How do I adjust the idle speed on my Ram diesel? The idle speed seems too high. First, trace the accelerator linkage to the connection on the fuel pump. With the ENGINE OFF have someone floor the accelerator and watch the fuel arm move. The best position I can describe is that it is under […]

24V Transmission Band Adjustment

One of the most frequent questions I get on the Cummins powered Dodge trucks is transmission related. The Dodge automatic tranny is very robust and does what it was intended to do very well. But given the reputation for massive torque that the Cummins engine provides, many times the transmission is asked to do far […]
