2003 jeep grand cherokee, 4.0L, on the transmission oil cooler at the radiator, there's a 3/8" rubber hose connecting the cooler metal lines to the metal lines that run from the transmission. I cut one of these off last year to do a transmission fluid change. It recently started seeping at this connection point so i replaced the hose and used permatex aviation on the barb then put the hose on but it is still seeping. I reused the oem clamps, the spring loaded kind where you squeeze the tabs with pliers and it expands so you can remove it. I'm wondering if these aren't providing enough clamping force so I'll be replacing them with good hose clamps. I know when I initially removed the hose, I had to cut it off with a razor blade because it was practically glued on there with whatever sealant chrysler used. So, does anyone know what sealant chrysler may have used? And what sealant should I use? Any application advice? Any advice on the type of hose I use? thanks.
