6T70-ACCM-G2

Drop-in fix for accumulator bore wear causing 4-5-6 clutch failures and shift complaints. TransGo 4-5-6 Accumulator Piston Kit for General Motors 6T70, 6T75 and 6T80 GEN2 transmissions from 2013-on. The 4-5-6 accumulator piston plays a vital role in the application of the 4-5-6 clutch. When wear occurs in the piston bore, it creates a loss of 4-5-6 clutch apply pressure. The loss of apply pressure leads to clutch slippage which can cause harsh or delayed shifts, shift flares, ratio codes and clutch failure. The reengineered piston has two strategically placed O-rings to prevent further piston-to-bore contact/wear, in addition to renewing the 4-5-6 accumulator circuit integrity and salvaging a worn valve body. Corrects, Prevents, Reduces: Slips in 4th, 5th or 6th gears Burnt 4-5-6 clutches Dual sealing design prevents piston-to-bore contact/wear Salvages a worn valve body Solenoid performance and or ratio codes
