Help ID this bolt on LT230...

This bolt is leaking/weeping oil at the TC.
The bolt is facing front of the truck ('97 90 NAS). this picture was taken just below the auto transmission (transmission pan on the right of picture).
It bolts the transmission bracket to the LT230.
If I can identify the bolt, I can torque down correctly to stop the weeping.
Or maybe I need to pull the bolt, put some thread sealant and bolt it back up? Thanks!

Appears to be M8 which will be 25Nm. Thread sealing and/or locking compound should do the trick. Threads need to be clean first though.

Edit: May be M10 as One ten suggested. Forgot that ISO flange head M10 has same across hex size as non-flange M8.

It’s a 10mm x 30mm bolt and definitely needs sealant as it goes all the way through to the oil reservoir. Don’t use any longer than 30mm or it will hit gears.

That would actually make sense, considering its job. Workshop manual also has a table of fastener sizes to torque specifications. When a torque isn’t specified, you can measure the bolt and reference the table.
