B1R exhaust valve
▶
The B1R exhaust valve is a two position
spring loaded valve located in the
transmission case directly adjacent to the
front servo. It permits the servo release oil to
be rapidly exhausted into the transmission
case during application of the front band
(B1). This prevents the needto force the oil
back from the front servo through the valve
body and through the 3-4 shift valve. The
spring positions the valve to prevent oil
entering the release area of the servo until
the B1R circuit oil pressure reaches
approximately 100 kPa.
