6L80e/6L90e guide to tuning with hi-stall converters.

When fitting a hi-stall converter to a VE or VF with the 6L80/90e transmission with the T43 TCM controller. You must follow the below procedure to make the calibration accept the mechanical modification you have just performed.

1. Open the Transmission tab in your vehicle’s calibration in VCM Suite.
2. Navigate to Torque Converter > General.
3. Locate the TCC Desired Slip section. (Pictured below)                                             
4. For the A/C Off section – you must ZERO/0 each individual gear.
5. For the Use DOD Slip section – turn the switch to Disabled and then ZERO/0 the individual gears also.
6. Next, click on the Apply/Release sub-tab. The next step is very subjective to stall speed, vehicle combination and driver’s opinion.
7. A good start is to max out the 3^rd and 4^th gear converter lockup parameters. Shown below.                                                                                                                                                                                                                                                       
8. If you choose to raise or lower the 5^th and 6^th gear converter lockup/apply, please ensure you raise the release by the same number or percentage.
