What’s New With Functional Fluids?
Late-model vehicle technology is changing. Wider tires, active safety systems and AWD technology are not only influencing how vehicles perform, but also the service and maintenance requirements of their functional fluids.
How To Diagnose NVH Complaints In Drivetrain Components
Thanks to advanced technology, modern vehicles operate with fewer noise, vibration and harshness (NVH) complaints than ever before. Consequently, when a NVH issue arises, it’s most likely caused by worn drivetrain components like universal joints, constant velocity joints or wheel bearing hub assemblies. In any case, NVH complaints can often be the most challenging to diagnose when you can’t duplicate the driving conditions under which they occur.
Wheel Bearings And Locking Hubs
Automatic hubs are used on many 4×4 trucks to disengage the front wheels when four-wheel drive is not needed. Disconnecting the front wheels reduces friction and may improve fuel economy as much as one mile per gallon depending on the vehicle. A one mpg difference may not sound like much, but every little bit helps.
ASE A2 Prep: Transmission Diagnostics
The transmission game has changed. Solenoids, sensors and computers have replaced vacuum lines, governors and kick down cables on modern automatic transmissions. The tools have also changed: Scan tools, scopes and meters have replaced pressure and vacuum gauges.
American Powertrain Announces New Pro-Fit 6-Speed System For 1968-’82 C3 Corvettes

Oil Consumption On Manual Transmission Acura Vehicles
In this updated TSB from 2013, Acura discusses how some 2011-‘13 TSX models with manual transmissions can develop an oil consumption problem. The TSB states: “If you do not see any other factors contributing to oil consumption, consider engine braking as the possible cause.”
Audi Start-Stop System Information
This informational TSB applies to Audi vehicles with a start/stop system. The start/stop system allows automatic engine stops and starts. Although the driver expects it, the engine may not automatically be switched off due to many different factors.
