Transmission Failure Problems of Audi A8

I own a 2008 Audi A8 with about 48200 miles. It is great vehicle but having problems with transmission during driving. Under load it will go in fail safe mode around 4,5,6 gears. It is causing dangerous situations as car starts stopping suddenly and causing driver momentarily loose control of a vehicle. This iissue was brought up to a Audi but they said it is past warranty. By doing an independent research, it was found that there is one single teflon seal controlling fluid pressure for a clutch e. That seal wears out prematurely causing fluid to loose pressure and failing safe transmission. In order to repair this issue seal needs to be replaced with aftermarket one. Information about it was obtained from zf transmission service bulletin and is available online. Zf manufacturing knows about this and rebuilding this transmission. When fluid pressure is lost it causing transmission fail safe in order to prevent completely being damaged. All fail said occurs when vehicles show being driven. Please investigate this problem because it creates a safety hazard. The attached pictures are screenshots from scanning transmission errors. Also, there is a copy of zf technical bulletin manual describing cause of a clutch e. It seems to be designing flow with this transmission. Thank you.
