Is that a check ball?
Paging @Greg Ducato
That makes my head hurt.
Can you find your way out?
What year is the trans built for? Is it a factory build I'll look at all data tomorrow.
I'll check tomorrow when I get to workIt's a late 80's case 87-89 and valve body. As far as I know it's a stock valve body.

Like a 4 speedI think you might need a new trans, guy.
