The bell housings are different for the manual and automatic transmissions.

Our terminology is always going to differ. But to me there is an engine bellhousing and a gearbox bellhousing. That's the engine one I posted up.
Some engines don't have an engine bellhousing, they use flat adaptor plate.
Here is a section through the centreline of the engine.
The flywheel is gold, you can see a slight difference in colour between the block and engine bellhousing.
The gearbox input shaft and support bearing haven't been added yet.
The Isuzu gearboxes use the gearbox bellhousing as part of the front case which includes the input shaft seal. They are removable and swappable, but expect them to dump all the oil on the floor when unbolted.
