Engine/Transmission (1994 - 1998) Trans adapter 47re 4x4 Cummins

[bmw54]

Got the new line to replace plastic disconnect , it goes from side of trans to check valve.

the prob i am having is fitting for the side of trans on the new line is bigger than old line fitting.

anyone know where to get the right adapter?.

looks like 5/8 -18 down to 1/2-18.
