Hotshotrucking

Just purchased the Granite tri-axle with the Mdrive, MP7 and will give you feedback as we go. I did read something about if the motor shuts off and the truck is moving it does damage to trany? Wondering if this is tru in neutral being towed? This truck will cut its teeth in the paver running in neutral with pto engaged and bed going up and down. Any advice would be great.

I'm interested in finding out more about the MDrive Mack Transmission? How it works in a dump truck, off road, paving, milling. I have an Allison Auto in one of my new trucks and love it.

I also switched back from synthetic because I felt they both gave the same protection. Reason for the leaks from what I heard was synthetic cleaned all the old gunk which built up around all the gaskets which caused the leaks. Even though they are the same 15W40 viscosity the synthetic feels thinner.
