Should be somewhere in the area of .8 MKP or approximately 5.75 foot pounds. I also noticed on my tranny pan that there were three short bolts and one long bolt, all with "wings" to spread the pressure. I determined the long bolt went in the right front corner.
The prior owner or his tech had the bolts in the wrong holes and rather than move the one that didn't fit in all the way, he simply angled the wing so it caught across the pan lips. This caused a pinched seal and subsequent leak. I have had my pan off twice now and have had no leaks from the pan seal since getting everything where it belonged.
