6T40 / 6T40 / 6T41 / 6T45 / 6T45 / 6T46 / 6T50 / 6T50 / 6T51 3-5-R Drum Saver Kit, Sonnax 144555K.

The 3-5-R waved plate in GM Gen. 1 and 2 6T40/45/50 units commonly fails and breaks into pieces, resulting in code P0776, harsh and flare shifts, or complete loss of 3-5-R. In spite the OEM attempted to prevent this problem by issuing an updated (shot-peen) plate, it continues to fail in some units, damaging the drum housing splines. The teeth on the OE plate are high-stress points that cannot stand up to long-term fatigue. Even plates that have not been fractured can have microfractures at the tooth corners, putting them at risk of failure.

The Sonnax 3-5-R drum saver kit (144555K) is an effective and affordable way to guard against failures and costly comebacks. Sonnax now designs the wave plate without teeth to eliminate most stress points. The custom cupped steel plate on the drum provides optimal protection against plate and drum failure.

The drum saver kit can also be used for salvaging a damaged drum, saving you the time and price of building a new one. With no teeth to hang up on damaged drum splines. The Sonnax waved plate can ride in this area without hanging up or interfering with proper clutch pack travel.

  • Shot-peened, toothless waved plate is stronger and more durable than any other OE or aftermarket plate
  • Custom, billet cupped steel plate aligns waved plate on drum and sets correct clutch clearance
  • Quickly and easily restores normal 3-5-R operation to damaged drums

  • Cupped Steel Plate
