Cyclozene Posted March 1, 2012 Share Posted March 1, 2012 I had just finished my sti swap and was putting everything back together. Long story short one of the plastic nipples decided to break. I ordered a MT radiator. I have the medium sized hayden transcooler now. Will that be enough to cooler the atf or should I look at a bigger one or even two transcooler to do the job?

Max Capacity Posted March 1, 2012 Share Posted March 1, 2012 Judging by where you live, I think you'll need more cooling.

AZP Installs Posted March 1, 2012 Share Posted March 1, 2012 Normally i would say it would be enough, but as max said, being in AZ, you may want not only an extra trans cooler, but also an ATF temp gauge. -mike http://www.pbase.com/paisan/image/91072632.jpghttp://www.pbase.com/paisan/image/141039922.jpg http://www.pbase.com/paisan/image/133406601.jpg http://upload.pbase.com/image/137566671.jpg 11+ Years Maintaining, Modifying and Educating TriState Subaru Enthusiasts.

Cyclozene Posted March 1, 2012 Author Share Posted March 1, 2012 I was thinking the same thing. Do you know what temperatures the atf fluid can get to? Because I see a catch 22. The atf fluid is with the coolant which is what 200 some degrees? So unless the atf fluid is hotter than that wouldn't it be warming up? Idk haha Thanks for input Link to comment Share on other sites More sharing options...
bmx045 Posted March 1, 2012 Share Posted March 1, 2012 your fluid will roast if you're in traffic. the reason the atf goes through the radiator is to quickly bring it to op temp (>160*) and to maintain it along with coolant temps....and you have fans so it keeps both the coolant and atf no greater than 210 on a real hot day. Atf gets EXTREMELY hot because of torque converter friction. install a fan on the cooler to turn on when atf temps get above 200 via a thermostat...that would be my recommendation....they sell cooler/fan combos on fredbeansparts.com. also a thermostat and fan equipped external oil cooler will do the trick too. summitracing.com has those Link to comment Share on other sites More sharing options...

Cyclozene Posted March 1, 2012 Author Share Posted March 1, 2012 Thanks for the info. I have not been able to take off the stock radiator and look at it but how much surface area does the atf cooler have inside the radiator Link to comment Share on other sites More sharing options...
Mega Users seabass07 Posted March 1, 2012 Mega Users Share Posted March 1, 2012 Keep in mind that a liquid cooler will be much more efficient than an air cooler. If you were getting a massive external atf cooler, then it could be ok. But the ones that most of us on here use are way too small to be the sole cooler. Don't underestimate the amount of heat the torque converter can make. If you log both atf temps, you'll see the temp difference between the temps in the torque converter and in the atf pan after it's been cooled. When it's warm out and you are driving aggressive, it can be a big difference. Link to comment Share on other sites More sharing options...
AZP Installs Posted March 2, 2012 Share Posted March 2, 2012 My first road race car was a 97 impreza L 4eat. We used an external hayden trans cooler from summit. The largest one we could find. It kept the temps in a good range coupled with redline high temp atf. We ran several endurance races with it and it also spent a few weekends on track at watkins glen for 7+ hrs straight. After we put 40,000 track miles on it starting with110k to begin with, we used that trans in a street car. So, my suggestion is to do a huge cooler, redline high temp atf and change the fluid and filter often. Mike Link to comment Share on other sites More sharing options...
Mega Users seabass07 Posted March 2, 2012 Mega Users Share Posted March 2, 2012 But did you use that cooler on the street? How high was the stall on the torque converter? I know you beat on the transmission on a track, but you also always have air flowing through the cooler. A big cooler could be ok, but I'd be very concerned when it's 100+ degrees out.

The converter and tb were stock on it. Good point on the daily driven. We did the same setup on my 92 SVX which was my only car and was daily driven in manhattan as well as tracked. -mike http://www.pbase.com/paisan/image/91072632.jpghttp://www.pbase.com/paisan/image/141039922.jpg http://www.pbase.com/paisan/image/133406601.jpg http://upload.pbase.com/image/137566671.jpg 11+ Years Maintaining, Modifying and Educating TriState Subaru Enthusiasts.

Cyclozene Posted March 5, 2012 Author Share Posted March 5, 2012 Thanks for all the info guys. I'm looking at installing a temp gauge which should be interesting and I might even do a fan cooler combo. Depending on which cooler I get I may have to manually turn on the fan. What is the hot atf these days? Sent from my SPH-D710 using Tapatalk Link to comment Share on other sites More sharing options...
Max Capacity Posted March 5, 2012 Share Posted March 5, 2012 Wait a minute here, you say STI swap. Yet you only swapped the engine and not the 6-speed ? Why didn't you buy a radiator for a legacy with a automatic transmission ? You may want to check out Amsoil ATF. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

Cyclozene Posted March 6, 2012 Author Share Posted March 6, 2012 I just ordered a tru cool 11x9 I also ordered a 9 inch fan. I have a hayden 1677 now I went with the tru cool because of the unique bypass system. It's probably a gimmick tho. Now I need to figure out a way to install a temp gauge.

gingerbreadmanGT Posted March 16, 2012 Share Posted March 16, 2012 i just installed a temp gauge sensor into a mix of brass fittings on the after cooled line going to the trans. here is a pic... edit..actually after thinking about it, would it be better to check temps of the oil coming out or going into the trans? http://i1200.photobucket.com/albums/bb330/Gingerbreadg35/20120311_163302.jpg Link to comment Share on other sites More sharing options...

gingerbreadmanGT Posted March 16, 2012 Share Posted March 16, 2012 Yes its a stand alone unit. Im also just using a prosport oil temp gauge since it seems to sweep low enough. I guess ill be swapping hoses and the sending unit this weekend. Link to comment Share on other sites More sharing options...
