Only have one question, I removed the transmission from my vehicle listed above and noticed it was not leaking from external seal. So it's coming out of front pump seal. Is that something I need to take to a expert or can I myself change it?
Do you

Can you get a picture of where the leak is coming from? When you say it was not leaking externally but it is coming from the pump seal, I am just not sure which seal you are talking about. The front pump seal may mean something different to you and I. Are you saying the seal that is around the pump or the one that is around the reaction shaft/input shaft?

Take a look at the picture. Then if you can snap a pic of where yours is leaking from would really help. Thanks

So the leak is coming down from the outer part. Where you see the oil is from where it's comes out. I don't know a better way to explain it, sorry lol.

That is great. Just what we needed. You would need to remove the oil pump and replace the seal that is around it and the gasket between the pump and case. I attached the info on how to do this. You do need slide hammers to get it out so if you don't have the tools, you can rent them or it may be easier to just take it to a transmission shop. The fact that it is already out, I am sure it will not be much to have it done.

The trickiest thing is the installation. You should not need to change the end-play but we should check it. Again the process is attached.
