After doing my 25K service, the local Subaru dealership forgot to tighten my transmission drain bolt. Around 2 weeks later I noticed a puddle of transmission fluid in my garage. The dealership flat bedded the car to the shop and found the drain bolt was only finger tight and I lost 1 to 2 quarts of fluid. Now I am at 28k and my clutch is slipping. I am hoping it will be covered under warranty. I am not sure if running low on transmission oil would cause transmission/clutch slippage but that is what I am experiencing. The car is all stock with zero modifications. I am worried that they will say I beat on the car and make me pay $1,000 to $1,500 to replace the clutch. If that is the case can I have the dealer install a better clutch?
