Basil700 Posted January 22, 2009 Author Share Posted January 22, 2009 Thanks for the reply.This old girl I have picked has a 15 speed fuller trans behind the 400 and 44000 Mack backend.The fella I bought it from assures me it came from the factory in this configuration.Barry Quote Link to comment https://www.bigmacktrucks.com/topic/8055-r766-mack/#findComment-29556 Share on other sites More sharing options...
