Help with identifying transmission

[507omar]

Hi. we got a couple of Hilux trucks and I want to identify which models of transmission we have in them, so I could use the proper service manual
I found no visible identifying badge or stamped mark on the housing of the transmisson due to dirt
Where should I look this info?

My go to is narrowing down with Marlin's catalog for vehicle type and then in certain cases looking at their pictures.

It might be helpful to know which trucks. Usually, but not always, transmissions were in specific vehicles.
