Nissan Tech Tip: Chirp Noise on 2-3 Upshift
If a 1999-2000 Quest or Altima exhibits a "chirp" noise as the automatic transmission shifts from 2nd to 3rd gear, particularly when accelerating the vehicle with only 1/8 throttle applied, the noise may be coming from the high clutch assembly during operation. This noise can be eliminated by adding two bottles (200cc each, 400cc total) of Automatic Transmission Fluid Treatment to the transmission. If the incident occurs, follow the below procedure to confirm and resolve it.
Automatic Transmissions: From Mechanical to Electronic to Hybrid
A long time ago in a service bay, preventive maintenance for an automatic transmission was an oil change, band and throttle linkage adjustment. The 1960s saw the end of external band adjustments. In the 1970s, the drain plug went away and the pick up screen was replaced with a filter. In the 1980s, a turbo
Brake Lathe Care and Feeding: Breaking the Cycle of Neglect When it Comes to Machining Rotors
How often do you use your brake lathe? Once a month? Once a week? Once a day? If you’re like most undercar shops, your brake lathe is humming along for at least several hours per day, every day. Even a one-man shop will find a brake lathe to be an indispensable piece of undercar equipment.

Photo 2). Another change for the 4.6L in 2006 is that it no longer uses a knock sensor. Both, the 4.0L and the 4.6L use a PCM-controlled heated PCV valve. The PCV valve on the 4.0L SOHC engine is located in the back of the left valve cover, mounted horizontally, and is well hidden from
Tech Tip: Honda Ticking Noise from the Engine
A ticking noise may come from the V6 engine of 1994-’97 Passports during normal operation. According to Honda, the probable cause is one or more hydraulic lash adjusters (HLAs) does not fully extend due to varnish buildup inside. This condition results from exceeding the required oil and filter change schedule.
Diagnosing & Servicing Automatic Transmissions
To prevent having any service from being over sold or under sold, it is important to not only know that a particular service should be performed, but also why it should be performed. That knowledge can also help you spot when to recommend that service, and when not to. When speaking about transmission fluid, the
Diagnostic Solutions: Fluid Maintenance…Selling Needed Services Vs. “Wallet Flushing”
Good import shop managers stay on top of their annual workflow by placing jobs like timing belt and brake replacements into categories that can be tracked on a historical basis. If a shop has faithfully tracked the kinds of work flowing through its service bays during the past 10 years, it might become apparent that

Tech Tip: What is Viscosity Breakdown?
All of us in this business understand an SAE 5W-20 oil is thinner in viscosity than an SAE 10W-30 and that the "W" stands for winter, but that’s probably about where it stops even though there is more to the story.
Tech Feature: Getting Up to Speed on Hybrid Vehicles
Hybrids are hot. As the price of gasoline goes up, so does the demand for new vehicles that can squeeze more miles per gallon from every drop of gasoline. Hybrids do that by combining the best of both worlds: electric power for low-speed, stop-and-go driving, and gasoline power for highway cruising and long-range driving.
