In teaming with TransGo®, TTS supplied the knowledge for the power and Allison Shift Kit TransGo®, supplied the knowledge to get it to the wheels. The Shift kit is a fine tuned setup designed to work with TT

During kit development engine torque and horsepower were increased to over 900 ft. Ibs. and over 500 Hp. We installed our shift kit and torque converter and tested with a 25,800lb. GVW on an 8% grade with no slipping, no codes and no clutch damage. After this test, the truck was then placed on the dynamometer at full throttle and full load, then slowed at full throttle from 90mph all the way down to 35mph. Once again, no slipping, no codes and no clutch damage.

When installing the TTS / TransGo® kit you should follow normal rebuild procedures and replace any worn or damaged components.

TTS Multi-Plate Torque Converters*
If your factory transmission is being run with power levels higher than OEM settings you may find deterioration on one or more clutch packs. TTS is offering an upgraded Torque Converter and transmission upgrade kit. We will require your old converter back in order to waive the core charge.

15 years of proven Multi-Plate reliability The torque converter has two basic functions, fluid coupling and lockup. The torque converter in the Allison 1000 series needs some improvements in both of these areas. The stock torque converter simply isn't designed to handle the increased power that more and more customers are putting into their Duramax Trucks. Installing the TTS Multi-Plate Billet Cover Torque Converter easily addresses this issue. The three clutch discs in the Multi-Plate converter with will not slip even when running extremely high power levels.
