My car has an automatic transmission.

A transmission rebuild kit will normally include all seals and gaskets as well as other major components that contribute to the overall performance of the transmission. If the part is a wear item or a potential leak source, the rebuilt kit is likely to include it. The rebuild kits purpose is to replace parts that are known to fail in the transmission in order to maintain a long-life of the transmission.
