The manual transmission in a 2008 Jeep Wrangler is a six-speed NSG370 manual, paired with the 3.8-liter V6 engine. The vehicle’s other available gearbox that year was a four-speed automatic (42RLE).
In 2008 the Wrangler sits within the JK generation (launched for 2007). Jeep offered two primary transmissions for this era: a six-speed manual for those who wanted direct control in off-road conditions, and a four-speed automatic for smoother highway driving. The six-speed is commonly identified by the NSG370 designation and was used across most 3.8L V6 configurations, including Rubicon trims that emphasized off-road capability.

What buyers and owners should know
When evaluating a used 2008 Wrangler with the manual gearbox, consider the condition of the clutch, linkage, and the synchronizers. A well-maintained NSG370 should shift smoothly across gears, including into reverse; grinding or difficult engagements can indicate wear or linkage issues. If you’re shopping for a Rubicon or other off-road-focused model, the manual transmission is typically the same NSG370 setup, but overall wear can vary with use.
Summary
The 2008 Jeep Wrangler’s manual transmission is a six-speed NSG370, designed to pair with the 3.8L V6 engine. The alternate gearbox option for that year was a four-speed automatic (42RLE). For off-road enthusiasts and drivers who prefer precise control, the NSG370 represented the standard manual choice in the JK-era Wranglers.
