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.
With the DVD's, ATSG rebuild books, and the technical information that we can provide, you should be able to build your automatic transmission "of your choice" successfully, the first time, with our automatic transmission rebuild kits. 700R4 & 4L60E automatic transmission rebuild kits
