Condition/Concern
Some customers may comment on a shudder or chuggle when accelerating at low speeds of 12 to 15 MPH (19-24 km/h) in second gear.
Customers may also comment on the same shudder or chuggle when accelerating at speeds of 30 to 40 MPH (48-64 km/h) when accelerating in 6th gear.
These conditions are most likely to occur when driving on a smooth road up a slight or moderate grade when accelerating.
Recommendation/Instructions
Please refer to the latest version of PIP5303 New Service Calibrations For the ECM and TCM That Effects a Variety of Concerns.
Update the ECM and TCM as instructed.
Note: Performing this calibration update may not totally address shudder or chuggle concerns.
No additional repair attempts should be attempted to address the concerns listed above.
These concerns are due to normal operation of the automatic transmission and the torque converter clutch.

Reprogramming
GM Diagnostic/Programming (TIS2Web)
Approved J2534 Device with TIS2WEB can reprogram 1996 and later All GM Modules.
To obtain the latest electronic controller calibration information for your vehicle, go to https://tis2web.service.gm.com/tis2web and enter the vehicle's 17 character Vehicle Identification Number (VIN) and select 'Get CAL ID’.
You can then compare the latest part number with the actual number installed on the vehicle to determine if a reprogram is needed.
The Service Programming System (SPS) application is part of the TIS2Web system. To program an ECU, the SPS application must communicate with the vehicle control modules using the proper J2534 programming interface tool.
The Tech 2 supports model years 1996 and beyond. With the addition of the CAN Diagnostic Interface (CANdi) module, Tech 2 is fully backward compatible with current Tech 2 functionality and operates transparently when diagnosing non-CAN-equipped vehicles.
Servicing the next generation Global A vehicles will require the diagnostic software, GDS2, Global Diagnostic System 2 running on a local PC device while the MDI is connected to the vehicle. The GM MDI is the Global Diagnostic tool for future vehicles starting with Global A vehicles.
The GM MDI was introduced in the fall of 2007 for Pass-Thru programming and offers faster programming speed. It can be used to perform Pass-Thru programming on all vehicles built since 1996 and into the future. Click here to view a list of GDS supported vehicles.

file a lemon law claim thats what i am doing
Have you made any progress with your claim?
So, I buy a brand new truck and have the calibration performed to address the shuttering. It does nothing to decrease the shaking and I’m just supposed to say it’s okay because it’s normal operation? Why would I want to drive a truck that literally shakes in my hands like it’s going to stall out around 1000 RPM every time I try to increase my speed? It’s ridiculous.
Hey Mike have you fixed this problem yet or anything?
