I bought some of the ppkv2 pieces. This includes the oem brackets and core. I grabbed a tstat from improved racing and I'll be getting an AN fitting welded onto the oem core. That trans "cooler" which is actually a heater, is being bypassed entirely. This way it will all fit nicely including ducts from the 335is.

Oh ok. So bypass the stock heat exchanger completely and use a air to air cooler (15 row) with a 180* thermostat. Might even throw a temp switch with a fan on there.

No, it will be a normal fluid cooler core, I'm cooling trans fluid with it not air(or water) in this case. And I think i did a 165* tstat.

Do you guys monitor trans temp through MHD app or some other way?

I've read so much about pressure drop (theory) when running a trans cooler.. I guess no one has actually felt the negative affects of it. I plan to retrofit a trans oil cooler to go along with my PD built trans, along with an engine oil cooler here shortly.

For my trans cooler, I have the fittings from Omar.. I need a core (15row), 165 degree tstat and appropriate lines. am I missing anything?

As with any cooler (oil cooler, intercooler, etc) you'll have a pressure drop. However, the higher quality unit/materials used, the lower the pressure drop. Get a nice cooler (not ebay $50 lol) and youll have a small pressure drop.

Nope, just a few hours for install lol
