What makes the transmission shudder at 30 mph?
What makes the transmission shudder at 30 mph?
Eagle Transmission Rebuilt the transmission about a year ago and it started shuddering again after a few weeks. I’ve taken it back 2 more times for the same thing (repairs are under warranty) and it continues to shudder when shifting at about 30 mph & 40mph.
What causes drive train shudder at 110, 000 miles?
We had the same shudder at 110,000 on our 2012 AWD. We had some time left on our extended warranty that we purchased from CarMax when we bought the car with 19,000 miles. It was a failed torque converter. It’s is a well known problem among GM mechanics, at least in Southern California. It probably should have been a recall.
What causes vibration at 25 to 30 mph?
Discussion in ‘ 5th Gen 4Runners (2010+) ‘ started by Kennyp, Nov 24, 2018 . Just noticed a vibration at 25 to 30 mph that feels like driving on corrugated road. It only happens between the speeds I mentioned. No new tires, rims or anything added. Nothing stuck to rims.
Why does my drive train shudder when I shift gears?
Now to meet more stringent fuel mileage standards, the auto makers are locking up the torque converter as soon as they deem possible whether the transmission is through shifting through the gears or not. This has been putting more force on the torque converter locking mechanism than it was originally designed for.
Why does my car shudder at 35 mph?
A shudder or vibration may develop while driving at speeds between 35 and 40 MPH. Our technicians tell us this condition is commonly caused by a failed automatic transmission torque converter. It is recommend to replace the torque converter and install an updated powertrain control module(PCM) to correct this concern.
Why does my traverse shudder at 30 mph?
I have a 2012 traverse. There is a shudder under acceleration that starts at 30 mph and will continue to 40 mph were it goes away. I don’t think it is a transmission issue as the transmission will shift with no affect on the shudder. this issue started when I had about 97000 miles and has gotten worse.
What causes Acura MDX to shudder at 35 mph?
Acura Acura MDX Shudder or Vibration While Driving at Speeds Between 35 and 40 MPH Problem Description A shudder or vibration may develop while driving at speeds between 35 and 40 MPH. Our technicians tell us this condition is commonly caused by a failed automatic transmission torque converter.

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’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 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.

What causes a shudder when accelerating from a stop?
My ’15 Outback 2.5L Limited has had a slight but noticeable and repeatable shudder when lightly accelerating from a stop regardless if turning or accelerating straight forward. I think its coming from the CVT when it does its low speed/mild acceleration shift-point shifting.
When does CVT shudder during mild acceleration shifting?
CVT shudders and hesitates around 15mph to 22mph during light or even acceleration, especially on an incline. Brisk acceleration runs fine. Dealer drove it, felt it, tested it and said it was normal. Irritating, but I guess I’m getting used to it. My 3.6R OB 2015 does the exact same thing.
