904 transmission, thrust Washer kit

Sounds like you got thrust washers for steel planetaries. Aluminum thrust washers, even if it has the same amount of pinions have the tangs located differently compared to steel planets. I ran into the exact opposite problem last year when I received washers for aluminum planets but needed them for steel planets. I got the correct ones from www.wittrans.com and suggest you think long and hard before doing business with Bulkpart. If the parts they send you do not fit or are junk (even if their new in the box) they will not refund your money, they'll just give you a credit for the next time you order with them. Ask me how I know!

BTW: don't trust pictures places load on their website. A lot of the time it's just an example picture, not the real item you'll receive
