Ive ripped the secondary crossflow cooler off 3 times now, twice from a tow truck (airmatic issues) and once when my brother drove too far over a parking block in low mode. I have a 2005 E55 with the secondary cooler beneath the heat exchanger.

Has anyone developed a simple relocation kit yet?

Or at least a new kit that replaces the crossflow with something somewhere else?

Ive seen a few other people make some custom stuff but not really sure how to get all the fittings to marry.

Also does anyone know how high the pressure gets in the transmission cooling circuit? Trying to figure out if its a simple slip fit with band clamps or if I need to incorporate threaded A/N fittings etc.

I don't think there is a need for relocation of the cooler.

That sounds like the words of a lucky man who hasnt had to purchase a 600 dollar part 3 different times.

By relocating the cooler you create more problems then solutions, if i happen to have situation like you had, I would probably shop around for used parts.
What do you mean by Gearbox cooler underneath the heat exchanger? As far as i know coolant radiator shares bottom part with transmission cooler. Underneath the heat exchanger is engine oil cooler.
Correct me please if i am wrong.
If you are talking about small oil cooler, then you can simply install copper pipe like @UncleBenz55 did in his thread.

There is a lot of confusion about what the cooler is for on these forums. There are ads on ebay that list it as an oil cooler as well. However, mercedes disagrees.

Another interesting thing is that the mercedes rep suggested it was coded discontinued but she found one in alabama. I dont know if existing supplies here in the states and germany dry up at some point in which case we will all eventually be forced to create a different solution.

That is interesting, and how is it cooling transmission fluid if it is coming from oil filter housing?
Are we talking about same part?

That's a secondary ENGINE oil cooler.
I eliminated mine as it was not needed to make room for the air to water inter cooler.
Oil temperatures are never an issue.

Style_Front

Dunno. Mercedes insists its a TRANSMISSION cooler.

It's wrong in the dealers listing for sure.
