04+ Trans Temp (Daily Driving)

Return line is the top one on the rad if you need to know.

Just to clarify how this is supposed to work:

A stock system send the transmission fluid through the radiator to cool. The problem with this is that the transmission fluid temp will "follow" your car's coolant temp.

An "in-series" system places a mini radiator AFTER the radiator to provide additional cooling of the transmission fluid after it has already been cooled by the engine radiator. This provides a mild improvement and a good option for most of us. Also, for those of us in cold climates, the warmth of the engine coolant will help warm the transmission fluid in the winter - a good thing.

A "standalone" removes the stock radiator from the system and the transmission cooling depends solely on an additional, appropriately sized, radiator for the transmission only. This provides the most efficient cooling but I'm not familiar with how to size correctly.

If you placed your transmission cooler before your engine radiator the transmission fluid will be cooled before the engine radiator and then warmed up again once it goes through the engine radiator. You likely will see zero improvement.

According to manufacturers of coolers running standalone is less efficient than in series. I could see how that makes sense though I am not sure I buy it.

**Russosaur** · 07-02-2014

I wanna hear reasoning on that, maybe for like lack or airflow or something *shrugs*. At least the the fluid wouldn't be heated from the rad so it would take longer to reach the same temps I would imagine.

they also have aftermarket pans with cooling fins on them i have no idea how safe and efficient these are... ZZP sells them.

**Russosaur** · 07-02-2014

For what ZZP charges might as well just put a bunch of chipset heatsinks all over the trans pan. It probably cools the same amount LOL.

**13aceofspades13** · 07-02-2014

that would be interesting... telling someone about your modifications, "yea i put a bunch of chip set heat sinks all over my transmission fluid pan, cools the fluid down when you take it too the track!" some die hard car guy would probably look at you like a idiot.

**13aceofspades13** · 07-02-2014

personally living in michigan i would want too run a aftermarket cooler in series rather than a stand alone, that way the engine coolant would assist in warming the transmission fluid up a little bit, that is my 2 cents.

What would be the best avenue of approach is a Yblock with a on off port. So you could switch fluid to go to factory cooler or the standalone

I thought about this aswell, seems like too much of a hassle.

I actually thought about something similar! Flip to stock setup for winter and in-series for summer

Am I gonna be screwed before I fix it

Just run it after the rad, and if you need to re connect the line you cut just use a double barb like you did for install with clamps. Not ideal unless you wanna buy a new line.

**theaceofspades** · 07-02-2014

Looks like I'll be taking it all apart and working on it soon. Making it stand alone

**theaceofspades** · 07-02-2014

The one thing I could **** up. I duck ip

**stocker** · 07-02-2014

I apologize if any of the material I've provided screwed you up. I edited it now, but one of my threads had a diagram with the lines shown wrong

No it was my own fault. I read multiple threads and I just messed it up. No big deal

It really wouldn't be a big hassle. You would essentially "tee" into the feed line and then just turn the valve one way or the other dependent on the time of year. It would be easier than going standalone, but leaving the stock lines, then barbing back into in series for winter.

Now that it has been mentioned, I may just do that.
