Directions
2nd clutch: the normal steel plate is .068 in thick, with five steels (062733) and six .070 in frictions (062722). Using the .090 in 062733-228 steel together with OE thickness steels lets you adjust the pack.
Forward clutch: the 041251-082 snap ring adjusts the clearance.
3rd clutch: the normal stack has five internal splined (062724) and five external splined (062725) 1-sided plates, .079 in thick. Using five of the .083 in 062715 external spline plates gains .040 in of clearance.

Nice kit of clearance upgrades
I used this kit to reduce the 3rd clutch clearance on my 2002 Volvo 4T65EV transmission from 0.070" to 0.045", which was a better alternative to shimming with a shaved used external friction. Each of the five frictions will only gain you 0.004", so I don't know how the claim of 0.040" clearance gain is calculated. I already had two thicker 2nd clutch steels, so didn't need the ones in this kit, but they would have been useful if I didn't have them already. The input retainer ring, although thicker, is also narrower than the stock ring and doesn't hold in place in the input housing as firmly, so I stayed with the stock ring.
