When does the torque converter start to shudder?
It generally occurs at part throttle and light acceleration, between 15 and 50 miles per hour, just before the shift to one of the top gears where the converter reaches “lock-up.” Since it is temperature-related, it tends to happen on hot days, after idling in traffic for long periods of time.
How to troubleshoot a car that shudders when turning?
Step 4: Turning at speed. If your symptom doesn’t show up at slow speeds, take the car out on the highway and find some long sweeping turns, both right and left, that you can take at speed sufficient to induce just a little bit of side force. If the shudder is more pronounced in left turns, it is associated with a problem on the right front.
Why does my car judder at low speeds?
As well as some of the causes of car stuttering mentioned earlier, moisture in the distributor cap can also make a vehicle jerk when accelerating. If your car is parked overnight in cold temperatures, condensation can form inside the distributor cap, causing the engine to misfire when accelerating at low speeds.
When do you need to replace a torque converter?
If there is excessive debris is still found within the transmission pan or the shudder keeps happening after servicing, then you may need to replace the torque converter. In some cases, you may need to have your transmission rebuilt. Continuing to drive with the shudder could cause your transmission to fail.
What kind of damper does a torque converter use?
This heavier duty damper and new Torque Converter Clutch lining along with fresh WS transmission fluid solved Bob’s “vibration” complaint and he was thrilled to say the least.” And I cant even do the 99 steps just to change my WS fluid correctly.
What kind of sound does a torque converter make?
The sound is similar to driving on deformed ‘washboard’ pavement, while shifting at low rpm in the last three transmission gears (4,5,6). Anyway, after 2000 km, I took it back to the dealer, and he test drove it, carrying the ‘Bob’ test; shifting into Sport mode during the rumble, and it would stop.
It generally occurs at part throttle and light acceleration, between 15 and 50 miles per hour, just before the shift to one of the top gears where the converter reaches “lock-up.” Since it is temperature-related, it tends to happen on hot days, after idling in traffic for long periods of time.
Why does my VW diesel engine hiccup when I accelerate?
After the engine is warm, when getting on a road, accelerate quickly through 2000 RPM to blow out soot. Some people think the hiccup is caused by the turbo: it isn’t. If the turbo stops, you will have tons of black smoke, and your car will limp or stop functioning.
What causes a Duramax diesel engine to heat up?
When the engine is working hard, the turbocharger is drawing in a ton of air, and the restrictive stock turbo inlet tube can effectively choke the VGT turbocharger causing the compressor outlet temperature to skyrocket, heating up the intercooler, and ultimately raising the temperature of combustion and the coolant temp.
What to do when your F150 shakes and shudders?
Replace joints by removing the bolts and nuts from the end of the drive shaft, then remove the shaft itself. The joints will remain attached to the drive shaft. Spray WD-40 on the joints at the end. After you have removed the U-joints, clean up the ends until they are nice and shiny.
When do you feel the shudder in your car?
The shudder vibration may be noticed mostly during light throttle acceleration of 30-64 mph (48-104 km/h) during steady state driving with the transmission not actively shifting gears. It also may feel like driving over rough pavement or rumble strips.
What causes a shudder in a torque converter?
A torque converter shudder vibration may be induced by the torque converter clutch in normal driving mode (with an expected TCC slip amount) and is most often due to TCC friction material/ATF degradation).
What’s the vibration frequency of a TCC Shudder?
If TCC shudder is present, a vibration peak will appear at approximately 43Hz +/-3Hz. (Fig. 18) If the vibration frequency follows engine, tire, or driveshaft speed, then it is not a TCC shudder vibration. An alternative diagnostic for TCC shudder is to road test the vehicle and monitor commanded and actual TCC slip speeds.
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 does it mean when your brake pedal shakes?
Well, if the brake pedal shakes, then, it is potentially a serious issue which is simply making your vehicle unsafe to drive. There are ample of causes of brake pedal vibration. However, the solution is only to get the vehicle to nearest service station right away, for avoiding any further damage.
What happens when you hit the gas pedal at the last light?
You’re running a little late, but sitting in pole position at the last light before hitting your employee parking lot. So when the stoplight turns from red to green, you punch the gas pedal, hoping to sail through the intersection a little, um, faster than usual. But instead of moving when you hit the gas pedal, your car hesitates.
What causes a truck to shudder when going over rumble strips?
These are both with in my skill set. I also found this on a truck site “A possible cause for the shudder is a bad torque converter clutch (TCC) solenoid or a bad torque converter clutch pulse width modulated solenoid (PWM). Thanks again.
