[Ventura HiWay]

I am looking for a diagram or drawing of the Transmission Valve Body that shows how many & where the check balls (under the seperator plate) should be. Can any body help with where I can find this info?

I need to pull the Valve body and plan to work on it this w/e. I was told by a Trans tech that sometimes the check balls between the valve body & the separator plate can deteriorate & and block a passage.

Thanks
