Nutsert or Helicoil is the best way to fix it right but requires a special tool install.

Tap out and use a bigger bolt is easiest.

Weld up the hole with aluminum mig wire, drill and retap requires great aluminum welding skills.

Permatex makes a thread repair goop but there are mixed reviews if it works or not.

Pick your poison.............................;)

Is there any kind of high pressure in the pan?

Like It's a through hole may be that I can simply use a longer bolt an put a nut at the other end?
Not much pressure in the pan area but like 300 lbs interally. but trans fluid is so thin it leaks real easy.

I allways Permatex the gasket on both sides and install and let it sit 24 hours before adding fliud for a tight seal.

The best stuff I ever used was windshield urethane, never, ever leaked but was a bear to clean off your hands and anything else it gets on.

Hopefully you get a rubber gasket with you filter, cork doesnt last long.

"Tap out and use a bigger bolt is easiest"

That's Funny Doug!

Don't you remember what did happen the last last time I tried to do that :)

This time I will drill before tapping out

Second brroken bolt is now out. The hole is way more cleaner than the first one (no broken plug)

Now I need to take some time to choose what to do with the first hole. I am really scared by this one. It has got a conic shape and I believe I have to partly fill in it if I want to avoid a serious leak.

I will use some permatex plus the gasket but.....

Finally I have decided to use a good tap.Today I Finished the two holes and clean everything. I bought 11 new bolts of the original size and two bigger and guess what.... the 11 don't fit. The originals have that strange thinner tip and I found out why today.

So NOW I have to find 11 bolts that fit.....

3 weeks to change a transmission filter.... I can't believe it

Thanks Doug, I will keep that for my archives, very helpfull.

The new pan is now in place. I re-used the original bolts after a good cleaning. I also used permatex.

Now I will wait tomorrow to put the ATF. I am scared to see a big leak tomorrow.

Cross your fingers.

After that, I will need your help to find out how this engine can run with so much hoses and connectors not plugged :)

Thank you Doug

Does the car still have the Emmision sticker attached like this?

Yes the sticker is attached.... I feel stupid one more time :)

I put the ATF this morning and....................... the thing doesn't start.Come on.....

The battery is fully charged and everything seems at the right place. I don't know, may be I have to kick somewhere :)

Sounds like not enough power. The dashboard lights are OK and strong, the awful noise for the open door is OK too but when I turn the key, nothing (no noise, nothing) except that the light is getting low

do you have a voltmeter, should have 12.75 volts on fully charged battery. Check the battery cables for bad connection.

13.12 Volts when I touch the connectors, I can have a little and single "Click", then the GEN light get low.

I will try to boost with my other car when mama will be back.

Hey; I am finaly not that stupid, on my sticker, there is no schema. But on the left, we can read BC 350 CU. IN. 40J2

May be:

BC for Buick :)

Car did start after trying to remove and play with the battery cables (thanks melsg5)

No trace of major leak on the pan but I put a lot of ATF more than 6 liters and the deep stick still says low and I didn't engage any gear
