We test drove a 2000 CC Magna with Cat C10
One thing I was surprised at was the lack of aggressiveness of the Jake brake. When on high (setting three), the transmission would downshift to 4th and some braking would occur. On setting 1 or 2 I could tell little affect on braking. Your thoughts?
I was told the Cat/Allison could be re-programed to downshift the tranny to 3ed on high, setting three, which would also result in some change in setting 1 and 2. I am trying to read up on Jake brakes and understand the relationship between engine and transmission. Any help??
Finally, the engine has 37,000 miles and they are going to do a valve adjustment and engine service this week. Will the valve adjustment make any difference in how the Jake performs??
Thank you for your help.
