The shifter includes a micro switch for neutral safety. However, if you want reverse lights, we have a CAN relay module for that.
-Works with GMPP Connect and Cruise Kits (no programming needed)
-Works with LS/6L80 Gen IV tunes with a Corvette tune or Camaro tune with tap shift enabled. (requires proper DTC's to be disabled for ABS/BCM or tap shift won't work)
Contact us with any questions!
Shifter!

Flashback Friday. This was 2017 when we had our shop truck. 1969 C10 with a LT4/8L90 swap that we built for R&D purposes. A few years later we pulled this powertrain to install the LT5/10L90 kit that we developed!

- Notably, despite the LT5's limited production run, we continue to receive occasional orders for this configuration, a true testament to the LT5's appeal!

These guys are awesome. Reach out for your swap needs!

Tap shift Tuesday. This video from 2020 shows us installing the 10L90 gated shifter with tap shift and reverse light controls in our old '69 C10 shop truck. Like all our products, extensive testing is done is house. If you have a Camaro tune with a 10L90 or even CTS-V/Camaro 8L90 setup, you can use this gated shifter.

ARE YOU AWARE THAT WE PROVIDE CUSTOMIZED LAYOUTS AND HARNESS LENGTHS TO MEET YOUR SPECIFIC NEEDS? Many of our truck customers opt for under-the-seat installations, which require custom-made harnesses. This approach is particularly useful when working with aftermarket A/C systems or larger Gen V E92/E90 computers, as it allows for efficient mounting under-the-seat or under-the-hood.
