SECONDARY COMPLAINTS
Poor 2-3 shift feel, 3-2 tie-up
THE CAUSE
Inadequate metering of the 2nd band servo release oil.
CORRECTION
This part combines an orifice with a ball check valve to meter servo release oil. Sonnax Part Summary
Technicians would like to find a way to successfully extend the life of 3-4 clutches, and improve
the 2-3 shift feel. They have been trying, with limited success, since the 700-R4 transmission was
first introduced. Inadequate metering of 2nd gear band servo release oil causes 3-4 clutch failure.
The 3-4 clutch and 2nd gear band are not properly synchronized. Sonnax has now developed a
unique solution that combines an orifice with a ball check valve and solves these problems.
Features & Benefits
Improved design meters servo release oil, reducing 3-4 clutch failure.
Provides sufficient exhaust so that 3-2 downshifts are smooth.
Calibrates 3-4 clutch feed orifice without creating shift concerns
