Lastly, the drop-in USA-made hardened steel clutch select valves greatly help prevent the valves from sticking in their bores. Dec 29, 2022 · The valve body (Figure 2) had a lower valve body section added to the channel plate. The solenoid switch valve remained the same. The interesting thing about this is that the RFE has a TCC regulator valve that is in charge of controlling the amount of TCC apply pressure that gets to the apply side of the clutch, but this valve only functions as a regulator valve during partial apply. There is minimal valve-to-bore sealing at the line pressure to converter feed circuit, which allows critical apply fluid to leak past the valve spool and directly to exhaust/sump. These changes included adding an auxiliary valve body, adding a dedicated TCC control solenoid, and changing the TCC regulator valve.
