Here is my experience I had a problem when you step on it and u rev it lets say up to 4000rpm and let go of the gas and up shift will be hard like you would dump a clutch in a manual transmission.my mounts ware gone one so i change them and it improved but still had the same problem.I had service D come up then i accessed the manual in the cluster reset all the service and the shifting has never been so smooth.No more clutch dumping up shifting don't know what happened but it fixed it self
