Part No: RTK-1024Components:6 pcs GPZ195 Friction Plates (0.071”)6 pcs 511642 Steel Reaction Plates (0.098”)1 pc R699662 Steel Reaction Plate (0.079”)Installation Instructions1. Install the C4 piston with orifice at 12 o’clock position. Lube seal surface and install evenly.2. Install in the following order (*TIP: Remove or do not install Piston Return Springs at this time):0.079” R699662 Steel Reaction Plate0.098” 511642 Steel Reaction Plate0.071” GPZ195 Friction Plate0.098” 511642 Steel Reaction Plate0.071” GPZ195 Friction Plate0.098” 511642 Steel Reaction Plate0.071” GPZ195 Friction Plate0.098” 511642 Steel Reaction Plate0.071” GPZ195 Friction Plate0.098” 511642 Steel Reaction Plate0.071” GPZ195 Friction Plate0.098” 511642 Steel Reaction Plate0.071” GPZ195 Friction PlateOE Backing PlateSnap Ring3. Check clutch clearance between C4 backing plate and top friction plate using a feeler gauge. *Recommended clearance range: 0.040”-0.060”.4. Remove friction and steel components and saturate friction plates in either manufacturerspecified ATF or comparable synthetic ATF.5. Confirm C4 piston orifice is located at the 12 o’clock position.6. If removed in step 2, install piston return spring assembly.7. Install (1) 0.079” and (1) 0.098” steel reaction plate with slots centered over C4 piston orifice.8. Install P1 planetary and P2 ring gear assembly.9. Using the steel slots as a guide, align the friction plate slots during assembly.10. Align slots in steel reaction plates, ensuring slots do not block or partially block the C4 piston orifice. Note: You may need to index or flip the steel reaction plate over to accurately locate and center the slot at 12 o’clock.11. Install the C4 backing plate and snap ring.
