In my years of service as an Automotive Professional, I have seen too many reasons as to why you should torque those lug nuts. I’ve seen wheels come off, brakes damaged, broken/stripped lug nuts, bolts and studs, etc., and I have seen this repeatedly by Technicians as well as the Do-It-Your-Selfers for one simple reason – they don’t properly torque the Lug Nuts on their vehicle…

Yours truly, forum Host and fellow Veteran Automotive Professional,
Based on my experience, I would say that close to 40%, maybe more, of temperature related transmission issues are due to torque converter drain back, and loose valve body bolts (meaning not properly torqued to spec.). Torque converter drain back is commonly due to a poor trans pick-up filter. But also can be caused by loose valve body bolts (not just the main bolts, but the bolts that retain the two halves as well). Loose valve body bolts not only allow drain-back of trans fluid, but also allows torsional twist, binding and deformation of the valve body which can cause sticking or binding valves – especially when cold. However, after the vehicle is warmed up, the fluid fills up the torque converter and trans and operates normally. Continue reading
The above title is a question that customers ask themselves all the time, “Do car companies really care about me?” The simple answer is Yes! But a better question is – Do they hear you, known as the “customer’s voice?” Let’s first look at several ways that customers talk to manufacturers in “Manufacturer Talk” so-to-speak… Continue reading
NHTSA (National Highway Transportation Safety Administration) receives complaints when a dealer or manufacturer resolution for their vehicle has not been reached. In the past, vehicle improvements have been based on production and warranty data, and not a huge focus on the “Customer Voice.” Why would a manufacturer not want to hear the customer voice?
We hear the terms “Voltage Loss” and “Voltage Drop” test frequently in the Automotive industry. But most refer to it as what’s is really a Voltage “Drop” test. This is incorrect, these are two separate test with two separate purposes – however, many-times the same failure result can be determined with both test. So what is the difference between the two test, and why do we perform them?
Well, it’s actually what it states: Continue reading
