TJ Installation Page 2

The TJ Wrangler began to be manufactured in 1997. This vehicle model is normally equipped with either an automatic transmission (Torqueflite & 42RLE), or a manual transmission (AX5, AX15 & NV3550). The installation photos in this section relate to both automatic & manual transmission applications.

Shift Indicator Switch

The Atlas is designed to accept the stock TJ 4WD indicator switch. This switch only indicates the dashboard 4WD light. Unlike the previous YJ model, TJs have a full time engaged front axle. This switch is installed into the Atlas shifter housing without the use of any spacer or washer. Note: Since the front axle is always turning, the TJ uses a C.V. front yoke.

Shifter Installation

The twin stick for the Atlas 2 speed TJ application has three designs for a hard linkage. P/N 303003L should be used with a AX5, AX15 & NV3550 transmissions, and P/N 303002L should be used with the Torqueflite automatic transmission. These shifters are designed specifically for these applications and fit the stock console. P/N 303002U should be used with the 42RE and the NSG-370 transmissions or any vehicle that has had a drivetrain swap. This shifter has a long extension from the front of the Atlas and can be modified to fit most applications. We also offer two cable linkage shifters for the TJ’s. P/N 303020 works on all TJ’s with the exception on the 42RLE transmission, and P/N 303021 only fits the 42RLE transmission. The cable shifters bolt directly to the floorboard and enter into the vehicle through the stock console.

The Atlas 4 speed shifter options fit the same as the 2 speed shifters, however; there are a few different components so we also have different part numbers. P/N 344003 should be used with a AX5, AX15,NSG-370 & NV3550 transmissions, and P/N 344002 should be used with the Torqueflite & 42RLE automatic transmission. P/N 344002 should also be used with any vehicle that has had a drivetrain swap. This shifter has a long extension from the front of the Atlas and can be modified to fit most applications. We also offer a cable linkage shifters for the TJ’s. P/N 303020 works on all TJ’s. The cable shifters bolt directly to the floorboard and enter into the vehicle through the stock console. Note the NSG370 transmission should also use a 1/2” spacer when bolting to the Atlas 4 speed.

The reduction portion of the Atlas 4 speed can be either a cable linkage or an electric shift unit. P/N 344020 is the cable linkage and P/N 344021 is the electric.


The stock floor mount (shifter and linkage) is removed before initial installation.


The console and driver's seat should also be removed for ease of installation.


The sticks will come up through the stock floorboard hole. You will be required to cover a small portion of the stock hole. The rear driver’s side will need a piece of sheet metal to be added. Make sure the handles move freely and don’t touch the floorboard. Interference will cause the unit to pop out of gear.


Place the stock console in its original position to test fit the Atlas handles. Rotate the twin stick assembly so that it aligns with the console slot. Once the correct position is obtained, remove the console again.



Shift the Atlas into 4WD low (both handles forward), verifying at least a 1/2" clearance between the handle and the body. Test fit the shifter boot and boot ring. You will need to add a small piece of sheet metal at the REAR of the boot to extend the floorboard. Check the shifter boot and the handles for any interference or binding. Fasten the shifter boot and boot ring to the floorboard using high temperature silicone for an airtight seal around the boot area. Note:Sometimes the shifter boot will tend to bunch up, causing the unit to pop out of gear. We have found that if you apply a small amount of grease where the boot and handles contact, it will help to prevent this problem.
