Automatic Transmission Torque Converter problems of the 2013 Dodge Grand Caravan

This vehicle has 61000 miles and check engine light came on. Took to dealer and torque converter lock up is out on the vehicle. Also on fron to hood there is rust deposit under paint. I have seen this on several Dodge Grand Caravans in same place.

Yellow engine light came on. 2013 dodeg Grand Caravan driven at 30-40 mph. Obd ii code p07040 - tcc value high. 102,555 miles. Torque converter rpm does not match transmission. Slippage most likely due to clutch. No significant symptoms. Occasional glitch on starting to move forward. Told repair to torque converter, clutch and transmission. Added xmission s/w needed update and xmission filters needed replacement. Both with extra charge. (fortunately I had lifetime warrantee - $100 deductible - whew). Total charge - deductible, s/w update, and filters =$250.

The contact owns a 2013 Dodge Grand Caravan. The contact stated that the vehicle was taken to the dealer several times because it drastically reduced speed without warning. The rpms increased at a high rate of speed. The dealer replaced the torque converter on the first visit. During the second visit, the dealer replaced the bearing along with the transmission assembly. The contact noticed that a noise progressed shortly after the repair and the vehicle was taken back to the dealer. The dealer was unable to replicate and diagnose the failure. The contact was waiting for a response from the manufacturer to determine if they could provide a repair solution to the dealer to prevent the failure. The approximate failure mileage was 40,000.
