Flash: Transmission Diagnostic And Shift Enhancements
SYMPTOM/CONDITION:
Some customers may experience a Malfunction Indicator Lamp (MIL) illumination. Upon further investigation, a technician may find the following Diagnostic Trouble Code (DTC) stored in the TCM memory:
• P1DCD-00 - TCM Monitoring Processor Performance Multiple Clutches Locked Up.
In addition, customers may also experience the following condition:
• Bumps on 2-1 and 6-5 down-shift while braking."
I had the same clunk..they reflashed, and it was perfect for about 600 miles. It occasionally is doing it again lately.
Thank you for that but this doesn't apply to me or cars built before Nov 2016 mine is built after. Even though it's the sane problem. So the dealer is right I guess
this clunking noise is just happenening all the time now and I'm afraid to take it to the dealer without a known fix to have them just start hacking at it. That bulletin sent from Philthy looked great but on the bottom it has build dates but mine was built way after. I don't see how it should matter anyway. It says 2017 GC so it should be the same fix. Could they use this bulletin on mine even though the build date doesn't line up?
Edit: I just read the whole bulletin and it doesn't matter of VIN or build date. Thanks for the bulletin
See the thread below this one regarding "transmission clunk"..I started it a few months ago. The TSB seems to have corrected mine, but look at the latest post describing the fix as an adjustment to the rear diff...makes a lot of sense...hopefully that will take care if it for you..
Went to dealer for recalls. Did nothing for tranny. I have to say very disgusted with this SRT! For the price they charge and this is my 5th one it's horrible. This is the technology they've come up with in 2017!
