Allison DOC review

Allison DOC is the factory tool for Allison automatic transmissions, which are common in refuse, transit, school bus and vocational trucks. Allison says the DOC Subscription Service lets users diagnose, service and reprogram its electronically controlled transmissions and propulsion systems. The product line has three parts: Allison DOC Premium for 1000, 2000, 3000 and 4000 Series, TC10 and off-highway CEC5, CEC3, CEC2 and CEC1 controls; a Premium edition for H 40/50 EP and eGen Flex electrified systems; and Allison DOC Fleets for 4th to 6th generation TCMs, aimed at in-house fleet maintenance. Every product needs its own time-based subscription license, sold through the Allison DOC Web Store. The software is RP1210C compliant, so a shop can reuse the adapter it uses for Detroit or Bendix software. As a transmission-only tool, it complements rather than replaces an all-makes scanner.
