Discard the capacity modulator valve, spring, and end plug. 3. Using the Sonnax reamer and drill jig 76991-TL and plenty of cutting fluid, carefully ream the valve body bore using a T-handle or speed handle. Intermediate Clutch 4. Remove all debris. Intermediate Clutch 1-2 Accumulator 5. To maintain original 1-2 shift, use the yellow replacement spring. D2 For firmer 1-2 shifts, use the pink replacement spring. (The black spring will provide the lightest 1-2 shift, best in lightweight vehicles, Crown Victorias, or applications requiring soft 1-2. The yellow spring will offer a slightly firmer then OEM 1-2 shift, best in full size, vans, or pickups requiring slight improvement or quicker 1-2 shift. The pink spring offers the firmest calibration for quick 1-2, which may be too abrupt for commuting Mustangs or Crown Victorias.) 6. Lubricate the replacement valve, o-rings and end plug. 7.
