700R4 & 4L60E Rebuild Kits
    For those of you interested in building your own Heavy Duty, Off Road, Rallye, Street & Strip, Pro Street transmission, then you have come to the right place. I offer custom rebuild kits, that will give you the best of both worlds, smooth quick part throttle upshifts, quicker downshifts, firmer wide open throttle shifts.

    I offer these very complete rebuild kits to suit the above mentioned categories. They come with everything that is needed. In these rebuild kits I offer several choices.

    You can choose from which input sprag you desire (Borg Warner dual cage or the Raybestos SKF). Your choice of which type of 3-4 clutches you want (Borg Warner Hi-Energy or Raybestos Z-Pak) in all but Pro Street. Two different sunshells you can choose from in most kits (GM's heat treated or the Beast). There are other options not mentioned here. I have put together these options in such a way so that you cannot make a wrong choice, and I am always improving (updating) the rebuild kits.

    With the technical information that I can provide, DVD/VHS videos, ATSG build books, and the tools for building 700R4/4L60E's, you will be able to build a 700R4 or 4L60E transmission successfully. You can always call me in the evenings or weekends with questions and for assistance, 909 795-1876, or email me at dana@700r4l60e.com

700R4 & 4L60E Transmission Specialists

    With over 30 years of experience in HD to Strip Only transmission building, I have found many solutions to making a Heavy Duty or Performance transmission do the job correctly for your particular application.

   To get the best results with Heavy Duty, Off Road, Rallye, Street/Strip or Drag Racing, we highly recommend the Precision Industries or Edge  for the 700R4 & 4L60E transmissions, both in terms of performance & longevity.

 

    I offer the ATSG build books for each transmission rebuild kit, as well as the DVD/VHS videos for most units.

   These are the ATSG rebuild books needed to build the following transmissions:

 

Due to the amount of email questions, I have added a Q&A forum for all of your transmission & torque converter questions. Feel free to post your questions at any time.

    I have been concentrating on the problems of 700R4 & 4L60E, for several years now, and have come up with some "solid" solutions. The following products, (depending on the application of the transmission) have proven themselves highly successful:
  • Modified version of Trans-Go's 700R4 Performance Shift kit is tailored to match the setup you have (offers much more than the 700-2-3 Performance Shift kit). Offers smooth part throttle & firmer WOT shifts [exclusive]
  • Modified version of Trans-Go's 4L60E Performance Shift kit that is tailored to match the setup you have. Offers smooth part throttle & firmer WOT shifts [exclusive]
  • 9 Clutch Borg Warner Hi-Energy 3-4 clutch pack (good for over 800FWHP)
  • 10 Clutch Raybestos Blue Plate Special 3-4 clutch pack (good for over 850FWHP) [exclusive]
  • 16 Clutch Raybestos Z-Pak (instead of the normal 14 clutch count) [exclusive]  
  • Alto Carbon lined extra wide 2-4 band (use when over 750FWHP)
  • GM's heat treated or Beast sunshell
  • HD Steel sleeve with machined overrun piston & modified steel forward piston (reinforces the input drum) [exclusive] 
  • Sonnax 2nd gear apply servo (use when over 750FWHP) 
  • Trans-Go's vacuum modulator (4L60E) (for certain applications) 
  • Vigilante 9.5" lockup torque converter (for most applications)
  • Vigilante 10.5" lockup torque converter (for 4WD & Heavy vehicles)
  • Sonnax pinless accumulator for 4th with matching HD spring
  • Sonnax pinless forward accumulator for the 4L60E
  • Hardened (RC52) thin accumulator pins for 4L60E forward & second accumulators (made in Germany) [exclusive]

    Paying very close attention to details & clearances, I am able to get many vehicles in the 11's, quite a few in the 10's, a few in the 9's, and the quickest & fastest of these is a 3,560 lbs. (with the wife driving) street driven 1995 Firebird with a 2000 LS1 motor & trans, he built the transmission himself using the Pro Street Performance Upgrade, and has run a best of a 9.49ET @144.6mph in the 1/4 mile. He had over 300 passes with this transmission, until he lost a driveshaft at the 1,300 foot mark.

    Ed Wright of www.fastchip.com had used my Performance Upgrade in his high 9 second 1996 Firebird with hundred's of successful passes on it, has since changed class and now runs a TH350.

    Rick Abare's highly successful bracket raced high 9 second 1996 Firebird has well over a thousand passes with my 4L60E transmission, and still going. This shows you what this transmission is capable of, so it can be done, and you can do it with the right parts & direction. View our Online Catalog
 
    For the best in transmission oil for HD, Off Road, Rallye, Drag Racing, Strip Only, or any Extreme use, I have recommended for years, Lubrication Engineers Monolec 7500 at www.le-inc.com/ This is not a synthetic oil.
 
    For the best in Computer Programming and Performance chips, Ed Wright at www.fastchip.com is the man to talk with. He is friendly and very knowledgeable when it comes to OBD1 & OBD2 programming, and is the best out there.

    Due to the amount of email questions, I added a Q&A forum for all of your transmission & torque converter questions. Feel free to post your questions at any time.

    I offer the 700R4, & 4L60E, transmissions in the Heavy Duty, Rallye, Street/Strip, Pro Street, and in the Pro Street Elite. I also carry a complete line of Heavy Duty & Performance Rebuild kits, along with Trans-Go Shift kits & Performance Shift kits for most of the other Chevrolet, Ford, & Mopar transmissions.
