E40 torque converter

I just serviced my 1996 e40d transmission, new gasket, filter and solenoid pack. I drained my torque converter but when I was putting the drain plug back in it seems to bottom out with a few threads still showing. Should this plug tighten all the way against the torque converter or is this normal? I don’t want to strip it.

Mine has a few showing, was yours screwed all the way in when removed.

Ok thanks, that makes me feel better! I appreciate you looking. To be honest it was dark when I pull it out so I’m really not sure. I should have paid closer attention, this was my first time.

I completely understand not wanting to damage the converter. You don’t want to have to remove the transmission to replace the converter if you don’t have to.

Just for the future … you have an Electronic 4 speed OverDrive (e4od/ E4OD) transmission. Not an e40d, E40 or Ed40.

It's an NPT type thread, you can use gasoila or Teflon tape and snug it so there's no leakeage.

I don't recommend this. If some gets loose inside the transmission it can block an orifice or stick valve. The thread is designed to seal without adding any sealant. Don't add any.

I will try that if it leaks, thanks. I just snugged it up but it worried me it hadn’t bottomed out.

If you're really careful and don't get any inside the trans it's fine. If a small bit does get loose inside it has the potential to do a lot of expensive damage.
