Re: Downshifting Suggestions
Yes, that should be it. You turn it on while going down hill to save your brakes. Some are called exhaust brake, Pac brake, Jacob brake and Retarder brake.
The exhaust and Pac brakes are the same works off the exhaust to slow the coach down and at the same time it shifts down. Jacob and retarder brakes work directly off the transmission.
Most of your bigger engines have Jake brakes. Some like Foretravel had Retarder brakes.
