A prime example of this is the Reverse Switch category there are only two possibilities, does the supplier install the switch, which is supplier controlled, or not install the switch. Dimensions of
23、 the switch itself are controlled by supplier. 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 possible ABR features, as well as the Key Critical Characteristics (KCC) within those A
24、BR 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 transmissions that share the same basic design and external dimensions. A drawing will
25、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 function” such as transmission size impacts or transmission mount changes must be appr
26、oved 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. 5.1.1.2 Shift Controls Applicable to manual transmissions only. Some suppliers have the ability to have the shifter tower
27、 in a forward, or center/standard 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 separ
28、ately, the shift tower will have 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. A subsection of this ABR will be applicab
29、le to AMTs and DCTs only. Controls CAN Communication Rate will define the baud rate (250k vs. 500k) at which the J1939 network communicates at. 5.1.1.3 Output Shaft Speed Sensor This ABR category defines the number and type of Output Shaft Speed Sensors to be installed by the transmission supplier p
30、rior to delivery to Navistar. The sensor itself is controlled by the transmission supplier. There are no KCCs for this ABR category. However, any changes to the Output Shaft Speed Sensor from the supplier affecting “form, fit, or function” must be approved by Navistar through the SREA Process. 5.1.1
31、.4 Reverse Switch This ABR category defines if a Reverse Switch is installed by the transmission supplier prior to delivery to Navistar. The switch itself is controlled by the transmission supplier. There are no KCCs for this ABR category. However, any changes to the Reverse Switch from the supplier
32、 affecting “form, fit, or function” must be approved by Navistar through the SREA Process. 5.1.1.5 Neutral Start Switch This ABR category defines if a Neutral Start Switch is installed by the transmission supplier prior to delivery to Navistar. The switch itself is controlled by the transmission sup
33、plier. There are no KCCs for this ABR category.
