Separating engine from transmission

This is a pretty involved process to remove the transmission from the vehicle due to this being a CVT unit. No matter if you need to remove the engine or transmission, you have to separate the transmission and engine so that process is the same in both processes.

I am attaching the entire process from the manual on how to remove the transmission which is what I assume you are looking to do.

Please let us know if you need other info and we can go from there. Thanks

Do you mean once it's out or how to remove the engine and transmission as a unit? If the latter the entire drivetrain is removed and dropped out the bottom of the vehicle, then you can separate the parts. It cannot be done with the engine and transmission in the truck as there isn't enough room for the two to move apart so either can be removed.
Please reply as to which item is the problem.
