Summary
This technical bulletin provides a procedure for software update and transmission flush to correct a slight shutter felt during gear shift.
2 Affected Products
Vehicles
Condition
Some customers may comment on a slight shudder felt during gear shift at slow speeds below 64 km/h (40 mp/h) with light throttle application.
Cause
This condition may be caused by possible torque converter clutch (TCC) shudder on reapply after a shift.
Correction
If confirmed to be a TCC shudder while monitoring TCC slip speed during the concern, or the concern goes away when TCC is commanded on with the scan tool and the concern is present at 64 km/h (40 mp/h) or below during the gear shift, reprogram the Transmission Control Module (TCM) with the latest calibrations including following the procedure in SI that requires to perform Service Fast Learn (SFL) after programming TCM. Also, drain and refill the transmission using DEXRON VI as per SI.
Important: A minimum of 200 miles (322 km) needs to be driven after the drain and fill to confirm the repair.
Note: If the shudder occurs above 64 km/h (40 mp/h) or with the TCC commanded on TSB 17-NA-317 should be reviewed.

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 following are the supported interface tools:
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.
