I took the vehicle to Hendrick Subaru in Feb. 2023 for diagnostics and was told the leak was unserviceable and needed replacement. I was told they detected minor slippage at the time. It is now June 2023 and the dealer is telling me that the transmission is not going to be replaced, but rather resealed and they are now claiming there is no record of it ever slipping and they cannot replicate it. …”
