Matt Saunoras Posted June 4, 2013 Share Posted June 4, 2013 Alright, my truck is a 2006 6.0 auto and I have never been into a torqshift. Ever since I got the thing it would flare the 3-5 shift occassionally. Bought it at 54k and currently I'm at 94k. It's been progressively getting worse, now since it's warmer out it's doing it atleast once a trip and it's driving me nuts. I've done 2 drain and fills with LV and most recently did a 16 qt flush switching back to SP to see if it made any difference. It did not. I've already replaced the direct clutch and PC-A solenoids. None of anything made a difference. I've noticed this flare in a few other trucks probably because I'm more sensitive to the conditions it happens under, I can almost feel when it's going to happen, typically from a dead stop when the shift occurs at 2000 rpm it will flare what I'd guess is 50-100 rpm. Anyone know anything about what I should expect to find? If I tear into the trans is it likely I'll be able to see the problem? Would you attempt a full soft overhaul or just the direct circuit? I have never once gotten a harsh or delayed reverse engagement but I feel that will be coming next. Thanks guys Quote Link to comment Share on other sites More sharing options...
Aaron Posted June 4, 2013 Share Posted June 4, 2013 You might as well overhaul the whole thing. I talked a mechanic friend through replacing the intermediate shaft on his via text on the weekend lol. They're pretty cake to rebuild. Is your truck chipped? Quote Link to comment Share on other sites More sharing options...
Aaron Posted June 4, 2013 Share Posted June 4, 2013 You can grind the flats on an EPC solenoid for the direct solenoid, but it's a little more complex than that, that's just the surface of it. Quote Link to comment Share on other sites More sharing options...
Matt Saunoras Posted June 4, 2013 Author Share Posted June 4, 2013 Yeah I've kicked around the idea of a modified PCA as a direct solenoid. Not looking for a bandaid fix though, there has to be a reason for this type of failure. I've been in enough trucks to know that they don't all do it. I'm worried about going in to overhaul on a weekend. Without ever being inside one I have no idea what to expect, it's highly unlikely I'll have everything I need already ordered. Also no the truck is not chipped. I have rolled back to the original 2006 calibration and the concern didn't get better or worse. Quote Link to comment Share on other sites More sharing options...

From them you can see that with a 3-5 shift the intermediate clutch is disengaging and the direct clutch is applying. I would pay very close attention to that clutch assembly and all related mechanical and hydraulic components. If you need an exploded view of the parts look in the 2003 model year WSM. For some reason Ford left that out in subsequent years in the manual. I find it useful for identifying components and ordering parts.

I thought the same thing at first also, and I was like what the duece? But then I did a little diggin' and they put that section in the first part of the assembly section of the shop manual. Go figure, it states disassembled view but it's in the assemble section. Quote Link to comment Share on other sites More sharing options...
Matt Saunoras Posted June 5, 2013 Author Share Posted June 5, 2013 Alright lets say for kicks I bought a reman torqshift BUT I used an 08-10 model year transmission. Remans have a good warranty but I suppose I'd be voiding it by putting it in my truck? Honestly I'm not sure what I'm going to do at this point Quote Link to comment Share on other sites More sharing options...
mrbudge Posted June 6, 2013 Share Posted June 6, 2013 Pull it out, you will find a burnt clutch. Once the clearance in the clutch is too great the pcm can't properly coordinate the shift timing and you get a flare. I have almost never seen a hard part fail in one of these unless it is chipped. As long as there is no metal in the pan the solenoids will be ok. Don't forget to re-set your KAM when you are done. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted June 6, 2013 Share Posted June 6, 2013 Hard parts don't fail unless it's chipped? Ummm. Output sun gears separate from the output shells, planetaries exploding, low/reverse planetary pinions walking. The whole back end of the 5R110W has been updated. This is why you can't just buy individual pieces now. You can get all of them as a set. This has pushed many failures which could have been fairly simple repairs over the cost cap for me. I will say that most of these trucks if not all have been F450/550 models. Quote Link to comment Share on other sites More sharing options...

I will say that most of these trucks if not all have been F450/550 models. Must be one of those environmental things. We get F550 trucks that work on power dam construction that literally get dragged into the worksite with Cats, and when they drive them back to civilization it is on the floor against the speed limiter (lots of overspeed codes stored)and we are amazed that the trannies are the only thing that doesn't blow up.

Matt Saunoras Posted June 7, 2013 Author Share Posted June 7, 2013 The flare comes and goes but it's there. Verified it yesterday with IDS, anywhere from 50-200 RPM. Atleast I have some time to decide. I can't even feel the 50 RPM flare, it feels like a soft shift to me. 3-5 is definitely softer than the rest all the time. Cleared KAM, didn't make a difference. Ideally I'd like to find a low miles 09-10 6.4 torqshift, slap it on the bench and take my time with it. I feel confident that my trans isn't going to need any hard parts but I'd love to start with a more stout platform. All the torqshift internals I'm looking up start with 9C3Z telling me they were all updated in 09. Quote Link to comment Share on other sites More sharing options...
