    2002 A4 with CVT , no drive in any gear, fault code P0730

    Guest-only advertisement. Register or Log In now!
    Can anyone give me any advice on trouble shooting the problem with my CVT transmission?

    The car does not move in any gear.

    The PRND indicator shows the correct gear but car does not move.

    Using an OBDII reader I got the following code P0730 / 17114.

    code P0730 is an Incorrect Gear Ratio

    which i believe means that your transmission is going out, or is already out
    i could be wrong

    good luck!

    sorry to hear this bad news. I am surprised there is no major lawsuit out there because these transmission seem to be going out before the 100k mile mark.

    How many miles? How often was the fluid changed?

    At our shop we recommend the fluid be changed every 20k miles on these CVT tranny's. Otherwise they start to have problems.

    The "incorrect gear ratio" code is basically a slip code. According to the ECU, the input rpm (engine speed) and output rpm (wheel speed) is impossible in the selected gear. This is usually due to the transmission "slipping" excessively.

    Manual swap would probably be a good option. A used CVT would another option, but make sure to get one with low miles and some kind of warranty. Good Luck.

    The car has 140k, I'm not sure about the fluid interval change as I recently purchased the car.

    I have thought about a manual swap but can't find any positive information on all components needed for the swap.

    Has anyone rebuilt a CVT? If the code is due to transmission slipping should I try rebuilding it?

    I see the O1J Audi CVT Master Rebuilt Kit on ebay is $625.00

    Many thanks for the advise.

    The only "rebuilding" i've done on a CVT was replace the slipping clutch pack for about 2 grand. But sadly I think your problem is worse than my situation was b/c i was still able to drive my old car.

    If I'm not mistaken there is an "updated" multiplate clutch assembly - 6 plates instead of 5 or something like that. It is often replaced as the early ones failed often. I kind of doubt that is your problem because if the clutches were worn it would probably still move. They usually drive quite poorly for a while before they completely fail. If yours failed 'all-at-once' then it is likely something else - and a new or used replacement tranny (or manual swap) is in order.

    If you change the fluid often, don't chip the car, and drive it normally it may last quite a while.

    If you are going to buy a rebuild kit make sure it has the 7 plate clutch pack design, or find a used one from an 04+ model which should already have the upgraded pack. www.shokan.com might have a used CVT if you want to go that route. The CVT isn't "super" hard to rebuild, but you will need a couple special tools to get it done right.

    How much does this typically run at the dealership? I have a CVT (67k) and I have always been worried about my tranny going ker-plunk. The dealership would be my only option for this me thinks.

    ^^^ The fluid for the CVT isn't cheap ($30 a liter i think) so it usually costs around $350 with labor to change the fluid. It should be changed every 40k.

    Alright thanks. Is it on the Audi recommended maintenance or would my previous owner had to have requested it to be done? (Because I highly doubt they did.)

    The first fluid change "used" to be covered by audi under the 40k maintenance. So it should be in the dealerships previous repair history, if he had the 40k done at the dealer then its been changed already. I think it was 06 that audi stopped covering the maintenenace services under warranty, so i think yours should have been covered.

    auditech79,

    You mentioned that CVT isn't "super" hard to rebuild but that you will need a couple special tools to get it done right.

    What are these special tools and where can I get information on rebuilding the transmission. Any information/insight that you can share is much appreciated.

    Have you rebuilt a CVT? I'm planning on taking the transmission out within the next few week and see what is worn or damaged.

    I've done the audi TSB for updating the clutch pack from a 6 plate to a 7 plate pack. Its hard to explain the tools you need without seeing a picture of them. You can make due without them but its best to have them. I would highly recommend buying a bentley manual which will have step by step instruction of tear down which you need, the dealer can also sell you the tools to do the job, but they may need to be ordered. If you want to buy the tools for the job but don't have the part numbers, ask them too look up the TSB at the parts counter and it will have the related tools listed. Basically snap ring pliers, pullers, punches etc.

    Edit: found the TSB related to your repair, the parts/tools are listed towards the bottom. Read the entire TSB.

    auditech79, I bought my car in september of 08 with 44,000 miles on it. No service records so I assume there has been no fluids changed reguarding the CVT. Do you know how many liters it would take for me to do it myself and where I could get it? Also, is there just a plug to unscrew as with oil or is it much different? Thanks

    6-7 liters, make sure you get the fluid from the dealer as its a special kind. The CVT REQUIRES a couple special tools to change the fluid, you need a special socket to take out the drain plug, and the fill tool which threads into the bottom of the pan. Its gravity fed into it while its running, and it has to be a specified temperature (vag com needed) to get the correct level. If you are a novice when it comes to transmissions, i don't recommend replacing the fluid yourself.
