Im pretty sure this can/will work please tell me otherwise and explain reasons to why not. this is just a proposal. i might test it out on my car when i get my turbos and when its back up and running. but in the meantime just wanted to throw this out there.
Enjoy.

Pretty good idea, it will definitely work. One suggestion, maybe put the aftermarket core after the factory one. I feel like since the factory one has coolant running through it, it might warm it back up.

Interesting concept, so incredibly simple, too. I feel like theres a hitch...

I have already done this mod and the only reason I have not shown it or reported about it is my car is in the shop with an electrical problem. But the mod works well. I need more data before I can report definitive results here but my initially review is that it works flawlessly. Will post results soon...I hope.

Mine is after the heat exchanger which mimics the M3 setup. I also have a T-stat that opens at 180F to dovert flow to or away from the cooler when temps are over or under 180F. This allows for appropriate warming of the tranny fluid before the accesory cooler come into play.

I noticed you edited a bunch of posts in a thread about this. Was wondering whatever happened. If you don't mind my asking, is the problem related to the AT cooling?

Subscribed!! Very interested in this update.

My car is in the shop with an apparent electrical gremlin that is difficult to diagnose... but after 3 weeks it looks like we may have found the cuplrit. Unfortunately this electrical problem came about right after I got the cooler installed. This electrical problem is NOT RELATED to the AT cooler and a completely separate issue as the temp sensors are not even wired in yet. I was able to prove with an IR temp sensor that the outlet temps are 20F lower than the inlet temps of the accessory cooler. However this is only of the hoses so I would assume the actual fluid temps are more substantial. I will post pics and all info I can as soon as I get my car back and get some realtime data with the temp sensors wired into my gauge.

I expect to get the car back this week and then wire in the gauge and sensors this weekend. So hopefully by this weekend I can post all the juicy details.

subscribed! I hope this works out because the stock AT tranny cooler is a joke

It looks simple, yet affective

good work lil Sammy
