Tools you will need,
Full metric socket and wrench set either 3/8 or 1/2 drive.
(Remember its a Nissan so 10mm, 12mm, 14mm, 16mm, 17mm, and 18mm. Is what they love to use the most)
1/2-3/8 Adapter
3/8 & 1/2 Drive
Breaker Bar for those pesky trans bolts
Needle Nose or some pliers for electrical plugs that need disconnected
The way I did mine was A buddy and me when out and started at the rear, disconnecting the drive shaft, dropped the trans mount to be able to angle the motor-trans to gain access to the trans bolts better. Cut the exhaust right above the flange as to better clear the firewall. Disconnected the ecu side of the harness and pulled it back through the engine bay and then fully removed it from the engine as to keep the plugs from getting damaged. Put the straps under the exhaust manifolds and lifted it out of there. It took around 4 1/2 hrs to get done but that was in +98 degree summer heat.
