What causes torque converter shudder in Silverado 1500?
I have 99′ silverado 1500, 2wd, 5.3 4l60e transmission with a split drive shaft and a G80 rear diff. he has the same just a 00′, both around 120,000. i am getting a shudder at about 15-24 mph on acceleration and his is about 40-55, i believe from other forums we have a break down of tranny fluid and that is creating the torque converter shudder.
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?
What kind of transmission does a Silverado 1500 have?
When diagnosing a shudder vibration condition on some 2016-2018 Silverado, Sierra; 2016-2020 Tahoe, Suburban, Yukon; 2019-2020 Silverado 1500 and Sierra 1500 models equipped with 5.3L V8 engine (RPO L82, L83, L84) and 6L80 6-speed transmission (RPO MYC), it’s critical to determine the source of the vibration in order to make the proper repairs.
Why does my car shudder at low RPMs?
I sometimes notice it in lower gears at low speeds, and it happens on the highway for a couple seconds at a time pretty regularly if I’m cruising around 1,500 rpms. If I drop to 5th gear and get to around 2,000 rpms, the shudder goes away.

What’s the speed limit on a GMC Sierra 1500?
You described it to a T. Mine does it around 45 to 55 MPH. I put in Lubeguard as well and it didnt help mine. I have a 2006 GMC sierra 1500. I have a similar problem with a 2007 5.3 4 speed- new body style. It started around 80k- replaced a pump solenoid and it was OK. Started again around 125k.

I have a 2006 GMC sierra 1500. I have a similar problem with a 2007 5.3 4 speed- new body style. It started around 80k- replaced a pump solenoid and it was OK. Started again around 125k. It just seems to bump slightly when under a load in high gear between say 40 and 50 mph.
What’s the problem with my Silverado Trans Shudder?
It started around 80k- replaced a pump solenoid and it was OK. Started again around 125k. It just seems to bump slightly when under a load in high gear between say 40 and 50 mph. Not enough load to make it downshift, like when going uphill. give it some gas and it downshifts and goes away.
How can I tell if my car is having a shudder?
The use of the CH-51450 PicoScope automotive oscilloscope and the CH-51450-A NVH kit can help confirm the disturbance frequency and determine if the disturbance tracks to engine speed (chuggle or misfire), road speed (tire vibration), or remains constant across various inputs (TCC shudder).
Why does my truck shudder when I put it in overdrive?
Mine seems to do it mostly in overdrive. When the engine RPM’s are low and the truck is in overdrive you can make it shudder by giving it a bit more gas, but not enough to make it shift into another gear. It also seems to do it on hills on the highway.
What kind of acceleration does a GMC Sierra have?
Alright I’m going to do the best I can to try and describe what is going on. I have a 2005 GMC Sierra with the 5.3L H.O. 139K. The truck starts and idles without an issue. Durring light acceleration and at low speeds (city driving 35 mph or so) the truck seeems to run fine.
