Does anybody know why the 04 powerstrokse famous for tranny problems? Is their anybody that has an 04 that has had problems with the tranny? What exactly goes bad in the tranny? iv heard snap rings pop out and reverse planetary gear pins back out, is their a fix for this to avoid problems in the future. And would custom tunes just make things worse?
i roached the trans in my 04' at 185k miles my shift solenoid hung up during a burnout and melted all kinds of stuff inside the trans.... i dont think you will have any problems with custom turning... i have an 06 model trans now and trunning custom tuning and i love it!
love the street tune... havent used my tow pig tune yet... last trailer i pulled only weighed bout 25000# loaded..... id recommend his street race lite tune.... that will be the next tune i get for mine
have been runnning the extreme race tune from Innovative for a couple of years. I have an 04 and have no problems with the tranny. I don't pull to much of anything though. But I do launch it in 4x4 with 200hp shot of nos. Still no problems but if it swallows it's ass tomorrow I don't guess I could complain any lol
Check with the dealer. The problem with the '04 trans was covered under a customer notification and fixed under drivetrain warranty. Mine was done five years ago and I have not had any problems.
The Customer Satisfaction Program being referenced in this thread is Ford Field Service Action #04B24. It was supposed to address the issue of the reverse planetary drum snap ring "walking" out of the case, causing major collateral damage, which if determined severe enough, resulted in transmission replacement. The downside is, this program has long expired. I remembered reading on Protech message boards of LOTS and LOTS of Ford dealer transmission techs quitting because of this campaign.
Back to the topic at hand, it seems this issue was more prevalent on late-2004 and some early-2005 model years (even though 2005 model years weren't covered under this program).
i melted the torque converter in my 04,with 24,000 miles on it.
