Rear transmission motor mount replacement

Hi,

If you are referring to the one in the rear of the engine, the engine mount cross member needs removed to access it. This requires the engine to be supported via a chain/engine hoist.

Here are the directions I have for replacement. The attached pictures correlate with the directions. I have to be honest, it is somewhat vague, but does describe the correct process.

I just need enough room for the breaker bar to loosen the rubber bolt on the mount. I have already accessed the other three bolts. The link is AutoZone's instructions, however the picture will nor expand successfully. which the intake manifold was removed. There are several items that require removing. https://www.autozone.com/repairguides/626-1999-2001/Engine-Mechanical-Components/Intake-Manifold/_/P-0996b43f81b3cb43

Do you need the directions for intake removal? Here are the directions. If you needed something different, let me know. The two pics attached correlate with the directions.
