Valve Body






The 42LE has a cast aluminum valve body that uses five valves to control five transaxle clutches and the torque converter clutch. It also directs pressurized fluid for lubrication. The oil pump is the source of pressurized fluid for the valve body and solenoid assembly. The pump is a positive displacement, gear and crescent type pump. It is driven by the engine through the torque converter hub.

The valve body has two major functions:
- Control line pressure and TCC pressure
- Direct fluid to the clutches, torque converter, lubrication system and the solenoids by means of the manual and switch valves

Fluid for the pump is drawn through the transaxle filter, through the valve body housing and into the pump. The pump pressurizes the fluid and sends it back through the valve body to the regulator valve. The valve body uses five valves along with four solenoids in the solenoid assembly to provide control of the transaxle through all of its gear ranges. They perform all functions needed to operate the transaxle for each of its gear ranges. Another unique feature of the 42LE valve body is that the solenoid assembly and the Transmission Range Sensor (TRS) are attached to the valve body and are inside the transaxle case. This helps to reduce the noise level and the chance that these components will be contaminated by environmental factors.
