Missing a bolt

I bought a 2000 preunner a few weeks ago, and currently am underneath it hand-cleaning old crud and gunk. I noticed a missing bolt on what appears to be the transmission. I'm not a well versed car guy. Anyone have 2 cents I could borrow? Do you know what bolt this is?

 

Is the bold missing or has it been sheared off?

 

Inspection plate bolt doesn't appear to mate to anything behind, You should be fine.

 

Looks sheared off to me, you'd have to drill it out and tap chase new threads and then you can put a bolt in it

 

Just an empty hole. Can't see threading at all, probably gunked, but no leak coming from it

 

If it isn’t leaking let it be.

 

I don't know what that hole is for, but it's not for a bolt. There are no threads in it, and there isn't anyting in it on my truck.

 

You definitely have an oil leak somewhere, maybe from the transmission

 

Yes, it seems I do.

 

I like to think my prerunner is pretty minty and it’s missing that bolt too.

From the front it’s missing (first photo), from the rear (second picture) there’s not even a throughhole

 

When you get all done with yours, will you clean my undercarriage? Yours looks awesome.

 

Haha are you being sarcastic?

Im sure ur boyfriend cleans ur undercarriage every day

 

Nice!

I thought it did sound sorta sexual, but I wasn't trying to sound that way. I was more teasing on how meticulous you were. It really does look awesome.

 

Really I thought it was dirty with the coolant remains from last flush 40k miles ago. Never actually cleaned the undercarriage. Unless one of those damn car washing machines got it

 

Interesting, on mine it does go through.

 

It's just an inspection cover. You can remove all the bolts and use duct tape if you really wanted to. It's just there to keep crap from flying into the tranny.
