What We Do: 40+ Years of Experience

  • I have been concentrating on the problems of 700R4 & 4L60E, for several years now, and have come up with some "solid" solutions in terms of longevity.  
  • By paying very close attention to details, clearances, and the right combination of parts, I and others using my automatic transmission rebuild kits have been able to get many vehicles in the 11's, quite a few in the 10's, and a few in the 9's successfully.
  • This shows you what 4L60E's and 700R4's are capable of. So it can be done, and you can do it with the right parts & information.
  • Ed Wright of www.fastchip.com is highly recommended to solve the computer problems of the OBD1 and OBD2 that are used with the 4L60E transmissions since 1993. 
  • If you have a 4T65, EV/GT transmission, Talk to David Norris at Triple Edge Performance. They offer stock to highly modified 4T65Es, upgraded parts, solutions that work, and technical support to assist the do-it-yourself customers, before - during - and after the rebuild. Go to: http://tripleedgeperformance.com/Home-Page.html They will give you the best information for the 4T65E transmission.

With over 40 years of experience in Heavy Duty to Strip only transmission building, I have found many solutions to making a Heavy Duty or Performance transmission do the job correctly for a particular application. We offer the 700R4 & 4L60E transmissions in the Heavy Duty, Street/Strip, Pro Street, and Pro Street Elite. These transmissions, the 700R4 and 4L60E, come with an "24 month" warranty.                                      

To get the best results with the Heavy Duty through the Pro Street Series transmissions. We highly recommend using the Circle D or Edge torque converters with 2 Year Warranties for the 700R4 & 4L60E transmissions.
