TRANSGO 6T40-PDP-OS Pulse Damper Piston Repair Instruction Manual
Even a little wiggle has a significant effect on solenoid pressure to the controlling clutch regulator valves. Flare shifts, harsh shifts or erratic shifts are a result of poor clutch control. A worn damper must be corrected to provide a smooth solenoid signal to the clutch regulator it serves. The smoother the solenoid signal, the more consistent and cleaner the shifts will be.

Step 2. Install small end of lineup pin into the damper hole to be reamed.
Step 3. Place jig with bushing over lineup pin and rotate jig until two bolt holes lineup in jig slots. Always use the thick aluminum washers on both sides to protect VB and Jig. Tighten down jig with supplied bolts, thick washers and wing nuts. Remove lineup pin and its ready to ream.
Step 4. Use lots of WD-40 and low speed on your favorite portable drill and let the reamer do the cutting until it bottoms in the bore. Don’t force the reamer! Bore finish and Reamer life require a slow inward movement and lots of WD 40. Keep an extra set of 6T40-PDP-OS dampers on hand. You’ll need them for the next job!
