Vehicles with VW/Audi 09A or Jatco JF506E transmissions may exhibit TCC apply and release problems and reduced cooler/lube flow. These complaints can be caused by severe wear of the TCC control plunger valve sleeve. Regulated apply pressure entering the sleeve will be allowed to exhaust without properly stroking the control valve. Sonnax TCC control plunger valve kit 122892-01K restores hydraulic integrity to properly position the control valve. The kit features tightly controlled tolerances and upgraded materials that restore hydraulic control while combatting premature wear.

• Precision sleeve is manufactured from highly wear-resistant aluminum.
• Hardcoat anodized plunger valve resists wear.
