Hey all, first time posting here and hopefully many more. I have a 99 EX civic, with a D16Y8 in it. A few months back I did a full rebuild of the engine myself, now the transmission is starting to have some issues. Currently the ISB is going/has been out in it for a little while now and I'm finally able to get around to dealing with it.

First off, I attempted to order a new ISB online, and every site lead me to a "honda genuine shaft bearing" is this the same bearing? I've only heard it referred to as an Input Shaft bearing.

Second, while I'm in there dealing with that, I figure I might as well do anything else i can while I'm in there.(already doing a new clutch job as well) mostly I'm trying to find a diagram for this transmission online and I cannot find one. I would like to see what other bearings I am able to do while completing the ISB. This is my first time messing with a transmission, I've done plenty of engines before but excited to finally work on a transmission. Would you guys have any suggestions on what else I can do while doing this project? Thanks!

 

At what online site did you shop? The official Honda name for the transmission bearing is not input shaft bearing, and the transmission contains multiple main shaft bearings.

Also replace the oil seal, clean the magnet, and purchase some Honda manual transmission fluid and some HondaBond to reseal the transmission.

 

Already doing the rear main seal as it's got a slow leak. Already got hondabond and honda fluid, I guess I'm more so getting at which bearing to get, I might as well do them all while I'm in there.

This is the oil seal I got from hondapartsnow.com
Part No.: 91214-PAA-A01
Oil Seal (80X100X10) (NOK)

This is the bearing for parts geek:

1999 Honda Civic Input Shaft Bearing - W0133-1921222

 

You're showing the rear main seal for the engine.

The transmission input shaft bearing is coupled with an oil seal in the clutch housing. See parts #4 and #7 here:

While everything is apart, you may as well replace the two axle seals too.

 

Thank you, just ordered those, as well as #6,

I meant rear main seal when i first replied sorry.

Now to get the axle seals.
