Anyone Done A Gearing Change?

[Jet Ski Puller]

2008 4.6 V8.

The PCM shouldn't care, right . . . as long as both rear and front are the same gearing?

The PCM won’t know the difference.

However, your speedometer & odometer will be off, MPH/RPM shift points will be off, and the ABS will not be 100% accurate.

Same as changing tire size.
