Transmission Hose Lines

These two transmission hose assemblies connect from the transmission case to the radiator. The trick to removing these from the circuit is by first removing the retainer rings around the nuts (covered with plastic protectors), then pull off the quick disconnect tubings, the nuts are removed last. Removing the fittings attached to the radiator is simple and easier to follow.

I changed the seals inside the nuts and those on the tubings as well with OR-012 (O-RING BUNA-N 70 DURO 3/8 IN ID 1/2 IN OD 1/16 IN WALL). This was done on a Chrysler Sebring 2005 DOHC 4 CYL.

I should have repaired/rebuilt the hose assemblies since I dug this deep, but it was getting dark and there were no leaks visible. Hose assemblies have a service life of about five years, especially for petroleum based lines like these, but it is not uncommon to see cars with hoses that are over ten years old.

Installation was much easier. You can avoid accidentally cross threading if you screw in the nuts first to the tranny case, then insert the quick disconnect tubing, retainer rings follow, then the plastic cover last.

Take your old brake tubings, brake hoses, clutch lines, transmission lines, air conditioning hoses and engine oil hose assemblies here, . . .
