Now that the rear planetary carrier is installed, we can start building up the core of the transmission. Let’s start stacking clutches!
These two snap-rings hold the pressure plate in place. When it receives fluid pressure, the low/reverse piston underneath this clutch-pack will press upward against the pressure plate, clamping the frictions and steels together in between, locking the front planetary carrier to the case.
So between those two clutch-packs is the pressure plate, which stays stationary. The low/reverse piston presses its clutch against the pressure plate from below, and the 2-4 piston pushes from up top.
(Eh, “top” and “bottom” are relative terms here. I have this transmission mounted on a stand with the bellhousing facing up. But once it’s back in the vehicle, these are going to be sideways motions.)
The front planetary’s teeth are at the bottom (or rear, I guess I should say), and they must pass by the 2-4 clutch and engage with the L/R clutch. So we wiggle the planetary back and forth to line up the teeth and work it deeper into the case.
Next: the input drum! 41TE Assembly, Pt. III

Wild! I’ve actually never looked at pix of transmission guts before. That looks SO scary haha

That’s why these posts are coming in bite-sized pieces! The whole thing would be just too overwhelming, I think.
