The 4-3 downshift is fairly active on a 4.3L 700. A spring change in the Valve Body can fix this if annoying.

Some 4.3L 700's have a small "554" 2nd piston, The 2-4 band can burn-up if used behind a 350.
Use a standard V8 "553" or Vette "093" 2nd piston.
How do you tell if you have this small piston? Take the trans apart? I don't think I'll be doing that until it stops working! Thanks for the info.
