Transmission Cooler for 904 ?

Hi Frank,

You didn't say whether you were going to use braided or conventional rubber cooling line. If you plan to use rubber line the AA679 listed on my site will work. If you plan to use braided line, the B&M 70266 will work. Both coolers would be adequate for your application. The 13700 on the other hand, would be overkill, but you can never be too safe in terms of transmission temp. Do you have a temp gauge in the pan?

On the braided line size, 6AN hose will work with two 1/8"NPTx6AN male fittings.

Hope this helps! :salut:
