I have a 2005 4.0L Explorer with 104K miles and the O/D light and service transmission light has just started to come on. Of course it resets when shut off, and will start back up after @ 5-10 miles of travel. The error code thrown is P1744 which looking up the code seems to indicate the TCC system is mechanically stuck in off position. The thing is tho that when running the vehicle down the road to get the code, the scanner showed the tranny went to 100% lockup every time. Does this sound like a solenoid issue, or more likely mechanical? Want to try to fix the issue myself if possible. I believe the tranny is a 5R55S, with door tag code of V for Trans.

wow, no one replied, was hoping someone had the fix.... what ever became of your issues and how did you fix it?
 






Shudder fixed but had p0741

NO MORE SHUDDER, ALL FIXED

Well today I got my 02 Explorer back from Walters Transmissions in Temecula CA. I was going to take it in to AAMCO where they pulled a P0741 and they said it needed a full rebuild and it would start at $1500 not including parts, as I wrote earlier in a post in 2012 I had same AAMCO do a complete rebuild and paid extra for the lifetime warranty which they now won't honor due to a stolen receipt from same explorer. So after talking to the guys at TRANSGO they told me of a trustworthy person they deal with which is Walters. I just drove it 50miles without any shudder or other issues, ran great. Let me again tell you what I have done till I threw in the towel and took it in. I bought and replaced the solenoid pack (rebuilt), put in a new TRANSGO shift-kit (not incl pump part due to couldn't drop trans), replaced int/od servo with oring type, checked bands each time I touched the trans, the separator plate was in good condition, changed the filter 2x during the process, the pan was always clear of any debris other than a little normal black sludge on the magnet, the fluid when I first dropped it was good, and probably drained the fluid 3x during the whole process of when I started on this adventure, even tried to drain the torque convertor but didn't find a plug as I marked it turning the engine by wrench looking up at it through the access cover (I marked an X on it with perm black marker to make sure I did do a full revolution to find plug, but no plug was there), I always torqued everything to specs (I always buy factory manuals for all my vehicles just for reasons like this). The trans looked great up to this point since it was rebuilt back in 2012 by AAMCO and I even saw the new sleeves when I did the servo-bores. So at that point I started looking for a misfire somewhere. I ended up changing my plugs, plug wires(yes, I did find a white spot on at least one wire), coil, air filter, pcv, fuel filter, and did the full reset of the memory by disconnecting the neg battery cable and jumped it from the positive so it could relearn the shift values (can find on youtube). At that point I talked to Mark and Larry at TRANSGO and got Walters info. I have a 69 mustang that is using all my trans stuff to drop another trans. I took the Explorer to Walters Saturday and on Monday they called me yesterday (Wednesday) and said after all the test I needed a new torque converter, I gave the go ahead and they told me it was done today. They also found a kinked evac line which they fixed which may have caused a misfire but not the shudder. They also checked it over pretty good, no other issues. As I was there today, I saw the the converter they pulled out, and it did have the X I marked on it. They said it was stuck pretty good onto the flywheel and took some to get it off. I just drove it home and it runs great. Yes, it's only been a few hours, but if you don't see any more post, you know it's still working. Hope this helps. Lesson learned, always pull your codes first and use a person you can trust. Walter did the job for half of what AAMCO wanted.
