Unussual bang's sound from transmission
 
Hi, I am about 6K miles on mine 2011 JGC Laredo now. I found that unusually strong bang like sound happened out of transmission area when I parked uphill or downhill first, start engine and shift to D or R second even with brake pedal pressed. Also same type of bang's happened if you drive 30-40m/h and first release gas pedal and then drive without gas and after apply gas again.
It happened before on mine JGC 2008, but not as strong and loud as on WK2. Does it mean something wrong?

Sounds like this should be looked at by your dealer. If possible, take a tech on a test drive to demonstrate the noises.

Mine is doing the same thing, not sure if its an issue though, would be more worried if a tech looked at it. The TSB for PCM did help with the 30 to 40 shifting bang.

What is TCB for PCM?
