Transmission Oil Pan Bolts

Transmission Oil Pan Bolts

Postby Rich G. [OP] » August 16th 2017, 6:34pm

Upon inspecting my 2005 AWD Astro I noticed one of the transmission oil pan bolts came out. Anyone have a part number and torque specs on this bolt? My searches have been inconclusive.

That's a great start. Thanks! Based on the note highlighted in blue in the FSM are we to assume a thread locking compound should be applied?

I discovered it's an M8x???. Not sure what the length is supposed to be. I had a bunch of M8's in the bin so I just used one of them with a washer & lock washer. It was a stainless bolt- any problem in using that? I'm always leery of using stainless due to corrosion of dissimilar metals and galling issues. I snugged it up just a bit to avoid having it stuck in there in the future.
