Hello. Yesterday my mechanic replaced the automatic transmission fluid of my A4 1.8T 2005 with RAVENOL ATF 5/4 hp recommended for replacing the G052 162 A2 Audi. The transmission was working very well before replacing the fluid. Everything seemed to be going well in the road back after this work. After leaving the highway, I noticed that the third speed has slided and entered thereafter. Everything was done in order, except for the speed shifting during the filling of the transmission as explained on all the DIY seen on the Internet, vag-com was used to check the temperature. But I think it misses the liquid despite just over 5 liters we put into the transmission. First gear, second gear, all right, but the third slipped a bit and ends up entering, the fourth and fifth speeds after are correct. In your opinion, what could be the problem?

So, I think is better to listen Audi, and don't touch the transmission. They say that Audi fluid is enough good for the life of the car. The stupid transmission was working so well, the mechanic did not touch any part of de transmission, only change the filter and the gasket. I read in many places it's good to change the transmission fluid, just to extend the life of this. But I just realized that's a mistake. And many have had problems after changing this cursed liquid.

Details on the car would be good. CVT or tip, mileage.

I think it is a myth that fluid changes cause issues. On my only automatic car, an ML320, I have changed it twice. Once at about 100K and about 200K. It has 268K on it now. I think in your case you need to reconsider the fluid you used. Not sure who recommend it as a replacement, but I would not put anything other than Audi tranny fluid in it. ATF's are not equal.

I will try to change it again, even the filter. On an other post, something similar happens and the problem was the filter, almost identical, but the tube was 10mm longuer, causing a similar issue. I have bought the chipper one, Meitersatz brand. I will try to put one from Audi dealer bought with the serial number of the car, and audi fluid instead the Ravenol. But, Ravenol is recommended for my car also, as seen on the net. Thanks for commenting.
