Trying to service a transmission line and can't find a tool that will work. Bought and tried the standard 3/8 and 5/16 varieties from local parts store and no luck. The sleeve that slides along the hard line is too thick to go into the fitting on the cooler. Searching the net hasn't yielding anything that looks any different than what I bought. And I couldn't find anything that specifically stated it was for a 2003 Expy. Any techies out there that can offer any help?
Finally found it. Why do they have to keep changing these things! It's not like they're actually improving on a design, they're just trying to make it harder on everyone to service vehicles themselves. Here's what I ordered if anyone is interested: Lisle 39960 Transmission Oil Cooler Line Disconnect for Ford.
