Before the Big Pull I decided to remove Pan , All Nice and Clean Filtered oil a couple of times no metal , Removed Valve body and found a steel rod holding one of the Accumalators open ???????? what is the purpose of that?????? Another Question How do you know when a Manual Valve Body is past it ??????? Thanx

Blocking the accumulator makes the 1-2 shift firmer. I believe all manual valve bodies either come with a blocker rod or have the ports blocked internally. Don't understand your question about the manual valve body being "past it"?????

Before you yank the trans why not do a simple air pressure check to find out what's not working? If their all working it's likely a valve body issue in which case the trans. wouldn't need to be removed. When you inject air to each clutch pack you should hear them engage and see them move a little bit. Injecting air to the band servo's will make them extend and clamp the band down. If by the test you find one of the components not working you'll know exactly what to concentrate on when you pull it apart.

BTW: wear a full face shield and safety glasses when doing the test cause ATF will probably spray back at you when you inject air at each port

Here's a PDF file showing where to inject air (30 psi) to engage all the components
