Since I bought my 2014 GT the transmission has always had a solitary clunk when coming to a stop around 50% of the time. It feel like 2-1 builds up pressure and shifts hard with a pop.

Lately, I've also experiencing some longer than normal shifts on what I think is 2-3 but I wouldn't classify them as flares.

The driveshaft u-joints are fine and I lubed up the slip joint properly. It's not my rear uca either. I'm not sure if replacing the valve body or molded lead frame will help.

Anyone experience anything like this?

 

Welcome,

Found a Couple Of Shop Manual Pdf's Which May Help!

So if I go through that diag and highlight everyone I deem applicable, the one common denominator becomes lead frame and regulator valves. However, I don't have the codes to justify it. Have we seen the entire valve body assembly needing replacement without throwing code?

 

All I Can Share is That Lead Frame was a Common Repair Back 7 years ago When I Was Still At The Dealership. Don't Recall any Conversations About Lack of Codes on The Repairs, Been awhile. I Defer To Anybody With Hands on Experience With the Issue.

If You Have Not Tried it, Might Disconnect Battery For 10 Minutes To Reset Everything and Go Through The Relearn Process and Check if Issue Stays The Same, Goes Away or Goes Away & Comes Back After Drive Cycle Completes. Then Check Again For Codes Again in a Couple of Days.
