Help me put valve body back together.

I got pretty much everything down but all of the instructions I see say that I should have 8 rubber check balls (I have them) and 1 steel check ball (I have something that resembles a check ball). Can you guys tell me if this is the 9th check ball for the upper portion and how does it get insterted? When I was taking mine apart it kind of fell out so Im not sure.

Looks like trans was apart before because of aftermarket gasket. That does looklike that is the steel electronic pressure control check ball (EPC) just maybe aftermarket too. Should work the same probably easier to install without it popping out with having the points. The spring goes in the tranny the pointy needle part points into the gasket and the stubby shaft part goes into the spring. These will go in the hole left of the solenoid pack hole between the R and the A on the gasket everything else looks good.

Are the other check balls rubber or plastic? Plastic would mean they are aftermarket too. Factory ones are rubber. If plastic I would recomend getting the factory rubber ones the plastic ones are known to cause sealing issues.

they seem to be hard plastic as I have tried and tried to squeeze them but they are hard plastic as so are the lower valve body check balls. I guess I need to stop by the dealer but just not sure if I should get the factory steel check ball and spring or stick with this one. What kind of symptoms would I be experiencing if this plastic check balls are no good?

I believe they can cause delayed shifting out of park to reverse and drive and slipping like conditions also especialy reverse. A smaller EPC ball or worn one will affect line pressures.

Well my symptoms were as follows: reverse worked perfect but when I put it in Drive it would take up to 2500 rpm's before it would start moving forward.

That looks like the EPC spring and check that Transgo uses. Checkballs look like viton checkballs. You can use vaseline or trans gell to hold them in place if you have some.

with my transmission not working in forward gears until about 2500 rpms. Do you think I should go back to the factory rubber check balls, well except this metal one with the spring?

Did you check your feed bolts? Is that why you took the vb off?

Yeah I took it apart to make sure nothing was jammed up and feedbolts were good. I "muscle tested" them yesterday and they seem to be tight enough but today I will put on the torque wrench to them. The one I have is 1/2 in drive and I didnt have any 13mm 1/2in drive sockets.
