This car is getting on my nerves and I am about to sell it for $500 bucks or give it to the junk yard! Tired of this freaking car and my questions not being answered and throwing money at this peice of **** Audi Cars!
Parts are hard to find and expensive. Never had so many headaches until I bought an audi.

When I reduce speed by pressing brakes lightly coming to a full stop, car feels like it wants to stall then all of a sudden I feel a slam if I give it gas turning right or left or unto a driveway without actually stopping. Now when I am fully stopped and the engine settles. I can take off fine and it seems to shift pretty quickly and fine with just light pressure on the gas peddle. . I filled the tranny while the car is off, drove it , checked the level it is still full. Is the car suppose to be filled while engine is running? like our american cars with dip sticks? or is it fine to fill while the engine is off and we are under this lifetime bullshit transmission?
I already tried the reset method by pressing gas peddle all the way down while switch is on then release it after I put it on off. **** doesn't work. Does the ABS Module have anything to do with shifting? the Transmission control module under the rug is brand new. I bought it a month ago because the other one was wet and damaged. I also recently rebuilt my transmission on my own perfectly. I sent the converter off to rebuild and I am hoping it has nothing to do with the converter. I deel like its locking up and won't go into neutral quickly and smoothly when braking fast. If I brake really slow, it feels fine unless I turn or go into a driveway it feels like it will stall, and then all of a sudden slam! right back into second if I touch the gas. Last question, Do these cars have a TCC solenoid? I tap the brake while driving and I don't notice any difference in RPM while driving steady at 60 MPH. Car shifts real fast and solid forward. It it the slowing down and downshifting acting the hell up. I am $6000 in debt because of this Machine. I really am starting to hate it and I hope I don't have to drop the tranny again or BY god I will Junk it.

 

It sounds like rebuilding your own transmission may have been a mistake. Perhaps you should have an Audi specialist take a look.

 

Here is a link to changing the ATF on an A8 (same as your A6 4.2).
Read the instructions on filling the tranny as I believe that is where your issue lies, and you may be a few quarts short on fluid which could explain the behavior.

The car must be at ambient (cool) temperature before filling the transmission! This requires the car to sit overnight to completely cool off.

Install the new filter the next morning (don't forget the filter to transmission o-ring/gasket), bolt the pan up. Fill the pan with as much fluid as you can with the car off (until it starts flowing out of the standpipe, what I call the fill hole).

Start the car. Right away it will start taking more, give it about 20-30 seconds to start pumping fluid through the tranny.

Keep filling until it overflows. Should be 2-3 more quarts (initial fill about 4 quarts).

Have somebody run through all the gears for 30 seconds each (with the brake on), when doing reverse, the fluid will flow out, let it, then go through N,D,4,3,2 30 seconds each. This is about 10-15 minutes into the fill after the car started.

Let the car run another 2 minutes, then run it through all gears for 30 seconds again, do Reverse for a shorter time because it will squirt out.

Keep filling so it has a slight overflow at all times.

If you have the Ross-Tech software, monitor ATF fluid temperature on group number 4, under measuring blocks, transmission module. The temperature of the ATF fluid during this procedure should be 30-45 C. If the engine is operated for about 15 minutes from ambient temperature, it will reach somewhere around 45 C at the end of the 15 minutes. This is why the car must be cooled overnight. If you do not have the software, just ensure it was cooled overnight. It is not absolutely critical to measure ATF fluid temperature. However, you CANNOT do this if the transmission is not at ambient at the beginning of the fill.

You'll need a total of 8 quarts of ATF on hand, I would have 9 there in case you spill one...you just might.

I hope this is the solution to your problem as you already have done a lot of work.
Don't let the frustration take away the joy of driving your Audi.

 

What? Are you sick? Let another motherflower charge me $4700 bucks and not knowing what the hell they did? You must be insane if you think some mechanic cares about you or your car. I couldn't sleep at night not knowing what they did to the inside or not seeing for myself why it was slipping in fourth. Clutch pack "B" was burn't causing fourth to slip and go into limp mode. Now it shifts beautifully forward . But the problem is when you are almost coming to a stop.I put back the same valve body. I am broke and can't afford a new valvebody like the manual says. I did not dissassemble the valvebody when I dropped the tranny.I also switched to Mobil 1 fully synthetic. but I remember filling it up, driving around the block, then I turned it off and filled it up again and that's it. Must have been like 9 quarts. Could temperature really cause this stalling when turning a curve or slowing down? And second gear slaming in sometimes if you tap the gas after slowing down dramatically?

 

Mobil1 ATF is not an approved fluid for your Audi Tiptronic transmission. You may want to put the right ATF in the car. Pentosin is an Audi approved ATF.

 

It sounds like you are done. Sell it and get something that makes you a happier person.

 

Well, thank you so much for your input. Makes sense. I never turned car on while filling from bottom. So, you think it can be short a couple quarts? This can cause downshift problems? I filled the torque converter before installing it, been driving like this for two weeks or so. If this was the problem, I will be releived

 

Enjoy your new Camry, luxury European cars are not for you. No big deal, there not for everyone. That's why we have options.

 

 

Your either have too much or too little fluid. The tip tranny doesn't do too well with other fluid in it like the Mobil 1 ATF. We experimented wtih that at our dealer and it shifted like crap in all gears. The only fluid that seems to work with our gearboxes are the factory fluid or equal that you can get from www.ecstuning.com, www.purems.com or www.germanpartsonline.com
