I have recently installed a Mishimoto radiator in my car and the trans cooler lines do not fit on the provided male screw adapters on the radiator. Does anyone have any idea how to keep these trans cooler lines on?? Every time I slip them on, they torque themselves right off!. It looks like I need a female adapter with an inside diameter of 12mm X 1.25 to a barbed nipple. Anyone have a solution to this? (I dont have access to a CNC mill btw) Thanks!

P.s. I searched for this issue, one other guy had the same problem however, there were no replies

 

Does anyone have any ideas? I have now searched 12mm X 1.25 metric to barb fitting all over the internet. any ideas?
