4L65E Performance Transmission 2WD 750HP for Chevy GMC LS 2007-2008 15-Pin

REBUILT 4L65E PERFORMANCE TRANSMISSION — RATED TO 750 HP

Is your transmission showing these symptoms?

• Harsh, delayed, or no upshifts / downshifts
• Burnt or discolored fluid and overheating
• Broken sun shell or 3-4 clutch debris in the pan
