    Even a little wear has an effect on solenoid pressure to the controlling clutch regulator valves. Flare, harsh and erratic shifts all are a result of poor clutch control. A worn dampener bore 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 and TCC will be. TransGo oversized accumulators include matching calibrated springs to maintain the same function as OE and repair higher mileage units with extreme bore wear.
