This 2007 Jeep Wrangler originally came with a 3.8 L EGH V6 and 545RFE five-speed automatic transmission. The owner eventually swapped the V6 for a 392 ci Hemi V8 from Arrington Performance. The motor made 397 horsepower and 417 lb-ft of torque to the 37-inch tires thanks to a Magnuson supercharger making 6 psi of boost. Great news for the Wrangler but bad new for the transmission. So the Jeep went to Arrington Performance for a built NAG1 five-speed automatic transmission.
