We got a Mitsubishi FGC30K in our shop and are having transmission issues.

The truck came to us with absolutely no forward or reverse movement. We removed the engine from the unit to inspect the transmission. We removed the valve body from the trans and removed the giant snap ring holding in the clutch packs and found that the first few clutch packs are in great condition showing little to no wear. After putting that back together we disassembled the transmission pump and found major wear.

We replaced the torque converter and transmission pump and got the unit back together. Now that it's together we are not getting any fluid flow or pressure. Everything is spinning properly inside the trans and in the bell housing. The shift solenoid (not sure the correct term) is also operating properly.

We are at a loss - wondering what else could be causing no fluid/pressure. Anyone have input on this or is it time to swap this transmission as a whole?
