Part Numbers for Tranny & Diff Washer - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

BRZY · 08-25-2012, 06:12 PM

Looking to drain my transmission and differential fluids out and fill them up with Amsoil. I tried calling Oakland Subaru/Toyota (same dealer) for these parts. The tranny & diff washers are special order since they do not stock them (yet?). As I understand from vast experience with Honda parts, special order parts are nonrefundable. Searching the forum, I found these part numbers:

Rear Diff Fill plug gasket: 11126JB000
Rear Diff Drain plug gasket: 1215710010

Can anyone confirm these are the correct washers?

Just in case anyone is wondering about the oil filter:
Oil filter: 15208-AA-130 (old style, better?)

I just went to both Subaru and Toyota dealer for these washers/gaskets. The Subbie dealer doesn't have any in stock and has to order them because he said the tranny is made by Toyota (Isn't it an Aisin AZ6?). He told me the tranny washers are over $8 each so I said no thanks and went to the Toyota dealer. Toyota tells me its over $11 each

. Anyway, these are the parts number I got from them:

Differential fill plug gasket: SU00300122 @$2.30 each
Differential drain plug gasket: TOY1215710010 @$1.50 each
Transmission fill/drain plug gasket: SU00303626 @>$11 each

I'm assuming the new "SU" parts number means they are Subaru parts? I only got the drain plug gasket for the differential since that is the only one they have now. I believe its because it has the old parts number and they used it for other vehicles also. I'm not going to sweat the fill plug gasket for the diff. I'm just going to flip the old one and reuse it. The fill plug is near the top and the differential is not under any pressure so I'm sure it'll be fine.

Just got a both pairs with part numbers quoted from Opie at Subaru. Rear diff drain and fill plugs look identical, but are both crush type washers. I recommend getting new ones to form a better seal. Price is 1.73 for fill, 1.98 for drain.

Yes, the transmission fill/drain washers are freaking $7.87 each. These are solid washers, and do not seem like they require replacing, but I special ordered these so I bought them. Though I got them at net price it was still freaking $5.19/washer.

Could there be another part # for SU00300122 ? I can't seem to find it in certain parts catalogs.

Copper gaskets from O'Reilly's can be substituted for transmission gaskets they say. OIL-TITE! PN# 65275 11/16", M18

Anneal, flip, and reinstall.

Part # references on belmetric website?

Transmission
2 flat washers - 24mm OD x 18mm ID x 2mm (drain and fill are same size)
Belmetric: GA18X24T

Differential
2 crush washers - 24mm OD x 18mm ID x 2mm (drain and fill are same size)
Belmetric: GCA18X24

The stock washers I took off the transmission were virtually identical to the Belmetric GA18X24T.
The stock washers from the differential were similar to Belmetric GCA18X24 but not copper. To be honest, if you wanted to you could even use the same ones used for the transmission. Just make sure to use a torque wrench to get proper torque to 'crush' the washers.

Thanks for the info, have you had any leaks yet? And it works like the original version?
