You'll want adapter fittings to go from the factory trans lines to *insert choice of fitting style here*.
I bought adapter fitting from Black Market Parts (you need 2) --> http://www.bm-parts.com/index.php?ro...&product_id=59

You should also use a thermostat. This is the recommended one --> http://www.improvedracing.com/oil-th...65f-p-423.html

You'll also want to buy the coolant crossover pipe from the manual trans 1er. PN 17127548229
