For a simple manual front wheel drive car like a 04 Honda Civic, or any Honda Civic, what parts should be replaced that are easier to replace when the transmission is out? I'm replacing a manual transmission and I am replacing the rear main seal of the engine, input shaft bearing, clutch kit, and flywheel. Also the slave cylinder, just for s****.

Also relating to transmissions, are there any automatic transmission specific parts to replace when replacing the transmission? Thanks.

    Other than a throwout bearing, I think you have it covered. Commented Aug 27, 2017 at 21:35
  • Also if worn.. replace the spigot bush/bearing.

    You say you are dealing with a manual transmission , but you then change to automatic - which is it? As they are different.

The few car designs I know all use an engine carrier frame. That frame needs to be removed when removing the transmission (major work). So you could replace the silent-blocks, if present, that hold the frame to the unibody. Should the swaybar bushings be only accessible with the carrier frame removed, it would be also a good opportunity to replace them
