Symptoms: Burnt bands Harsh shifts Flare shifts Shift concerns Cause: Worn components allow critical EPC or regulated pressure to cross leak to adjacent hydraulic circuits or to exhaust uncontrollably to the sump. This misapplication or loss of pressurized fluid wreaks havoc with the delicate balance of forces which position the brake control valve for optimal shift timing. Correction: This Sonnax kit eliminates cross leaks caused by wear and retains hydraulic pressure in the critical circuits while pressure loss to the sump is eliminated. Pressure exhaust to the sump is restricted and controlled at the OE V-notch. Required tool: F-147741-TL28
