Input Sun Gear still in the planet upon disassembly....If you have a Early or Mid-Year forward sprag assembly.

OK. The output shaft is out, Time to pull the Input planet, Carrier & Sun shell. Grab the Sun shell from the inside 180 degrees apart & pull up.
This will expose the Center Support, Low/Reverse Sprag, & Reaction Sun Gear.
Remove Reaction Sun Gear.

On stock unit's There will be a plastic thrust washer on the low/reverse sprag race, The outlined arrow is pointing at the race, Place this thrust with the sun shell.

Remove the snap ring holding the Center Support (Yellow arrow).

Re-insert the output shaft, One good (Square) hit with a 3 pound sledge will separate the Center Support, Reaction planet, Carrier, & Low/reverse clutch stack, Pull the whole assembly from the top.

Red arrow is the Anti-Clunk spring, Might have a "Case Saver" heavy T looking piece.
