904 Transmission Stopped Going Into Gear

So far. Clutch clearance is critical and different manufacturers make different thickness fibers. Count the clutches. Thin smooths are forward and waffled are direct. Might be too burnt to identify. And always check endplay before you remove the pump so you have some idea how big to go oversize thrust washers. Too lose and the direct drum wobbles. And grease the center pump gear on center.

I tried to check the endplay with a magnetic dial indicator reading on the input shaft before I took anything apart. I could not make the shaft move in or out by hand (barely moved the needle). Maybe everything is cooked together in the clutch disks?

I plan on giving everything a nice coat of transmission assembly grease, especially the gears in the pump.
