So I'm trying to change my transmission fluid. I've already drained and dropped the pan and added more fluid. To complete the change, I'm trying to flush the torque converter by disconnecting the return trans cooler line, but I'm finding it's a real PITA.

I used the quick connect disconnect tool for Autozone. It was the metal scissor type. I'm not sure if the tool is just junk or if there's any corrosion or something else going on.

Since I can't move the truck without complicating the flush process, such as mixing old fluid with new fluid, I'm wondering if it would be easier to disconnect the return line at the transmission end. Has anyone ever tried this? Would it cause more grief than it's worth, or should I look to get a different brand tool?

Thanks!

 

The scissor type are too large and usually too short..I got a plastic one that came with a bunch of other sizes from pep boys.. you should be able to snap in on to the metal tube then push it in deep to release it.. no scissor type…

 

A little to late to help you but just did mine last week and I just used an adjustable wrench and unscrewed it from the trans

 

Only trouble with that method is, you don't flush the cooler and lines.
But if it's your only option, it a heck of a lot better than nothing.

I have a set of the scissor type and plastic set. Both have worked for me. Make sure there is no dirt or anything in the coupler or else you will not be able to get the clip to release. When you slide it in place, you have to be tricky and push it in while at the same time pulling the two lines apart
