I just bought my 01 tj and I'm missing the bolt on the transmission directly across from the oil drain plug. I'm admittedly terminology deficient. I would load a picture but I haven't figured that out yet.

Can someone tell me what size it is and where to get a replacement please?

Thank you!

The bolt shown in your gallery is one of the clutch dust cover plate to bellhousing bolts. Those come in two sizes, so it'll either be an M8x2.12x16 or an M12x1.75x50. If the one missing is the very bottom one circled in the picture, that's the M8 bolt.

Maybe I'm off-base here, but since there's nothing life/death about this bolt, plus the bell housing being aluminum, and the hole is a through-hole, how bout running the closest tap though there and appropriate size bolt.

Sure beats running all over town, mail order, and junk yard.

Edit, I just realized I typed mail order, I guess I'm old.

How many box tops are needed plus postage and handling? >:)

It's not a through-hole. The two on either side are, but the lower one isn't. Threads into the housing. I agree, not sure how important it is, but I am seeing a seep of fluid from that spot. I've cleaned everything I can reach to determine if it's the rear main seal, which is my suspicion.

Sorry, you are correct, not a through hole. I just finished my rear main seal and "have been" it that area very recently. Either way, I don't think it's real picky if you did want to try a tap, even if you did have to make a trough hole.

Good luck on your leak correcting. For the past several months I've been all around and under mine fixing leaks.

Mongo, I find it hard to believe that it's a "special", and like I said above, I've been in this area a lot lately. I just took my screw out, it's not Machine threads, rather, more like a lag bolt, or large sheet metal bolt.

I compared it to a 5/16 lag bolt in my hardware bin. Almost identical, my lag bolt threads were just a little coarser.
