I'm doing a tranny flush i've traced the steel lines from the passenger side of the tranny to the radiator, but am wondering how to disconnect the lines? I'm thinking its where the steel line connects to the rubber hose near the front of the truck but didn't want to assume and mess something up. Thanks in advance for your help.

 

You'll want to disconnect the lines just as they go into the cooler. I wrote up a procedure on how I did this. I've done it twice now...I do this every 30k.

Auto Transmission Flush on 2004 F-150 @ 30k miles

 

DRM, I tried the search and it returned 17 pages of stuff ranging from fog lights to mp3 players and some transmission stuff, but I didn't see yours. not sure if the seach is messed up or what. Would you happen to have a link to your post? Thanks.

 

DRM, I tried the advanced search and was able to find your thread. so where is the best place to disconnect the lines to do the flush? Do you have a picture? Thanks again for your help.

thanks, VFR. I wound up only ubolting the drivers side line instead of both and it seemed to work fine.
