the summer and a bit more bypass during the colder months as it takes quite a bit for the trans to reach operating temp when it is cold outside. (you know 4th gear and locked)

Thanks for the bit of info this has provided. It's always nice to learn something.
