Hi! I have a 2005 s4 that has been in some water, flooded car shifts nice at hard or firm acceleration but driving easy it feels like the the torque converter has a shutter and sometimes I get a fiberation. I had the transmission serviced at the dealer, was told the fluid 90.00 a liter, $1500 service and problem still isn't fixed. Any help or suggestions?

 

When I did a trans flush the fluid was only 20.00 a liter...And yes it was the correct fluid

 

You got ripped off. My dealer said that the change is $400 parts and labor.
