ABSTRACT:
An adapter (70) for connecting a banjo fitting (44) of a transmission oil cooling line (21) to a flushing unit or cooler fixture hose (73) has a banjo nut (56') joined to a hollow tubing (71). Tubing (71) terminates in a flared end (72) which passes through an axial bore (45) of banjo fitting (45) and is secured by a radiator clip (74) within hose (73). Bore (44) has front and rear openings surrounded by ring-shaped external surfaces (46). A sealing nut (75) threads onto a threaded shank portion (57) of banjo nut (56') to establish an "O"-ring (76) seal against one surface (46) about tubing (71), and to seal the other surface (46) with a washer (63) at an underside of a head (58) of banjo nut (56').
