Howdy Paul! Well I was/am familiar with driving diesels but they all had gears I shifted using a clutch. None of this automatic business I have now. Our home here in NSL is on a 13% grade and it's just over a mile to get to the bottom. Engine brakes are prohibited but I'm not sure if they meant it to be only for commercial vehicles? I started out in 1st gear but it jumped to 2nd rather quickly as it was supposed to because of the high RPM's. I will definitely try using the downshifting in the future though for passing. But I hate to pull out into the 90 MPH traffic even with the 4-way flashers on.

The engine brake is heavily muffled, don't be afraid to use it. Much quieter than a Jake Brake. Use that down shift going down steep grades too, that in combination with the engine brake will really save the regular brakes from over heating and premature wear.

Most communities that do not allow engine braking are referring to the Jacobs (Jake) braking system, which pops exhaust valves on compression and makes that Jake brake noise. The Berkshire closes turbo vanes, basically blocking the exhaust, for engine braking. Leave the engine brake on, it is not noisy, communities banning exhaust brakes would not know you are using it (they are concerned about noise), it is safer, however, an actual Jacobs braking system is much more powerful.
