904 Transmission Stopped Going Into Gear

I will take another look at the pump alignment.

The valve body and governor were filthy when I removed them.

I completely disassembled the valve body and governor, cleaned everything, and reassembled with transmission specific lubricant per the rebuild guide I am using. All valves and check balls moved freely in my finished assemblies.

I like the idea of mods (transgo kit, part throttle kickdown kit, etc..) but because this is my first trans rebuild, my goal is to rebuild this 904 to bone stock for my 225 slant six. Even though those mods are easy, I feel like I need to pull off a stock rebuild successfully before I learn new tricks.

Also, I agree that there is no telling what a previous owner did judging from the incorrect thrust washers, so that's another reason I want to get this trans back to factory specs for starters.
