2005 Audi A4 1.8L Turbo CVT Transmission
Ultimately, we transplanted the transfer gears, planets and clutch carrier from the original transmission code HCP into the donor A6 core code HHZ. The donor unit had a good case and perfect ring and pinion gears as well as the correct shim set up. Of course along the way, we installed a master overhaul set, new chain and the new factory recommended update for this CVT transmission which includes 7 clutches instead of the original 6.
One thing every reader should take away from this repair blog is to take your car to a repair facility specifically qualified for your vehicle every 20,000 to 30,000 miles and have it properly checked for leaks. Don’t let a little oil leak turn into a major repair for you. Of course if you are in the Dallas Fort Worth Texas area, just call the service desk for an appointment to service your Audi CVT (Continuously Variable Transmission).
Where did you get the parts to fix the CVT? My shop says they can’t get parts to rebuild my CVT, a 2005.5 A4, 2L Turbo. Who is missing something here???
Eved, thank you for your comment on my blog. The answer to your question is a little complicated. Many repair shops including transmission specialty shops are not willing to do the work that it takes to repair the Audi CVT, however this may help. My master overhaul sets and filters generally come from a company called Transtar. They most likely have an outlet in your city. Any other parts needed can be purchased at your local Audi dealership (at least my dealership in Dallas, which is Autonation VW). If however your variator pulleys or ring and pinion are bad there are numerous other possibilities for good used parts. If you are close enough to Dallas to get the car to me, we can rebuild your unit as long as the ring and pinion or the variator pulleys are not destroyed. Please call the service desk if you’d like to discuss this further (972-755-5333) ask for Joe.
Hi Joe. I have a CVT with code HCP that got broken. I purchased a used core from another Audi with code WWO. Can I simply change the core and keep my original electronic parts without any problem? My Indy says that the code HAVE to be the same, but others that it can be exchanged as long as it has the same terminal (rounded in my case).
