DaveT Posted January 1, 2022 Share Posted January 1, 2022 I am looking for the part numbers for the big o rings that go on the differential side carriers for my 3AT transmission. I managed to find & figure out the shaft seals, got the right numbers from another thread here, and from parts on the transmission, and a parts supplier. 806727170 = 806727070 806727180 = 806727080 It would be great to have a link or a pdf for the books that list all of the parts of everything by using the diagrams with part numbers pointed out. The FSM only shows a part name, not enough info to verify / order a part. Quote Link to comment Share on other sites More sharing options...
somick Posted January 1, 2022 Share Posted January 1, 2022 I have bought them many years ago but never changed them. Since they were sitting in the same package I assume they all go to the driver side of my 3AT. I hope this helps. Sam 1 Quote Link to comment Share on other sites More sharing options...
moosens Posted January 2, 2022 Share Posted January 2, 2022 Recently saw a seller on eBay with some factory parts catalogs. Those will show all the details you ask for above. As I find time I’ll check my 1985 catalog that I have laying around. Should be the same p/n through the series. Quote Link to comment Share on other sites More sharing options...
moosens Posted January 2, 2022 Share Posted January 2, 2022 So I posted some pics on FB and then realized I had included a page showing the kit for a Manual. Hang on and I’ll locate the p/n for the kit for the automatic. I know you don’t need the whole kit , and it may be incredibly hard to obtain but for sure there’s guys sitting on 80’s NOS. This may work but it may ask you to sign in. I apologize if so. https://m.facebook.com/groups/730768337106149/?multi_permalinks=1985226878326949¬if_t=feedback_reaction_generic¬if_id=1641146833719147&ref=m_notif 1 Quote Link to comment Share on other sites More sharing options...
moosens Posted January 2, 2022 Share Posted January 2, 2022 (edited) The once upon a time part no. for the automatic 3AT (KIT) is X3131 AA000 and the manual version (KIT) appears to be X3211 AA000 Edited January 2, 2022 by moosens Quote Link to comment Share on other sites More sharing options...
