So I'm about to finish up a b18a1 swap into my ED hatch, and I've found that I'm missing a tranny bolt (one of the tranny-to-block ones). Somehow it vanished while I was bolting the tranny back on.. dunno how, but that's another story. This is a stupid snag to run into!

The one I'm missing is on the rear, right next to the t-bracket for the mount (see image).

I've been through a lot of posts, and found a great site with an almost complete parts catalog (www.acuraoemparts.com), but still can't find this bolt as it's not in any online catalog I've run into. The tranny bolts aren't all the same - they are in 2 or 3 different lengths, though they all have the same thread and 17mm head.

This one is definitely shorter than several of the others, you can see it doesn't have that much room to bore in.

I'll probably end up just measuring what I believe the length is, but buying bolts is so much easier when you've got the part number.

Here's the one I'm missing, I'll post an image below I took before I removed the tranny.


Thanks for any direction.

 

Here's the best image I've been able to find, from acuraOEMparts.

The tranny bolt is #23. They say you need 16 of them, 8x40. The one I'm missing (it would be located to the lower-left of the diagram, pointing in towards the right) looks like it shouldn't have such a long non-threaded section just below the head, otherwise I'd just cut one of these down.

I guess that's an option as well, find another 17mm tranny bolt with a thread running right to the head, and cut it to the right size.

I've found some great information in other posts, but not quite what I'm looking for.

 

whoops, I think I can answer my own question, with this post here:

https://honda-tech.com/forums/acura-integra-6/someone-helms-please-help-me-out-tranny-bolt-size-1280756/
---------
2 Transmission Bolt [12x1.25x65]
3 Transmission Bolt [12x1.25x70]
2 Transmission Bolt [12x1.25x50]

Everything's in metric....the last number in each sequence is the length in mm's.
Use Grade 10.9 (metric equivalent of grade 8) flange bolts.

I'm probably looking for one of the shortest ones listed here.

 

Ah, this might be it. #34. I thought at first this was one of the stiffener bolts, but those are actually in a different diagram.

 

ok. im having the same problem. only that i dont have any of the tranny to block bolts. so this is being a PITA to find, i would like to kno the part # for those bolts please!!!!
