The transmission started slipping in 3rd gear as if it had gone into neutral.

Transmission after removal from the truck

Getting the transmission out is half the job!

Torn down

Initial tear down.

Broken sunshell

This problem was immediately obvious! The splines from the mating part were still engaging in the edge of the shell though, so it hadn't actually let go yet.

Burned 2-3 clutch pack

This was the direct problem. The clutch material was burned and mostly worn off.

Good clutches

All other clutches in the system were still in good condition.

Disassembling clutch pack

I disassembled all the clutch packs for thorough cleaning and inspection.

Planetary gears

All the gears were in good condition, end play in spec for the spiders.

Reassembling clutch drum

Reassembling the input drum.

Installing the reverse clutch

Reinstalling the reverse clutch. This is the only one you can't really do with regular clamps.

Bushings

All bushings replaced.

Final assembly

All parts ready for re-assembly.

Input drum installed

All parts of the transmission installed. End play checked, right in the middle of the spec.
