Vehicle has a vibration or shudder (seems to be in the drivetrain) at 60 to 80 KM / hr mostly if you give is a little gas or make it work a little going up hill. It disappears or is reduced at lower or higher speeds or if you take you foot off the gas and coast

SOURCE: front end vibration and shudder on turning vehicle off

I had a similar problem with my 2005 Envoy. It turned out that the bearings had to be replaced. Both sides. I hope its not your problem, it was expensive.

Have your tires checked for any unusual wear or pitting and make sure that they are balanced right. If they are even just a little bit out of balance it can cause your back end to vibrate. Hope this helps. Good luck!

I would be more inclined to look at the U-joints at either end of the drive line. Bent tubes usually cause vibration at speed. Jack up both rear wheels and put gearbox in neutral. Spin the wheels by hand and observe the drive line for being bent as it turns. A rare problem which allows the rear axle to twist under acceleration might be possible.

SOURCE: Vibration

your highway acceleration problem could be a coil problem. Not sure if that year of chev has coil packs or not but experienced same thing with ford 5.4L. went through 3 coil packs and did the same thing each time before biting the dust. Transmission seems to be sticking on the 1to2 upshift and could be a sticking solenoid in the valve body of the tranny. If the shifting problem persists then the tranny deffinately has to be rebuilt. It's made it quite far if tha is the original tranny, you cant expect too much life out of it if it has been worked hard. I highly doubt a fluid change would help at all. Or if you want, you can buy a can of new truck from GM for about 25 to 35 thousand bucks! Typically works great!

SOURCE: 2006 gmc 2500 vibration around 60 mph stops when I let off gas

Usually a vibration is due to one or more parts that have become worn or damaged. I'm not sure why you mentioned the tires but don't disregard them unless you know that they are fine. Check for correct inflation (on the door jam), for uneven tread wear, or bubbles and damage.
Other things that can cause a vibration is the front-end needing an alignment, a tire that is unbalanced, worn out steering components (like a wheel-bearing), defective u-joints and/or an unbalanced drive-shaft, or low gear-oil level in the drive-axle can cause damage to the ring & pinion gear. The damage would primarily be on one side. So when you let off the gas pedal the sound goes away. Check as much as you can and let me know how it is going.

Shudder could be the lockup torque converter if it is an automatic transmission. Another one would be the drive axles. Check the CV joints and u-joint in the drivetrain. If the shudder comes and goes with load changes, it could be either. However, to tell if it is the torque converter, watch the tachometer when the shudder occurs. If the RPM rises slightly, then drops off as the shudder stops, it is the torque converter. There is an additive for this issue that can be purchased an any parts store, called shudder-ease. Hope this helps you.

2007 HONDA ACCORD SECOND GEAR SHUDDER


Well, you did a really good job of describing the symptoms, but you didn't do so well describing the car. Are we talking about an automatic or standard transmission? are we talking about a four or six cylinder engine? You are asking about a drivetrain problem without giving any information about what drivetrain the vehicle is equipped with.

With all that said, IF we are talking about an automatic transmission being pushed by a V-6 engine, then there is a Technical Service Bulletin (TSB) that matches the symptoms you are describing. In this case, the problem is most likely being caused by a deformed or damaged exhaust pipe "A" mounting bracket.

Inspect the rubber bracket for cracks or torn rubber. If the bracket is damaged replace the bracket. Bend the stud on the exhaust pipe if necessary to get the stud to go through the bracket as straight as possible so the stud does not "ground" against the sides of the bracket. (see diagram)

Between 50 and 60 mph there is a loud shudder type of noise and vibration from below my gas pedal..not sure what is cousing this at this speed..my truck is a 2005 Chevy silverado 4x4 2500 i put it in...


This sounds like the front drive shaft that may have worn u joints. Put the vehicle in park, set the brake and proceed to shake the front drive shaft up and down to inspect for wear. Let me know what you find.

I think my automatic transmission modulator valve is going out because it jerks and vibrates when i accelerate anything above 50 MPH.


90 % of the time jerking or vibration is usually caused by the engine and not the transmission. The most common cause is cylinder misfiries caused by the ignition system that cause the vehicle to ****, stumble, or shudder which make it appear and feel as though the transmission is the cause. Most transmission problems will cause harsh shifts, slippage, and/or delayed engagement but rarely jerks or vibrations. I'd start by looking at the spark plugs, plug wires, and coil packs to make sure they are all ok first before going any further. The reason most of these problems are more noticable over 50 mph is that the torque converter clutch is engaged at this point and it provides a solid connection between the engine and drivetrain which makes engine misfires more noticable. Good luck, hope this helps a bit!

Automatic shudders on some gear changes.


This car has both options of auto transmission plus manual gear **** so the only reason it can shudder when the clutch is not fully released and thus takes some time, that's when it shudders, but on accelerating this will not happen cos the centripetal clutch has enough torque such that the clutch is pressed hard to the cam & therefore no shuddering. On cruising speed the probability of clutch slipping making the car shudder. Thus changing the clutch assembly ought eliminate this problem....sodeep

It's a step-by-step process. If it only happens on acceleration then it is a drivetrain problem. Start verifying from the outer cv joints and go in from there

Vibration shudder at around 30km


Hey Pontiac,

There are two things, firstly get your front wheel rims put on a lathe machine to check for distortion, if not, then get the wheels balanced on a digital tyre balancer.

let me know if this works
