Avoiding the automatic transmission fluid levels pitfalls
Checking the fluid level in a manual transmission is typically a fairly straightforward process: remove the fill plug, stick your finger in and see how close the fluid level is to the bottom of the fill hole. To be sure, the transmission specifications may indicate distinct fill levels or temperatures at which the level should

Even the best-maintained transmission jacks occasionally give mechanics trouble. Knowing the potential issues and troubleshooting steps can minimize downtime and get your technicians
Truck transmissions have evolved: Here’s where they’re going next
Automated manual transmission (AMT) and automatic transmission manufacturers are crushing assumptions and setting new expectations in all trucking industry applications. Automatic transmissions are getting smarter and, in the AMT world, gone are the days of clunky, reverse-engineered AMTs. Today’s AMTs are, as PACCAR Vice President Landon Sproull put it, “purpose built.” “The gearing—overall ratio and
