ABSTRACT:
An auxiliary pressure system is described for a hydraulic activated automotive automatic transmission having a hydraulic fluid reservoir and a line pressure circuit. The system includes an automatic transmission hydraulic fluid connector line having an intake end configured for attachment to a hydraulic fluid reservoir. A pressurization device is connected to the automatic transmission hydraulic fluid connector line, configured and operable to receive hydraulic fluid from the hydraulic fluid reservoir and place such hydraulic fluid under positive pressure sufficient to actuate the automatic transmission. A pressure delivery line including a fitting configured for connection to the line pressure circuit of the automatic transmission, is connected to the pressurization device to deliver hydraulic fluid under positive pressure from the pressurization device to the line pressure circuit and thereby provide operating hydraulic pressure to the transmission for normal operation.
