Hello everyone, I need some help please,
Car is a 2009 n54 AT i replaced my stock heat exchanger for the transmission with an 25row Setrab auxiliary cooler! Now I wanted to upgrade my stock radiator to a CSF unit and figured I could go with an MT CSF Radiator since it’s about $100 cheaper and don’t have a heat exchanger for the AT anymore! But here my question it looks like the AT cars have 2 hoses going to the passenger side of the radiator the lower supply hose and another hose coming from the water neck pipe (pump to block) is the smaller hose just a separate feed line for the AT heat exchanger! I’ll attach a picture and I’m talking about hose #10!

You should be fine to run the m/t radiator. I plan on doing the same when i upgrade. My a/t heat exchanger is deleted as well. #10 in the diagram has nothing to do with the heat exchanger

we have done this but converting the ppk aux radiator under the lhd side guard to a transmission cooler

you can easily use a manual radiator once you do that.

Gives you a lot more room for a 3"" charge pipe especially when using a ff manifold.

You need a new #11. Ask Speedtech to send you the manual part. It's the same as blocking #10.
