Effective April 1985 (Julian Date 091 - Figure 1) the spring was eliminated from the throttle lever and bracket assembly (Figure 2, item 50). This change was made to reduce throttle pedal effort. All Service Replacement Transmission Assembly (SRTA) models also have had the spring removed.
Do not install a throttle valve lever return spring on any THM 440-T4 that does not have one. When servicing a THM 440-T4, the spring can be eliminated on any 1984-1985 model to reduce throttle pedal effort.
