Ive done the 4l60e servo swap, the question was is the upgraded servo in the 4l80e worth doing
It's actually not needed in the Th400 or 4L80-E. They are bigger servos and wider bands already so they hold tighter as is. About the only thing you could do is maybe a shift kit that might open up an orfice in the seperater plate that would allow more fluid pressure for maybe a quicker apply of the servo. Honestly, not so sure it would work anyway in a 4L80-E being it's computer controlled and solenoid shifted, but it could and does work in the Th400 for certain.
