When Solenoid SL1 is OFF solenoid modulating pressure will be connected to the port leading to the spring side of the B-1 Lock valve stroking it to the left. SL1 solenoid modulating pressure continues on to the first

land of the B-1 Control valve stroking it to the left connecting line pressure from the manual valve tothe 2nd- B-1 Brake apply circuit Note: The PCM controls the duty cycle of the SL1 solenoid

as it is turned OFF to regulate B-1 brake Apply. The PCM also will turn SL1 on briefly during the 2-3upshift to control the B-1 exhaust by draining solenoid mod pressure, which in turn allows the solenoid modpressure on the front of the B-1 lock valve to stroke the valve to the right connecting the B-1 apply pressure

to the spring side of the B-1 Control valve draining the B-1 brake. Incorrect timing of this application of this solenoid will cause a momentary bind on the 2-3 upshift.

3 way check valve

DIRECTC2 CLUTCH

When Solenoid SL2 is OFF Modulating Pressure will be connected to the port leading to the spring side of the C2 Lock Valve, stroking it to the left and the first land of the C2 exhaust valve. Solenoid Mod.

pressure is not capable of overcoming the spring tension and the line pressure at the spring side of the C2 Exhaustvalve so the valve stays to the left. SL2 pressure is also fed to the first land of the C2 Control valve, which

strokes the valve to the left, connecting line pressure from the 3 way check valve to the C2 Clutch.Note: The PCM controls the duty cycle of the SL2 solenoid as it is turned OFF to regulate C2 clutch Apply.

When the S4 Solenoid is OFF line pressure from the Main reg valve applies the UD/B3 brakethru the 3-4 shift valve.

Summary

When the S4 Solenoid is ON line pressure passes thru the S4 solenoid to the first land of the 3-4 shiftvalve stroking it to the right connecting the line pressure from the manual valve in the D ranges to the

UD/C3 Clutch as it drains the UD/B3 Brake applying 4th gear.

VALVE BODY MAPPING U140/U240E

HOW TO USE THIS MANUAL:

All castings and spacer plates have been numbered so they can be identified in an oil circuit diagram. Example: 319L passage is

located in the Upper valve body (300L series). This passage can now be located in the partial oil circuit diagram shown above. Spacer

plate orifice sizes and locations are also identified in the oil circuit diagram labled Valve body Mapping.
