Anybody ever rebuild a sm465? Mine makes a horrendous noise when I let off the gas and it transitions from acceleration to engine braking. As long as their is pressure on the gears whether accelerating or engine braking it doesn't make noise. Also if I'm coasting in neutral or in gear with the clutch pushed in it makes a loud clicking noise. Took the top cover off, I see wear on the reverse idler gear, the 1/2/Reverse slider, and the counter shaft reverse gear. But I doubt that a big deal...
