quick4dr Posted January 22, 2010 Share Posted January 22, 2010 going stage 1 very soon, is it recommended to install a tranny cooler? i dont beat on my vehicle but the added safety would give me peice of mind. what model coolers are recommended, how hard is the install? This is what im looking at, Tru-Cool LPD thin, Stacked Plate cooler kit # LPD4451 Compact cars & small trucks, GVW rating 11,000 lbs. Low pressure drop cooler 4 x 11 3/4 Link to comment Share on other sites More sharing options...
fx4me Posted January 22, 2010 Share Posted January 22, 2010 I don't think you would need one unless you'll be doing break stands and/or launching it. I was stage 1 on my FXT with the 4EAT and had no issues. Link to comment Share on other sites More sharing options...
RIPjeep2002 Posted January 22, 2010 Share Posted January 22, 2010 Ive been stg1 for the life of the car(17k) and no tranny cooler. Now I am going stg2 around March and I have ordered the tru cool 4452. Already have the VB done. But for stg1 you will be ok. Link to comment Share on other sites More sharing options...
OmniEnder Posted January 22, 2010 Share Posted January 22, 2010 Stg1 for 7k hard miles and haven't had one stiff shift. When I go stg2 I'll be getting the mishimoto heavyduty cooler. Link to comment Share on other sites More sharing options...

silentracer Posted January 22, 2010 Share Posted January 22, 2010 A trans cooler was the first mod I did on the 5eat when I realized power mods were in the near future. For me it's peace of mind. It's not difficult to install, there's a DIY here on how to do it. Link to comment Share on other sites More sharing options...
korpsepatrol Posted January 23, 2010 Share Posted January 23, 2010 I ran a trucool 4454 on my car when i went stage 2 on my 05 5eat. It is mostly for peace of mind since 5eat transmissions seem to run quite hot. The install is not hard at all also, there are several instructions on this site that i used. moved to transmission section.. 2008 6mt Legacy Gt Spec B DGM - Not so Stock/Work in progress 2006 5mt Legacy Gt OBP - Sold 2005 5eat Legacy Gt OBP - RIP R.I.P Coxx Link to comment Share on other sites More sharing options...
m sprank Posted January 24, 2010 Share Posted January 24, 2010 4454. All 5EAT's, even stock should have one. Link to comment Share on other sites More sharing options...
fishbone Posted January 25, 2010 Share Posted January 25, 2010 Any cooler that has a cold bypass feature and is decent quality should be good for you. TruCool are relatively inexpensive at under $60 Link to comment Share on other sites More sharing options...
quick4dr Posted January 28, 2010 Author Share Posted January 28, 2010 what unit with cold bypass is recommended? Link to comment Share on other sites More sharing options...
fishbone Posted January 28, 2010 Share Posted January 28, 2010 Any decent unit. TruCool has the feature, so does Hayden. Just make sure the model you buy has it. Link to comment Share on other sites More sharing options...
scoobydoobie Posted January 30, 2010 Share Posted January 30, 2010 I wouldn't say you NEED a trans cooler, but it certainly can't hurt anything. I have been stage 2+ on my totally stock 5EAT since August and haven't had any kind of problems with the tranny. Link to comment Share on other sites More sharing options...
loopless Posted February 3, 2010 Share Posted February 3, 2010 You realize your transmission is pretty smart - it monitors the fluid temperature and if it ever gets too hot an alert flashes up on the dash panel? It will also hold lower gears in order to warm up to operating temperature as fast as possible - in cold weather I am guessing a cooler could actually be counter productive. I am sure many will disagree but I can't see any need for a transmission cooler unless you are towing or otherwise pushing the transmission doing autocross etc. Link to comment Share on other sites More sharing options...
fishbone Posted February 4, 2010 Share Posted February 4, 2010 I disagree First off, the aftermarket coolers we are installing have a bypass feature built in. When the fluid is too cold, it does not get routed through the whole body of the cooler. As it warms up, it gets routed increasingly into more of the surface area. How well this feature actually works hasn't been documented but come next winter I will have a temp sensor and I'll know for sure. The factory transmission cooler (yes, there is one) is either built into the radiator or is attached to the bottom of it from what I could tell. I guess if we can confirm that the radiator part # is different for automatic units, we'll know. When modified, the transmission is seeing an increased amount of torque. The VF40 hits it hard and hits it soon, below the stall speed of the torque converter. This heats up the ATF. Sure, you are more than welcome to make the decision for yourself that you do not need a cooler. However, most of us chose to err on the side of safety and get one. You will much sooner kill the transmission during summer than kill it because it is being cooled excessively. Link to comment Share on other sites More sharing options...
fishbone Posted February 4, 2010 Share Posted February 4, 2010 Here's a good read on TruCool http://www.dana.com/Automotive_Systems/images/PDFs/LNG039_Tru_Cool_2007_B.pdf Later edit: looking at that brochure, my wife's Mini comes equipped from factory with a cooler that looks like the long aluminium units on the last page. That thing is HUGE, it is almost a quarter of the size of the radiator. Fun fact: the 4452 has a BTU rating of 9800, which means it can shed the equivalent of 252,000 calories Link to comment Share on other sites More sharing options...
