Sorry man I forgot to answer you back. There is a thrust washer between the 2 clutch packs but it's a fixed thickness of .063 The one between the pump and front clutch is the only one you want to change thickness on. .150 is a tremendous amount which makes me think you left out either the small metal thrust washer between the input and output shafts or the .063 fiber thrust washer between the clutch packs. Double check to see if they're in their.
