Pressure Plates

PATC Sells Transmission Pressure Plates, Billet Pressure Plate, Heavy Duty Cast Pressure Plates from TCS, Sonnax and Alto Products.

The 727 / 46RE / 47RE / 48RE Direct Clutch Backing Plate is made for 15 return springs.

GM 6L80/6L90 1-2-3-4 pistons commonly crack due to cantilevered stress on the cast material. The OE part has been through several revisions in an attempt to correct this, but all OE versions are still chronically known to crack. Sonnax 1-2-3-4 piston 104984-01 is made from stronger, billet aluminum and has superior design refinements that add additional strength to prevent breakage and deliver maximum performance.

727 / 46RE / 47RE / 48RE Reinforced Front Clutch Piston

Sonnax #22965A-01, OE Part No: 02464651AE, 02464651AB, 02464651AD, 02464651

OE cast front (direct) clutch pistons in listed Chrysler units crack and break , resulting in direct clutch failure. Sonnax reinforced front clutch piston 22965A-01 is made of cast aluminum and specially designed to guard against failure with additional webbing that reinforces weak areas of the piston.

NOTE:

The Sonnax piston is a direct replacement for OE part numbers 02464651AB, 02464651AD and 02464651AE used in ’98-later 46RE, 47RE and 48RE units. Can also be used as a replacement for OE part number 02464651 in A727, as well as ’97-earlier 46RH/RE and 47RH/RE units when used in conjunction with thicker steels to compensate for the .020″ thinner piston.
