The Haltech Ti4L unit allows easy control for GM's popular 4L series of automatic transmissions. Designed as an expansion module for the NEXUS ECU and VCU range the Ti4L will be programmed via our NSP software, or Rebel LS users will be able to follow the simple set up wizard in the Haltech Connect App. Easy set-up is not the only feature! We've also developed smart long-term learning strategies via closed loop line pressure control, which means shifting gets better the more you drive.
