So this afternoon my trans started leaking. Turns out one of the lines going to the oil cooler has a pin hole leak. Does anyone know the part numbers for these hard lines that attach to the trans with banjo bolts? I guess the banjo bolt p/n's too.

I checked online but can't seem to find them. Hoping with the part numbers I will have better luck finding the replacements. Local Acura dealer parts guys haven't been the most helpful in the past.

So I found the attached drawing on the forum and the part numbers I need are for items 8, 9, 10 and 22. Can anybody tell me what these are?

#8 & #9 are the transmission cooler line fittings, #10 are the banjo bolts & #22 are the banjo bolt washers that attach them.
A big concern is your radiator- if the transmission cooler lines have developed pin holes in them, the transmission fluid cooler section in the lower radiator could be next, which will allow engine coolant to mix with your transmission fluid which will kill your transmission. This is kind of a common, known issue on these vehicles.

You can get a new radiator or install a aftermarket transmission fluid cooler & by-pass the one in the lower radiator.

Funny you say that...about two months ago the trans cooler blew an external leak and dumped the trans fluid. At the time I by passed the OEM cooler and added an aftermarket one with new rubber lines. I guess I should have taken a closer look a the hard lines coming out of the trans. Recently I started to smell trans fluid again and sure enough the one line was coated. When I pull the hose up the nipple a little I could see the fluid weeping out of the pipe where they bulge it. I went to an Acura dealer and they were able to get me the one that was bad but the other wasn't available in time. So right now I have a new line, banjo bolt with washers and need to get the other line eventually. Any chance you know the part numbers Acura/Honda uses for these? I sill need to get the other line and numbers would help. The guy I spoke to said he has never had to replace these lines and didn't even think they were available. It took him a while to find them. I might not be so lucky next time to get someone who will actually look.

The drawing you posted is an Acura exploded parts diagram from an Acura parts site. The part numbers associated with the ID numbers will be on the complete diagram Go to www.acuraoemparts.com and select the correct model, year, etc for your vehicle. That diagram should be under Transmission Case or something similar.

Thanks for the help. Now I can search out that part number and hopefully find it local. If not I will just order it since I will be travelling the next two weeks anyway, so I don't need it right away. Definitely going to bookmark that site though.
