Silverado 2500HD Automatic Shifter Cable Kit 19434387

This is a two-piece automatic transmission shifter cable kit, upper and lower cables with the inline connector, replacing GM 19434387. It is listed for the 2001-2006 Chevrolet Silverado 2500HD and 3500 and GMC Sierra 2500HD and 3500 with the column shifter. On these trucks the upper cable runs from the steering column shift lever through the firewall and the lower cable runs to the range selector lever on the transmission. The kit includes the cables and routing ties.

These cables wear at the ends and stretch over time, especially on work trucks that see heat and road salt. Common symptoms are a column shifter that no longer lines up with the PRNDL indicator, a truck that will not start because it is not fully in Park or Neutral, a key that will not come out of the ignition, a shift lever with no feel between detents, and in the worst case a cable that snaps and leaves the truck stuck in one gear. Before replacing the cable, confirm the lever on the transmission moves freely by hand and that the adjuster at the lower end has not simply slipped.

To install, put the column lever and the transmission lever both in Park and block the wheels. Disconnect the old cable at the column and at the transmission lever, release it from its brackets, and pull the upper section through the firewall grommet. Route the new cables along the original path clear of the exhaust and steering shaft, seat the grommet, snap the ends onto the column lever and transmission lever, and lock the adjuster with both ends in Park. Then check every range against the indicator and confirm the truck only starts in Park and Neutral.
