5R110 5-3 shift bump during decel.

[Matt Saunoras]

This is my own 06 F-250 with approximately 118k on the clock now.  This problem developed over night so I took a few recordings this morning. A small bump is felt while slowing down around 18-20 MPH.  It appears it's on the 5-3 shift coming to a stop. From the looks of it SSD comes off and SSC comes on.  SSD as well as PC-A have been changed in this truck before.  I can see a small spike in TSS when the bump is felt and it syncs up with SSC as it comes fully on.  One time I felt a hard 2-3 but I missed the capture button because I wasn't expecting it. 

 

I am not a tranny guy but I am going to try changing SSC and see what it does.  This truck is due for at the very least a soft overhaul but I can't bring myself to open it up when it's still (for the most part) okay.

Had one brand new doing this. Bad solenoid.
