Pressure readings to low in tcm control wires. Transmission to be replaced per dealership. Findings: under drive clutches worn out, sungears and assembly damaged with metal metal fragments. On 4/30/2015 and 59,215 miles, car returned to dealership for same grinding and clunking noises. Dealership performed another "quick learn test. " as of 5/19/2015 and 60,001 miles, transmission is still grinding and clunking on occasion during acceleration and/or transmission shift from reverse to drive. The vehicle also randomly "stalls" while at stoplights/stop-signs with no normal frequency. Even with a new transmission, same issues are still surrounding this car. Thanks.
