Operation - The shift pressure (p-S) is determines by the sh ift pressure regulating solenoid valve (Y3/6y2) and
the shift pressure regulating valve (24). See Fig. 68
. In addition, pressure from the multiple-disc clutch K2 (p-
K2) is also present at the annular surface (24a) of the sh ift pressure regulating valve (24). This reduces the shift
pressure in 2nd gear.

Operation - The working pressure (p-A) is regulated at th e working pressure regulating valve (22) depending
on the load (modulating pressure (p-Mod)) a nd depending on the gear (p-K1, p-K2). See Fig. 70
. A minimum
level (basic pressure) is adjusted by the spring in the working pressure regulating valve (22).
