The Late 4L60E is our most popular transmission build here at Novak. We have seen hundreds come through our shop and we enjoy building them every time. The 4L60E was the defacto automatic found in Corvettes, Suburbans, trucks and other durable platforms for nearly two decades at GM. They now constitute one of the most sought-after transmissions for Jeeps.
Featuring a low first gear (3.06:1) and a terrific overdrive (.70:1), the 4L60E meets Jeep owners with broad usability, from low-range crawling to high-speed freeway trips to the trailhead.
The 4L60E is built on the heritage of the 700R4, and shares many qualities with its predecessor. Every Novak 4L60E build starts with the late, 6-bolt tailhousing / separate-bellhousing case. It gets carefully disassembled and is deep-cleaned and inspected before assembly. We then replace any questionable components with factory or better replacements and upgrades, depending on the customer's chosen build level. New clutches, seals, bushings, bearings, and gaskets are assembled to specs that exceed later model years' OEM V8 levels.
LubeGuard additive is included for longevity and shift quality and each package includes the new dipstick and tube.
One great advantage is that we can install the appropriate Novak transfer case adapter and output shaft during the build. This saves you having to open up the transmission to install the output shaft or paying to have it done. That along with our package discounted price, it saves you time, money and potential problems. Transmission to engine adapters (if necessary) are available and in addition to the pricing as listed below. Please inquire.
Our factory style builds are OEM style replacement transmissions using the applicable GM output shaft, but that may require the use of the vehicle owner's original tailhousing (either 2wd or 4wd) to complete the installation.
Adapted builds are designed primarily for installation into Jeep vehicles and include the installed aftermarket Novak output shaft, adapter kit and urethane crossmember rear mount, as indicated for the customer's scenario.
Your 4L60E can be ordered ready to join (or joined) to the following Jeep transfer cases:
We can do a full rebuild of your transfer case if you ship it to us. Many upgrades components are available. It will be pre-installed to the transmission and ready to install in your Jeep.
Level I, $1890. ($2375., adapted)
Our "Stock Plus" transmission that meets or exceeds the factory original version integrating a few key improvements over the originals. Recommended for engines up to 325 HP and 325 ft. lbs. torque. All components upgraded to late model V8 specs including and additionally:
Level II, $2230. ($2705., adapted)
Our Level II features all the above improvements, and takes it further for even better longevity and more power handling capability for engines up to 400 HP and 400 ft. lbs. torque, including:
Level III, $2870. ($3340., adapted)
Our "all out" transmission includes many additional subtle improvements. Time consuming steps are taken to assure maximum strength and life including minimizing clearances and other blueprinting steps. We can customize this transmission even further for specific needs including full manual control, trans. brakes, race spec converters, Kolene steels, harder race spec shifts, etc. For level III transmissions we prefer to talk with you to make sure that you get the best transmission for your application as these units can get highly specialized. Recommended for engines above 400 HP and 400 ft. lbs of torque. Includes all features of Level II, plus the following:
A 4L60E installation is typically done in conjunction with an Generation III+ GM engine conversion into the Jeep. These engines include the Chevrolet Small Block V6 & V8, from 1996-2010+. Though Gen. III installs are much more prevalent, Gen II and Gen I motors installations are possible but will require the use of a separate transmission computer controller which may add significantly to the expense of the total installation. For these scenarios, we fully recommend the 700R4 instead, which is essentially self-controlling.
We can also integrate your 4L60E into a full TurnKey powertrain package with engine, transmission, transfer case and controls all assembled, tested and ready to install in your vehicle.
Your transmission package is palleted, wrapped, fully insured and ready to bolt into your application. Novak will seek the best competitive shipping rates with our extensive trucking networks. It will arrive at a location of your choosing, though we strongly recommend a business location with a dock / forklift for delivery, as residential and liftgate fees can add up to an extra $100. per delivery.
