TRNW-2: D7UF1 Hyundai dual clutch No move after replacement.

[Fred Whitaker]

  No,I didn't check. But the clutch was shot.  Our autel shows clutch wear,but I don't believe the Zeus does.  I pulled the actuator back off  an set it EXACTLY to 72MM. I made a measure tool the first one I worked on. There was NO slop at exactly 72 MM. I think the actuators have sensors inside to sense MM of travel.   I don't think it's the actuator. They now both move in relearn with the motor running for some reason.  With the Zues in Relearn both actuators travel a considerable distance 3 times and then aborts.  The Autel only tries once. There is a parameter on the Zeus that shows MM each clutch moves.  One actuator moves in reverse,the other actuator moves in drive. But it doesn't even slow the engine down when the actuators move.  At this point I am leaning towards the Kung Foo clutch.  I think we'll pull it back apart to see if something obvious went wrong.  Iduno,tomorrow is a new day,and who knows where it will lead LOL

Did you check with your scan tool the clutch wear? I have had clutch actuators be faulty and give you slipping issues? The way I check them is to “see what the “clutch wear “ on the scanner is before replacing the clutch?
It’s tricky now! Is it the clutch assembly or actuator??
Good luck 🤞

Did you attempt to drive it before relearn with the king foo clutch?

I haven’t done one of these yet but an old coworker has been at the Kia dealer for several years now. He said don’t attempt to do a relearn on the scan tool, it always causes problems, just drive it. He also said they don’t put clutches in very often, usually they replace the whole trans because of problems after doing the clutch only.

  I have a 2016 Tucson that was slipping under heavy throttle in odd gears. Worked fairly well under light throttle.
 Sooo Slapped a clutch in it. Set the actuators to 72MM.   But it now won't make it through relearn,and it doesn't move.
  There are 2 parts to the relearn. Key on engine off,and key on engine running.
 It makes it through the engine off part just fine. You can watch each actuator travel almost full length. Once it passes that part. It tells you to start the engine and it then starts procedure and says conditions aren't correct. It doesn't say what isn't correct and trips no codes.  It doesn't even try to move the actuators in the engine running part.
 I have tried With a Snap on Zeus. Snap on Modis,and an old Autel Elite. All stop at same place. The Autel says Something about not being happy with gear actuator position. But the shift actuator wan't unbolted,it was simply unplugged,so I can't see anything being wrong there,and it all worked before. Maybe it means clutch actuator?
  I am questioning how reliable my scanner software is for relearn. Wondering if anyone else has had lots of success relearning these after clutch replacement. I did one a couple years ago and it relearned. BUT I don't think there was that much wrong with that clutch.( Actuators might not been as far out of adjustment) This one was smoked.
 Now for the whole truth LOL  We got a Kung Foo clutch off of Ebay for like 250 dollars figuring we need to see if they actually work. Because they use these in Fortes etc.
 So I am now at a fork in the road.  Either tow it to the dealer and see if they can get it to learn with this Kung Foo clutch.  Or put an OEM clutch in it and see if  that one will learn with the scanners I have.
 Any advice?   TIA..... Fred
