Building your own 700R4, 4L60E including the 4L80E, from Heavy Duty to a Performance transmission, then these "very complete" rebuild kits from Heavy Duty to Pro Street Elite for the 700R4, 4L60E & 4L80E transmissions, are what you want and need. Many using these automatic transmission rebuild kits have been able to get their vehicles in the 11's, the 10's, and quite a few in the 9's successfully. These kits offer you the best of both worlds, smooth quick part throttle 1-2 upshifts, quicker downshifts, and very quick wide open throttle shifts. We are always updating the rebuild kits to improve longevity. This shows you what 4L60E's and 700R4's are capable of, and you can build a Heavy Duty or Performance transmission yourself, or with the help of a competent builder. Complete 700R4, 4L60E & LS4L60E transmissions are available from Heavy Duty to Pro Street Elite and come with a 2 year warranty. You can call me most anytime, including evenings and weekends with any questions call or text me at 909 435-5360
