CVT Valve Body/Oil Pump Parts Source?

[dillon.leduc]

Hey everyone I'm somewhat new here but heres my story;
2002 Audi A4 1.8T FWD CVT multitronic transmission o1j
Car wouldn't move in forward or reverse runs great 180,000kms,
Did diagnostics with vagcom and found that the tcm was communicating properly with solenoids and there were no codes whatsoever and in park the wheels successfully stop so I ruled out drive chain and tcm.
After noticing the clutch pressure at 0bar and the transmission temp not rising at all with car idling, I pulled inspection plug and it seemed like the fluid was not circulating.
With no success on finding a replacement transmission I figured I had nothing to loose tearing into it.
So I removed the tcm and valve body.
Once I had the valve body on the bench I tried turning the pump shaft with no success (seized one way and felt like it was not connected to anything the opposite way.
I pulled the 4 bolts out holding the pump housing to the valve body only to find my main pump gear was broken and in about 10 diff pieces in there.

So now my question to you all is where can I find internal valve body/ oil pump parts? I'd like to replace only the broken gear in the pump housing and keep using my valve body (shows no signs of problems) but all I can seem to find is the entire valve body and pump together in 1 unit. Let me know what you think of my situation.

No way! The trans is fine simply needs the oil pump so here's my update:

1 - I figured out that it's nearly impossible to find internal valve body parts..
2 - I don't want to pay 600-1200$ for a valve body
3 - I knew of a guy that had a non working cvt with a different problem so I ended up grabbing that this evening for $120.

Tomorrow I'll be pulling apart my parts tranny and fingers crossed the pump is ok! Keep anyone following this I formed of my findings tomorrow.

Well good news and bad news, oil pump was fine in my new parts tranny. Put it in, filled with oil, ran car up to temp ensured fluid was good and went to go through the gears and the car stalls out going into drive and in reverse as soon as it tries to kick in the gear selection starts flashing and I get these two codes-

P1773 - hydraulic pressure sensor 1 - signal too large

P1741 - clutch pressure adaptation - limit reached

I'm thinking the clutch plates are siezed? What the heck!!

It doesn't sound like the trans is fine.

hmm no, I am really starting to dislike these transmissions. In the process of tearing down my parts tranny, inspecting the clutch discs and whatnot see if anything is good in there (reverse is!) and then pull the tranny out of the car I'm fixing and tear it down and see what I'm left with. Nightmare!!! I'm taking lots of pictures so in the end I'll post a picture heavy thread about what goes wrong with cvts..

Did you ever get to the bottom of this?
