Hello and welcome.
this is quite a big job. Especially if you are going to do it yourself, without a lift.
The main problem on this job is that the front lower engine mount is in the way of removing the pan.
The engine / tran assembly needs to be supported.
To remove that front mount, the engine will need to raised quite a bit to get enogh room to get the mount out.
Sometimes along with raising the engine, the rt. side of the frame needs to be lowered to get the mount out.
What else do you want to know sir.
