Description
 
Features
  • Vehicles with a 200-4R 700-R4 4L60-E transmission can experience 1-2 light throttle abrupt or "bang" shifts, especially when using the "093" Corvette or "553" 2nd apply servo pistons. The current industry solution is to make the servo piston apply diameter smaller. However, this limits the 2-4 band life. This shift problem can occur due to sleeve wear allowing torque signal and/or accumulator pressure leakage, or when the accumulator valve is too large for the application, resulting in too much pressure on the 2-4 band. This valve train has multiple OEM size variations, including B, A, N, M, L, K, and F. The size variations are clearly stamped with the letter on the aluminum sleeve. Most vehicles, depending upon the transmission/engine combination, can use either the M, L, or K version. However, these are not available unless scavenged from other valve bodies. Sonnax has designed three replacement accumulator valve train assemblies: 77777M-K for the M (.341" valve diameter); 77777L-K for the L (.330" valve diameter); and 77777K-K for the K (.315" valve diameter).
