starionesir Posted January 22, 2015 Share Posted January 22, 2015 I see the quote's for overcooling which is a real thing. If you don't believe me by all means contact climberd maker of the much loved hexmods valve body. As we all know fluid needs to be at a certain temp to work effectively. Trans is no different. Too hot means a problem too cold much the same. Link to comment Share on other sites More sharing options...

ivonr Posted January 22, 2015 Author Share Posted January 22, 2015 Link here http://legacygt.com/forums/showthread.php/properly-plumb-your-5eat-transmission-cooler-221643.html quote from that forum link: "Stock. This is fine for most people. It's not perfect. ATF can be overheated, and ATF can certainly be over-cooled, in the way the car comes from the factory. This is an acceptable setup for cold climates. It is not a good setup for hot climates that have a lot of stop-and-go traffic or mountains, and is not great for towing or road course racing. If in a hot climate you do many back-to-back rounds of acceleration, or create heat some other way (towing) then you should invest in a transmission cooler, and should strongly consider a bypass thermostat as well (more on that later)." i am going stage 2, but don't really do any of the above activities...do i really need this?

landark Posted January 22, 2015 Share Posted January 22, 2015 did you have to do transmission cooler or any mods like that? I was concerned about it initially, read about Hexmods and realized since I am not going beyond stage 2 I don't need anything like that for the type of driving I do. I have considered and am still considering a transcooler, just haven't gotten serious about it. Again, I only use my car for daily and the occasional spirited driving, so I am not really in any hurry. Doing my 60k trans fluid change last year it looked really clean and smelled good. If I ever decided to go autocrossing or to a track day I would absolutely be getting a cooler at minimum. Link to comment Share on other sites More sharing options...

landark Posted January 22, 2015 Share Posted January 22, 2015 The one thing I have read on here multiple times are horror stories about hard launches, so I avoid them and never pre-load and launch. I think you'll be ok, maybe put a cooler on your to-do eventually list. Link to comment Share on other sites More sharing options...

ivonr Posted January 22, 2015 Author Share Posted January 22, 2015 we'll see how my driving habits change once i go stage 2. who knows, maybe i'm constantly flooring it and decide the cooler is needed...at least it's not costly Link to comment Share on other sites More sharing options...
AMileHighLGT Posted January 23, 2015 Share Posted January 23, 2015 it's not absolutely required. Do your research. You can get away with it and the result is that your car will temporarily go rich during throttle lift (shifting). Is it not optimal? Yes. Is it worth it to have someone convert you to sd? Probably not. Get a valve that is at least 50% recirculation and you should most likely be fine. Or get an adjustable one like a gofastbits. I have it probably around 15% vent to air and i can hear it just fine. 100% is just obnoxious imho. this Link to comment Share on other sites More sharing options...

starionesir Posted January 24, 2015 Share Posted January 24, 2015 Why are you going to knowingly set the car up wrong? I would never spend money on my car and do something that is not the proper way of doing it. Its your car but just to have some extra whoosh sound its not worth it. The stock valve works just fine till you start running much higher boost from a larger turbo. Link to comment Share on other sites More sharing options...
ivonr Posted January 24, 2015 Author Share Posted January 24, 2015 Conflicting info....post above yours (along with others) says it's just fine Link to comment Share on other sites More sharing options...
AMileHighLGT Posted January 24, 2015 Share Posted January 24, 2015 I didn't say it was fine. If it was me I wouldn't run a vtm bov, that momentary rich at off throttlw /shift would worry me. I like my cylinder walls oiled. I agreed with the post. Its not worth it to switch to a SD tune just so you can feel like Paul walker. I agreed that it goes momentary rich at shift, because the pcm believes it has accounted for the oxygen drawn into the engine and past the maf to calculate fueling. If you vent some of that at shift, or lift off throttle, and it get vented to atmosphere, all of a sudden there is a short time where it is rich, probably too rich. I agree that it is not optimal, meaning that it will possibly shorten the life expectancy of your engine, like starion said, why not do it right.

Max Capacity Posted January 26, 2015 Share Posted January 26, 2015 sorry, I'm slow... Just asking, did you talk with Dave before you started buying parts that he will have to tune your car with ? It's nice to buy parts from the guy who's doing your tune, he will sell you what he knows. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD).

It's nice to buy parts from the guy who's doing your tune, he will sell you what he knows. i did, he had no problem when i mentioned the BOV. nonetheless i may not put it on now. only other thing i have is the Cobb AP and hopefully a CNT DP coming soon. when i mentioned the DP he pointed me towards some gaskets and stuff that i should also get so it all fits. regarding Colorado emissions testing... after stage 2 it looks like i am doomed to fail, is this true?

AMileHighLGT Posted January 26, 2015 Share Posted January 26, 2015 If the readiness monitors for evap emissions, oxygen sensors and catalysts and have not run, they will put it on the rollers. At that time if you're catless you will fail. Link to comment Share on other sites More sharing options...
