What causes a vibration in a 6l transmission?
Other sources of a vibration include insufficient damping or isolation of the engine or driveline, an irregular combustion event, and Active Fuel Management (AFM) disturbances. TIP: DEXRON 6 is the only approved automatic transmission fluid (ATF) to be used with 6L transmissions (RPO MYA, MYB, MYC, MYD) at this time.
What causes a Duramax to overheat in the summer?
Overheating typically occurs while towing in the Summer months, and is most prevalent in 2005 or earlier models (2006+ models received a larger radiator and fan). Overheating often occurs as a result of a fan clutch failure, preventing the engine fan from providing supplemental airflow as necessary to keep the engine from overheating.
Are there any flaws in the Cummins Duramax?
Still, and just as we exposed the shortcomings of the almighty Cummins, the Duramax isn’t without its flaws—some of them catastrophic. For example, did you know the injection pump on the LML version is prone to coming apart and wrecking the entire high-pressure fuel system when it does?
Why is the roller lifter on my Duramax not working?
Unfortunately, the latter scenario plays out more often than seizures do. Typically, the roller lifter (or bucket) that rides on the CP4.2’s shaft (the part that’s driven up and down via the plunger) fails due to lack of lubrication or debris hampering its ability to operate in an unobstructed manner.
Why is my Chevy Silverado making a clunking noise?
A loud clunk from the front end during low speed turns, which is particularly noticeable on unimproved roads. The clunk vibration travels up to the steering wheel, particularly while turning the wheel. GM has released numerous TSBs, either calling to grease or replace the intermediate steering shaft.
Why does my Suburban make a rattling noise?
If you have ever listened to a big cam or small cam cummins idle and heard that rattly sound from the front of the engine? Thats basically what my suburban is sounding like. I plan on pulling the inspection cover this evening after work to check torque converter bolts.

Where does the lifter sound come from on a Chevy Silverado?
You can hear lifter click best around the top of the engine, and isolate the noise with a stethoscope against the valve cover. It will occur at idle and increases as you rev the engine, continuing even when the engine is warm. Valve lifter noise is detrimental and should be addressed quickly.
Why does my car make a vibration when I accelerate?
The vibration I’m going to cover here tricks most mechanics into thinking it’s caused by a tire or bent rim. This vibration only happens when driving under heavy acceleration, like when you are approaching the highway trying to merge into the speeding traffic, or on a jackrabbit start from a traffic light.
Why does my Toyota Sienna shake when accelerating?
Since purchasing back in May, we’ve got all new brake pads and 2 new rotors. Also replaced bearings in two of the wheels. Now, we’re noticing significant shaking and vibrations only when accelerating. Seems to be worse when accelerating hard.
What causes vibration in the CV joint when accelerating?
Damaged Inner CV Joints Can Cause Vibration on Acceleration. Damaged inner CV joints cause vibrations on acceleration and are very difficult to diagnose because the damage is so inconspicuous. You can only see it once the inner CV joint is removed from the vehicle and cleaned of all grease and debris.
What does it mean when your car vibrates when you accelerate?
You have probably experienced a car shaking when accelerating. Different vibrations will mean different things. And you should know this by now. No good news should be expected when your vehicle starts to vibrate. It does not matter if the vibrations come after you accelerate, while in motion, or if the car is idle.
Damaged Inner CV Joints Can Cause Vibration on Acceleration. Damaged inner CV joints cause vibrations on acceleration and are very difficult to diagnose because the damage is so inconspicuous. You can only see it once the inner CV joint is removed from the vehicle and cleaned of all grease and debris.
When do you Lift your foot off the accelerator do you feel the vibration?
You feel this vibration only when the vehicle is accelerating. If you lift your foot off the accelerator to maintain cruising speed, the vibration will disappear; if you press the accelerator in order to pass someone, the vibration will return.
