My transmission oil cooler ruptured back in March. I changed both the engine oil cooler as well as the transmission cooler and i flushed the transmission. When it was time to test drive the vehicle did not move from park. I imported a transmission and it worked for the 45 mins drive from the shop. As I was about to drive into my yard the transmission malfunction notice came up and once again i could not put it in drive. I sent it back to the shop and I was told there was a code asking if the torque converter was changed. Drove the car back home and the same error occurs.What should I do? Currently the scan says that I need to change my battery and to update my software
