Hi all first id like to say great site..so I have a 2005 f150 5.4 triton 4x4 lariat..I have taken the transmission out 2 times now replace torgue converter 2 times and im getting the same crazy results...I got reverse but no forward gears..although when I bring up the rpms it sorta seems like it wants too move slightly but then my truck goes into fail safe mode..( iam stumped) iam mechanicly experience but man this is frustrating..any ideas help, please 🙏 🙂 cheers from Canada 🇨🇦

 

Check for codes with a scanner that can read Ford transmission codes.

 

You replaced the torque converter twice for no forward but has reverse?!?!?! What kind of twisted logic came up with that? The torque converter doesn't know if the trans is in forward or reverse, it does the exact same thing in forward and reverse. There is no way your problem could possibly be the torque converter.

Your problem is a failed transmission. Take it out (again) and this time either replace it or rebuild it.

 

Hi there, just wondering I've got a 2005 4x4 f150..will a transmission from a 2004 f150 work in my 2005 any info will help thanks

 

It's not a direct interchange, but as I said in one of your other threads asking about a 2007 transmission, it should work if it's out of a new body style 5.4 4wd, but may need some minor mods. Please stop starting new threads on this issue.
