How do u take tranismission cooling lines off
Is this an aftermarket cooler? Most trans cooler lines are in one tank side of the radiator. OEM lines have a plastic cap you slide back and a semi circle clip you need to remove from the groove on the fitting and the line pulls out. Aftermarket coolers have a barbed fitting, start with a bladed screwdriver between the hose and fitting to spread the hose as you pull. After you get the hose moved back, needle nose pliers can be used to pry the hose as you pull. If you just pull on the hose it tightens on the barb.
