Skip Shift Eliminator Guide for Manual Challenger Owners

What Is Skip Shift (CAGS)?

If you own a manual Challenger, you've probably noticed that under certain conditions — light throttle below about 35 mph — the transmission forces you from 1st directly to 4th gear. This is called CAGS: Computer Aided Gear Selection, and it exists purely for fuel economy compliance.

The system works through a solenoid in the shifter assembly. When the PCM detects low throttle position, low engine load, and a speed between roughly 15–40 mph, it activates the solenoid to physically block 2nd and 3rd gear gates. The result: you're forced into 4th whether you like it or not.

It's annoying on back roads, confusing on the first drive, and gets old fast. The good news: it's very easy to defeat.

Method 1: CAGS Harness Delete Plug (~$25)

The cheapest and most popular solution. A CAGS delete plug is a small wiring harness that plugs into the skip shift solenoid connector under the hood and sends a constant 12V signal, telling the solenoid to always stay deactivated.

Install time: 5 minutes, no tools required.

Cost: $20–$30 on Amazon or Summit Racing.

Reversible: Yes — unplug it and the OEM behavior returns.

Check engine light: No — it does not trigger a code.

Look for "CAGS Delete Plug" or "Skip Shift Eliminator" compatible with Dodge Challenger (2009–present, 5.7L or 6.4L). Most are universal.

Method 2: PCM Tune

If you're already getting a custom tune on your Challenger, have your tuner disable the CAGS function in the PCM calibration. This is a single parameter change and takes about 30 seconds to toggle — just ask when you're getting your car tuned.

Advantage over the plug: Slightly cleaner solution with nothing extra under the hood.

Disadvantage: Requires a tune — not worth getting one just for this.

Method 3: Tazer JL / ZF8 Mini (Not Recommended for This)

The Tazer unlocked some Challenger features but is primarily for automatic models. For manual owners, the CAGS plug or PCM tune are the right solutions.

Does Defeating Skip Shift Affect Warranty or Emissions?

The CAGS plug does not affect emissions — the system only controls gear selection, not combustion or exhaust. It will not trigger a check engine light. Dealerships cannot tell you've installed it unless they physically look for the plug under the hood.

Other Manual Transmission Mods to Consider

While you're here, two more mods that manual Challenger owners love:

Barton Short Throw Shifter: Reduces shift throw by about 35% for quicker, more precise gear changes. One of the best-reviewed mods for the manual Challenger. Cost: ~$375–$450.

Clutch Stop: A small rubber or metal stop that limits how far the clutch pedal travels after the engagement point. Allows faster, shorter clutch strokes. Some are adjustable. Cost: $30–$60.

Both combine with a CAGS delete to give the manual Challenger a noticeably sportier feel without touching the engine.
