Five Features that make NAG-1 a Fantastic Transmission

If your hotrod is powered by HEMI and can push torque up to 1000hp-1350hp at the crankshaft, NAG-1 transmission can be an excellent choice for you.
While the transmission is popular for its excellent torque capacity and affordability, there are some features that make it one of the best transmissions currently available.


NAG-1 is a five-speed overdrive, electronically shifted automatic transmission which features a torque converter lockup. The transmission was first launched to replace 722.3/722.4/722.5 four-speed transmissions in the early 2000s. Due to the high torque produced by the transmission and its affordability, it is also used for turbocharged engines for 4-cylinder applications and a number of commercial vehicles since the launch.


While it is the torque and affordability of this transmission make it highly popular, it comes with a number of features that are equally impressive.


Here are the 5 most useful features of this transmission are:

High Flow Filter

The filter in NAG1 transmission makes use of synthetic media and also features a bypass valve. The filter has a very large dirt carrying capacity, allowing you to continue using it for longer durations without any service intervals. Be it light-duty or heavy-duty applications, the high flow filter of the transmission will always provide you with the best of results.

High Energy Clutches

With high energy clutches, engaging and disengaging of transmission, power, especially from the driving shaft to the driven shaft becomes far too quicker. The clutches increase the friction surface while also making sure that the clearance of clutch pack or the thickness of steel plate is not sacrificed. They not only help in improving the holding capacity when driving on high roads but also increase temperature stability.

Torrington Bearings

The high-quality bearings offered by Torrington are already very popular in the industry. As compared to flat-type hardened bronze or steel washers generally used in many of the models, these roller thrust-type bearings feature several small needle rollers that are radially arranged inside a cage which fits between the block and cam sprocket for taking the thrust loads. The bearings are well-known for taking an abundance of loads with minimum friction.

Cryogenically Treated Components

The components of the NAG-1 transmission are treated to cryogenic temperatures for removing residual stresses while also improving wear resistance. The process is also known to enhance the corrosion resistance of components by precipitating the micro-fine carbides. Overall, the components which are cryogenically treated can offer better performance in demanding conditions and have a longer lifespan.

Improved Oil Pan

Transmission needs to remain properly lubricated to perform flawlessly. It is the oil pan where the lubricating, cooling fluid for the transmission is stored. The improved design of the oil pan in this transmission ensures that the transmission will never run of the lubricating fluid. With easy access to the lubricating fluid at all times, the transmission offers better performance without any breakdowns or damages.

These are 5 of the features that make custom NAG1 transmission perfect for any powerhouse engine. Make sure that you buy the transmission from a reputable service provider to make sure that it offers years of flawless results. Moreover, some providers offer the wide range of customization options to ensure that the transmission perfectly suits your requirement.
