I have a 2001 ss and can not figure out which fitting I need for the upper transmission cooler line at the radiator. I have tried Dorman parts #'s 800-604, 800-605, and even 800-606 and they are all way too small except 800-606 which screws in but does not tighten up all the way. Any help or ideas would be greatly appreciated. I have come across part number 800-721 but can not seem to locate it anywhere.

 

not sure where you've been looking, but have you tried Rockauto online?

 

Yes, I guesse my real question is has anyone else replaced this fitting/ line and run across this problem? I ran my vin and the recommended part was Dorman800-605 which is way too small my car is currently in the shop and no one can figure out what the proper fitting is.

 

how about trying gmpartsdirect.com click on the browse the catalog link.

 

Without a vin I came up with a GM part # of 52481097
