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.
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.
