These transmissions are not interchangeable and fitment should be determined by JATCO stamp code or VIN. The two transmissions have different bell housings where the starter motor mounts. On 3VX0C an opening for the starter is partially cut into the bell housing. On 3VX0A the starter motor is further back and there is no cut in the bell housing.
