Now available - The new gear indicator for swap projects using the 6L80, 6L90 or 8L90 transmission! Easily plugs into your existing OBD-2 port, or available with a quick connection to a new Speartech harness. This allows you to easily see what gear you're in when you're tap shifting with our tap shift switch box, or floor mounted tap shifter!

Now confirmed working for the 8L90 too! Works in factory applications. Just plug into your OBD port. Tested and confirmed functionality on a 2017 Sierra Denali 6.2 / 8L90 factory stock truck!

Available display colors: Red, Blue, Green, or Yellow.

The indicator measures 2" tall, 1.25" wide, .5" thick.

Note - Disconnect the gear indicator when doing any read/write functions (tuning) to the ECM/TCM.
