Dajain Posted January 22, 2022 Share Posted January 22, 2022 I have a 1975 Mack firetruck I was going to use for a project but things might be changing. Still haven't convinced myself that I'll never get to it. haha. The truck has about 32k miles on it The motor is the Mack ENTD-865 turbo diesel. It runs perfect and purrs like a kitten The Transmission is the Allison HT-740D Automatic. This will not shift out of 1st gear. I've never had a chance to troubleshoot but I was going to look for a 4x4 transmission anyways. One thing I thought was maybe there is a safety to protect the water pump from over speeding and that is why it won't shift? Never really looked at it. !st forward and reverse both work fine. The firefighting components are kaput. Don't even figure that as any part of the value. I have the original Mack Service Manual from the factory with it also but I have no title. Just curious what a fair price would be for this? From what I have read, these motors are impressive for performance and torque and that is why I was thinking of using it for my project . What would be a fair price for a low mileage motor in a rolling chassis? Quote Link to comment Share on other sites More sharing options...
