700R4 Leaking after new front seal installed. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

The 700R4 is still leaking from behind the TC after I installed it the 85 in December, I put a new front seal in it then. I am getting ready to pull it out and put it into my 79.

What should I look for when I pull it? I have read that there is a bushing on the front shaft that wears out or the pump housings can crack and leak.

Are these the type of things I can do myself or will I need to bring it to a tranny shop?

Trans works great, it just leaks when it's left sitting for a while.
