Transmission Fluid Leaking problems of the 1997 Hyundai Accent

For the pc system problem, I had noticed that the pc valve was leaking oil around it, so I replaced the component on may 12,2000. By December, I noticed that the car had some sort of problem with a noted drop in performance and fuel economy. So I decided, before bringing the car in for maintenance, to visually check the fluids, and wear components. I ended up finding sludge in the engine, created by water in the oil. When Dodge/Hyundai of paramus checked-out the car they told me the problem was a clogged pc system and it was not covered by any warrany, so I paid for the work. For the transmission problem I noticed that it was leaking, and when the dealer in paramus checked-out the problem, they told me that someone had over-torqued the oil pan, blowing out the gasket. They told me that the problem should be warranteed by altman in n. Charleston, since they did the 30k check-up. When I informed altman, they told me that paramus should have done the work as warranteed. So, mike at altman told me I would receive a refund, but I never did, and mike doen't work there anymore, and no one else knows anything. I talked to hyun. Motor amer. Cust. Service, and I am currently waiting for a call back. What I want to know is if either of these is covered by warranty, and if so what then?.
