Custom Fire Apparatus, Inc. <br />6th 0.67:1 (if applicable) <br />Rev 5.55:1 <br />TRANSMISSION MODE PROGRAMMING <br />The transmission, upon start-up, will select a six (6) speed operation without the need to press the mode <br />button. The transmission programming shall only include S 1 performance shift schedules. The mode <br />button shall not include a secondary economy shift schedule. <br />TRANSMISSION FEATURE PROGRAMMING <br />The Allison Gen V/VI-E transmission EVS group package number 127 shall contain the 198 vocational <br />package in consideration of the duty of this apparatus as a pumper. This package shall incorporate an <br />automatic neutral with selector override. This feature commands the transmission to neutral when the <br />park brake is applied, regardless of drive range requested on the shift selector. This requires re -selecting <br />drive range to shift out of neutral for the override. <br />This package shall be coupled with the use of a split shaft PTO and incorporate pumping circuits. These <br />circuits shall be used allowing the vehicle to operate in the fourth range lockup while operating the pump <br />mode due to the 1 to 1 ratio through the transmission, therefore the output speed of the engine is the input <br />speed to the pump. The pump output can be easily calculated by using this input speed and the drive <br />ratio of the pump itself to rate the gallons of water the pump can provide. <br />A transmission interface connector shall be provided in the cab. This package shall contain the following <br />input/output circuits to the transmission control module. The Gen V/VI-E transmission shall include <br />prognostic diagnostic capabilities. These capabilities shall include the monitoring of the fluid life, filter <br />change indication, and transmission clutch maintenance. <br />Function ID Description Wire assi ng ment <br />Inputs <br />C PTO Request 142 <br />J Fire Truck Pump Mode (4th Lockup) 122 / 123 <br />Outputs <br />C Range Indicator 145 (4th) <br />G PTO Enable Output 130 <br />Signal Return 103 <br />TRANSMISSION SHIFT SELECTOR <br />An Allison pressure sensitive range selector touch pad shall be provided and located to the right of the <br />driver within clear view and easy reach. The shift selector shall have a graphical Vacuum Florescent <br />Display (VFD) capable of displaying two lines of text. The shift selector shall provide mode indication <br />and a prognostic indicator (wrench symbol) on the digital display. The prognostics monitor various <br />operating parameters and shall alert you when a specific maintenance function is required. <br />ELECTRONIC TRANSMISSION OIL LEVEL INDICATOR <br />The transmission fluid shall be monitored electronically and shall send a signal to activate a warning in <br />the instrument panel when levels fall below normal. <br />TRANSMISSION PRE -SELECT WITH AUXILIARY BRAKE <br />07/26/22 <br />-21- <br />
