9、), shall not exceed 72 dBA. In order to verify compliance with this requirement, the transmission shall be tested in all possible drive-by gear ratios and the transmission contributed noise level of each gear ratio shall be measured and recorded. The average contributed noise level, plus two standar
10、d deviations, shall not exceed 72.0 dBA for each of the gear ratios measured during the drive-by test.

These ABR features exist solely for the benefit of Navistar assembly plants and customers who can order options provided by the transmission supplier. A full list of p
23、ossible ABR features, as well as the Key Critical Characteristics (KCC) within those ABR features is detailed herein. 5.1.1.1 Base Transmission Each base transmission released is part of a family. A family can consist of any number of transmission feature codes. The definition of a family shall be t
24、ransmissions that share the same basic design and external dimensions. A drawing will be generated for each family, detailing the ABR categories applicable to the family. There are no KCCs on this ABR category. However, any changes to the Base Transmission from the supplier affecting “form, fit, or
25、function” such as transmission size impacts or transmission mount changes must be approved by Navistar through the SREA Process. The specific distance from front of case to PTO bolt pattern (433 mm for Tremec/446.4 mm for Eaton) must be maintained for all product. A subsection of this ABR will be ap
26、plicable to AMTs and DCTs only. Controls CAN Communication Rate will define the baud rate (250k vs. 500k) at which the J1939 network communicates at. 5.1.1.2 Shift Controls Applicable to manual transmissions only. Some suppliers have the ability to have the shifter tower in a forward, or center/stan
27、dard position. Some transmission families may also have full lower stub levers installed by the transmission supplier and shipped to Navistar plants in that configuration. Whether the shift tower is shipped to our factory installed on the transmission or shipped in separately, the shift tower will h
28、ave a released Navistar print that controls the shift lever length and bend points. The mating surface of the transmission to the shift bar housing is a supplier controlled mating surface. There are no KCCs for this ABR category. 5.1.1.3 Output Shaft Speed Sensor This ABR category defines the number
29、 and type of Output Shaft Speed Sensors to be installed by the transmission supplier prior to delivery to Navistar. The sensor itself is controlled by the transmission supplier.
