When do you feel a shudder going up a hill?
When do you feel a shudder going up a hill?
Specifically, when I am climbing a hill and the transmission is in a higher gear, say 4th and the RPMs are relatively low, say 1800, I feel a shudder as the car goes up the hill. When I let my foot off the gas the shudder stops.
When does a car shudder at highway speeds?

Why does my car make a shudder when I go uphill?
The shudder sounds like a slipping torque converter clutch (TCC). This is commonly known as TCC shudder. There is a mechanical clutch that should “lock up” in higher gears at 45+ mph in order to improve gas mileage. When the clutch slips under load, it produces a shudder-type vibration.
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.
Why do I get a shudder when I go uphill?
This is commonly known as TCC shudder. There is a mechanical clutch that should “lock up” in higher gears at 45+ mph in order to improve gas mileage. When the clutch slips under load, it produces a shudder-type vibration. Try adding a product called Dr. Tranny’s Shudderfixx to the transmission fluid.

When does a GM Truck shudder under load?
It will usually do it under a slight load, and is most common between 1200 and 1500 rpms. It will do it for a couple seconds, stop, then do it again a couple times. Usually it’s not under load for long periods of time, but with traffic I notice it more often as I’m on the gas and off more frequently. Is there a loss of power?
How often do you drive a Suburban Tahoe?
I’m going back today to see what they came up with.,I drive 3,000 mi. a month,this vibration is pounding struts,shocks,steering and springs to an early death. What happened to you,did they fix it?
Why does my car shudder when going uphill?
Q: Car shudders when accelerating and going uphill, seems like a loss of power, particularly around 1500 rpms. When I’m accelerating sometimes my car will shudder or shake, seems like it’s coming from the engine area. It happens more often when I’m traveling uphill, but it sometimes happens in regular conditions.
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.

What causes the drive train to shudder at 30 mph?
The torque converter lockup in our case slipped and caused the shudder at 20-30 mph @ about 2000 rpm. In my case, the mechanic installed a torque converter that was re-designed to handle the load and fortunately, I only had to pay a deductible.

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.
