There is a known issue with using this oil in the RX-8 transmission.....do a search

wow....

My advice, search and read up on things.

These transmissions are expensive temperamental and its not something you want to do if you don't have all the facts.

Are you certain you added the proper amount? It might be a good idea to double check it.

How in the world do you put that much in? You fill through the fill plug until it starts coming out. Should take about 1.8 quarts.

No we mean that you fill it up until it starts seeping out.

There is no physical way that 4 quarts will fit in that transmission. How did you measure those quarts?
