ATS Co-Pilot Transmission Controller with 5-Speed Allison 1000 for Chevy/GMC (2001-05) 6.6L LB7 Duramax

The ATS Co-Pilot Transmission Controller  Chevy/GMC (2001-05) 6.6L Duramax LB7 with 5-Speed Allison 1000 gives you better control over how the transmission in 2001-2005 GM Duramax shifts and locks up. Electronic upgrades like this are the simplest way to fix soft shifts and lockup behavior that the factory programming does not handle well once a truck is modified.

The transmission control module decides shift timing, line pressure, and converter lockup. Factory programming is built around stock power, so once a truck is modified, better electronic control is what keeps shifts firm and lockup consistent.

ATS Diesel Performance has built diesel transmissions and performance parts since 1993. ATS designs, engineers, and manufactures most of its products in-house at its Arvada, Colorado facility, and tests them at altitude on the same long grades its customers tow on.
