Auto Transmission won't shift or go into park, grinding noise in drive

[hankooks2k]

Tried searching for this problem, either no one has had this problem or i suck at the search function.

Today I was driving, took off from a stop and then a couple seconds later i lost all connection to my drivetrain kind of like if the TQ failed. It just revved and I wasn't moving anymore. So i pulled over to the side of the road.

I put the car into park and the car started rolling back ( i was on a hill ). I could faintly hear the parking pin clicking as it was rolling. So i pulled the e brake up and put in Reverse, again no connection to the wheels, but there was a grinding and whining noise coming from the transmission or something. Then i shifted into Neutral and it was silent, then i shifted into Drive and again the grinding and whining noise came back, I can rev it while in Drive and reverse and the car doesn't move. So i put it back in park (even though Park wouldn't work), pulled the e brake up and got it towed to my work. (I work at a toyota dealership, I have a VCDS).

Is there anything common that i should look at first? I have a 2005.5 Audi A4 B7 Tiptronic Quattro. 125k miles. Anything I should be looking for in the VCDS. Also I do not have a Check engine light. My bluetooth APR Dongle showed no fault codes as of now.

Any help would be appreciated.

When was the trans oil changed?

[hankooks2k]

i did a drain and fill about 10k miles ago.

Genuine Audi ATF

Are there some type of shift solenoids i can test or something. It seems to me that it tries to shift or something and does not fully engage.

[JayDog747]

You're going to have to get it hooked up n check for any codes. I am unaware of any test procedures with vcds. There's a chance it could be the gear shifter. Just curious, how many qts of oil where you able to put in the trans?

[A4SANDBEER]

your PRNDS isnt flashing on your dash correct ?

[vtwinjunkie]

Interesting, If it was FWD I would say you broke an axle.

What was the trans maintenance history like besides your drain and fill? Not sure what the parking pawl has to do with the shifting but its interesting that they seem related.

Sorry I cant be of more help just talking aloud to spark thought!

[kegobeer]

If its a FWD you prob broke an axle.


FWD or Quattro?

It's in his original post - Quattro tip.

Damn. You were quick with a response lol. I realized that and edited like seconds after my post.

I sensed a disturbance in the force, that's why I was so quick. hahaha.

PRNDS is not flashing. Works like normal. What would the flashing indicate? I will be checking on the car tomorrow again. It's possible I didn't see it flashing?

When I did the drain and fill it was 8qts I believe. I bought the kit from ecs. So it wasn't a complete flush, couldn't drain the TQ.

No other transmission history. I purchased the car at 90k miles and did the transmission drain and fill at 110k miles or so. I don't understand the parking prawl having any relation to the problem either but it definitely does not engage into park.

I would look to make sure all of the axles are seated properly.

will do, forgot to mention I did take off the front passenger axle to reboot the outer joint. I'll check that out for sure when I get the car on the rack tomorrow

Also i hit a huge pothole last night. If the axle were to break, or cv were to fall apart. that can affect the parking prawl right? also maybe its sending the power to the broken axle because of the quattro? ill touch base tomorrow.

The PRNDS doesn't necessarily have to be flashing. If the letters are highlighted or flashing then there are codes stored in the transmission control module. It's the equivalent of a check engine light for your engine, instead it is a check transmission light for your transmission and there are fault codes stored in the computer. If that was the case then you need to have your transmission module scanned to see what codes were stored.

You get these symptoms with a Quattro when an axel is broken too. Ask how I know? I was sure my tranny was hosed on my dear departed B5 until I got under and grabbed the axles. I could turn one axle by hand with the car sitting still. And my symptoms were exactly as described in the first post. All the power goes to the broken axle, and it makes some noise as the broken CV joint spins around.

Oh ok then I would def check the axle! that would explain the park pawl as well.

[mtroxel]

...that would explain the park pawl as well.

Yea it does. It sure sounds like tranny but a broken CV joint sounds a lot like a broken P pawl. Check all four. As I understand it you can sometimes just see the CV boot all twisted up around the CV joint.

Did you find a solution? my 06 AT quattro just did the exact same thing!! Its sitting in front of a transmission shop now waiting to be checked out monday morning. Id love to be able to tell em exactly what to look for and have a solid idea of what this should cost. hope you got your machine back up and running!

[mtroxel]

Did you check the CV joints?

[o1turbo30v]

Use your vcds and scan the transmission control module for fault codes, people he would have to break all 4 cv joints simultaneously for the car not move, even if he broke the rear driveshaft the car would still move as a fwd.

OP I think your original guess is correct that the torque converter failed......or you suddenly lost all your trans fluid and destroyed it.

[mtroxel]

Wong on both accounts. One broken CV joint and all the power goes to that axle. Had that happen personally last January on a B5. Same result with a broken drive shaft. Car won't move.

what did it cost to repair?

[mtroxel]

what did it cost to repair?

Mine was just $70 for a re-maned axle, and about 1 1/2 hours to change it.

[Bavarianhd]

thank you. I guess we'll see what happens tomorrow!

[Bavarianhd]

well its not any of my axles.. they say theyre going to have to dig into the trans and see if its the spinal drive.. 7-800 to fix that.. if not that than its a trans rebuild.

Did you ever find out what was wrong with your Audi in this situation? I’m having the same exact problem with my 08 328xi. Please help
