All advertisements aside, they are $800 retail but it wont cost that much buying from reputable vendors.

Keeping that in mind, the benefit of the aftermarket radiator is primarly to make it easier to combat those temps.

As others mentioned, the water temp is controlled by the DME.

I'd imagine the Mishimoto Radiator with a lower thermostat/DME control would probably be able to scale down to the 190-200F range, it's an educated guess based on other platforms and my own experience with aftermarket radiators and thermostats.

BTW your price is off, we did not have it anywhere near $800 ( but then again i cant go into details or it would be considered an ad).
Anyways it was a joke, we are not getting the product back on the website .
I know its still Monday and people are in a bad mood but seriously you need to relax and enjoy your day

The reason why no one buys them is because it is for MT, which doesn't suffer the same coolant issue as the AT. People are interested here because of the possibility of AT fitment, which was not offered by Mishimoto (poor R&D on their part for not figuring that out).

Yes, MSRP was $800, but the lowest I have seen for those are still over $600, which is still a ripoff.

Anyway, most of us know how forums work these days, a lot of vendors here post quite a bit, which is totally fine by me if you can actually contribute to the threads with some useful information in most cases (i.e. the other vendor in this thread). But that's not the case here, or maybe because you left a bad taste in my mouth being the only vendor to sell those Wedge dp-fix at a whooping $130 back i nthe days, while even most of the other vendors know it was a totally opportunistic rip off... I am done with my rant here

Price of the DP fix like any other product is set by the manufacturer not the vendor.
and i was not the only one selling it, that other vendor was selling it too at the same price

its actually fairly difficult to incorporate a cooler within the radiator which adds significant final cost, that’s why many aftermarket radiators are only offered for MT cars, most companies start with off the shelf cores and then weld application specific end-tanks.

They finally got back to me. According to them, the 1st shipment was sold out, so they dont have any unit on hand that can give me any actual pictures of the radiator... Wonder who bought them? I have never heard the availability of this particular radiator until I stumbled upon it few days ago...

Anyway, I asked them a few questions about the core thickness, fitment, and how they retain the built-in auto trans cooler. See if they can get back to me on those questions.

So me getting the lower mishimoto thermostat wasn't a waste yessssssss lol

Could you not just have a standard MT radiator and use a separate remote cooler for the trans mounted in the fender well?

Well, I remember 135pat looked into this in detail. I believe the major issue was pressure due to the new cooler. Plus, a completely separated trans cooler might not be ideal for street use, since the transmission fluid really need to get up the operating temp asap for optimal wear protection.

Just to be clear, it has to be 2 in 1 radiator? I'm looking into something hence the reason I'm asking.

I'm far away from being an expert but this is what I'm thinking of:
Instal this on the return line going from the cooler back to the tranny
http://www.amazon.com/gp/product/B00...Y1QGN9CDKG2CDN
Or this:
http://www.amazon.com/Tru-Cool-Long-...mission+cooler
after the thermostat install small radiator like this:
http://www.amazon.com/Mr-Gasket-7365...mission+cooler
It will open only past 180f so it wouldn't prevent the tranny to warm up to operating temperatures.
When is past 180f it will bypass the return line through the cooler which can be mounted underneath the car body.
It will be low so that will help with the oil pressure as well.

+1
The trans fluid goes thru the radiator in order to heat it up quickly, then the coolant in the radiator keeps it around 190F-220F.
The best solution would be to replicate the OEM setup just with a bigger radiator with aluminum end tanks.

not ideal, trans fluid needs to be heated much faster

Heated? Do you mean cool down? This setup will not prevent the trans fluid from not heating up fast enough. That will happen at regular rate as the thermostat opens after 180f or other desired temperature and when it does the fluid will be cooled down right before entering the transmission again.

[TurboBimmer]

The issue with a seperate AT cooler seems to be oil pressure. To get it done right, you need to add an oil pump to the setup, which drives the cost up by quite a bit. I was quoted around 2k Euros. Yuck...

As for the no demand issue for an aluminium radiator: as mentioned it's now pretty established that MT cars don't run into coolant overheating issues, even at the track in summer climate. AT cars however suffer from the coolant getting heated up by the tranny oil through the heat exchanger.

So in EVERY thread about upgraded radiators, us 6AT guys have jumped in and asked for such a unit to be built. But either the vendor drops the project, it never gets through, or now these radiators are mystically sold out... I mean c'mon, it's not rocket science, or is it?? We've been asking this for years now! Someone has got to make it happen!

When first driving, the trans cooler needs to be heated, once at operating temperature it needs to be cooled or heated to operating temperature, bypassing the system will create cold trans fluid for a long time, longer then specified…

I'm not bypassing the system. Is inline addition to the existing system mounted on the return line, after the fluid has been cooled/heated.
The temp is not the problem. As explain to me by Cloud9Blue and also mention by Autobahn335i is the fluid pressure.

got it.

adding a pump is costly and impractical, OEM style cooling solution will work best, I'm surprised no vendor is tackling this, I mean they make aftermarket radiators for other AT cars for freaking sake

yes, but mostly for "old" make and models which had external cooler, like the e36 and e46 non M and M models, I believe.

[vwetish]

The new x5/x6 have this cooler from factory #17
I have discussed this with Cloud9blue a little bit already.
He said it must be higher than the heat exchanger #13
They seem to be at the same level on the new x5/x6
A lot of make and models with towing capacity offer this cooler.
The engine is the same. i6 turbo. I know, the transmission is different design and all but I don't see any additional external pump to support the pressure.
What they have done is installing a separate thermostat for the cooler #3
Similar to what I was proposing.
Space is limited on the on the e90 though.
I'm here to give ideas. To help...

[Cloud9blue]

If you have an AT car, please have a look at the space available down there at there, which is virtually none... And it only gets worst if you have aftermarket dual oil cooler, or like many of us here with AT, the PPK/335is aux radiator. There is very minimal space to play around, and then you have to route the line to ensure good passage and minimal contact with anything else to ensure no rubbing. It just a nightmare to DIY...

Of course, with enough determination, resource, and time, anything is possible. But to what end? Spending $200-$400 on lines, cooler, and fittings just to "try" to make this work seems like the hard way around solving this particular problem, while on the other hand, we can just source a proper all aluminum radiator, which is essentially just a drop-in replacement.

Especially, the price on CRF isn't so bad either at $500ish. Now we just have to figure out if they actually make it or just another vaporware like the AR design crap that was beta tested years ago.

Btw, are you sure that's a radiator? The placement of it at the back of the firewall suggests to me that it is a cabin air heater instead...

[BMWX1-35i]

I would love to find a aluminum radiator replacement to upgrade my 135 auto for better cooling. I can't believe no mfg has jumped on this.
