Hi,
Does the vehicle have a 3.7L engine? If you look below, pics 1 and 2, I have an arrow pointing to where the torque converter is located (TC). That is called the transmission bell housing. The transmission and engine join together at that point and the torque converter is bolted to a flywheel at that point.
Also, at the opposite end of the transmission is the coupling. It is accessible without removing the transmission, so I'm not sure why one would affect the other. There wouldn't be a need to remove the transmission.
Let me know if that helps or if you have additional questions.
Take care,
Joe
See pics below. Pic 2 has the coupler highlighted.
