Everything you need, except the transmission, to swap a true 6 speed automatic behind your 6.2 or 6.5 diesel! This will work with both mechanical and electronic injection trucks (DB2 or DS4) and 6L80 or 6L90 transmission.

This kit will require the willingness to perform final tuning on your end.

Includes:

PCS transmission communication module with universal wiring harness
Base transmission tune file
Custom multi-disk torque converter

Utilizes proper low stall speed for diesel applications
Uses all 6 mounting bolts
Weighs in at 20# less than a factory 4L80E converter. This is a HUGE rotational weight savings

Bellhousing adapter kit with hardware and dowel pins

Provides 360 degrees of support for the 6L bellhousing flange
Ensures proper spacing for the included torque converter

ARP torque converter bolts
ARP flexplate bolts

Compatible with stock 6.5L flexplates or our billet flexplate offering

6AN Transmission line adapter block
Crank sensor breakout harness for DS4 trucks
Wiring instructions
Informational documents for transmission selection
Informational documents for transfer case re-use or swap compatibility

Benefits of the swap:

Fully automatic shifting and torque converter lockup in auto mode
Manual tap shift control for upshift and downshift

The 6L can hold 100% on deceleration unlike the 4L80
Automatic downshifting can be left enabled in tap shift mode
If your final gear ratio is still high, you can set it to start in 2nd gear

Multiple shift strategies. Pattern A, B, and Tap Shift. I.E. "Tow Haul" mode.
Gain 6th gear, an additional overdrive over a 4L80e
Torque converter lockup is far more useful due to the better gear spread. We don't need to wait until 45+ mph to go into lockup like with a 4 speed.
Enables you to lower the final gear ratio, if desired, to maximize economy and torque multiplication gains.
The end user has full control over programmability/adjustments of shift points, shift firmness, and torque converter lockup. This often isn't the case with a factory 4L80e.

***All features may not be available in some transmissions. They can be available if you properly flash the TECM calibration in the transmission with GM SPS, however. Work with your transmission builder during the build to confirm before final assembly. For example, a truck TECM might not have full tap shift capability in some operating systems and flashing a Corvette or similar OS would enable it***

Additional Options available by request:

HP Tuners MVPI 2 Interface for tuning the transmission's internal TECM/TCM

This is required if you don't already have access to one

Paddle Shifter tap shift kit
Toggle switch tap shift kit
DS4 trucks will require a tune to the factory ECM/PCM to disable factory automatic transmission control and trouble codes.
Remanufactured TECMs and SPS programming
Tuning support
