Well, no more misfire codes. ( I believe p301 ) The car seems to upshift early. On slow acceleration, transmission seems to shift between fourth and fifth gear, toggling between each one until the speed is sufficient enough to remain in that gear. If I put the transmission in D3 and drive until I get to highway speeds and then put it in D, There are no issues. Upon heavy acceleration, there are also no issues. Is there a software flash that cures this issue? The transmission functions fine, but it seems like the electronics don’t know what gear to be in at very slow acceleration.
