It looks like you can get just the seal as this most likely the issue, but you will want to make sure this is where it is coming from because you have to remove the transmission in order to replace it. Unfortunately, Alldata does not have a specific procedure on how to replace this seal but you have to remove the flex-plate which you have to remove the transmission to get to.
Here is the procedure to remove the transmission. Once this is out, you will see the flex plate and the seal is just behind this.
Let me know if you need more information but again, this is a lot of work so we need to make sure this is it. Doing the dye test will confirm it is coming from there before you disassemble. Thanks
