X2 - If replacing the motor the transmission mounts should be done too. Our motor mounts were shot along with the one of the two transmission mounts (funny they call it transmission mounts when the mounts are on the transfer case).

2003 Discovery 132K with all high miles service complete.

 

I checked Engine mounts and they are all new since the Engine was just replaced 2 years ago...
Also I have a Disco 2 S edition that originally came with the 4.6L turd that blew a head gasket.. The person replaced the motor and it has been leaking from what looks like a rear main seal..

Here is issue.. I am not exactly sure what type motor and tranny I have now because I was under the impression that the tranny that came with my truck did not have a drain plug on the bottom but this one does.. If so, where is the Trans filler hole? the one on the back looks way too low for there to be 7 quarts of fluid in it... Is it up on the side??

I have included a picture of the mount and a shot of the bottom of the Tranny but thats as good a shot as I can get... Thanks for help
