My a6 you really have to sink to the floor to get it to drive but when in reverse is 100 percent normal,could this simply be a torque convertor ? or a whole tranny ,thanks,tyler

 

The TC would behave the same in both forward and reverse. You probably have a problem with a solenoid valve or an internal clutch. Hope for the solenoid. It can usually be changed with the tranny in the car.

 

Okay ! how do i check solenoid ? and i wouldn't think so much the clutches as the car only has 142k

 

Have your car scanned with a VAG-COM. If you know someone with access to one it can tell you a lot, particularly if you can run some tests while driving. There are a large number of transmission diagnostics. If your Check Engine light is on there will definitely be codes but even if it is not the VAG-COM can tell you which solenoid(s) are engaged and the input and output shaft speeds of the transmission.
