How thick is your backing plate (above the clutches)?
I prefer to always use the thick OEM apply plate (0.223) below the clutches, but a variety of backing plates are available from GM and aftermarket for the purpose of setting the clearance.
I have 0.129, 0.157 and 0.194; others are probably available too. Another trick is to use a thinner snap ring.

Here are the thicknesses and part numbers from the ATSG Update Manual for the backing plates:
24217450 = 0.144
24217453 = 0.165
24212460 = 0.194 (I think is is stock for 6-plate 4L60E)
24217516 = 0.219
24217517 = 0.241
The 0.129 I have is aftermarket:

I hope that helps.
