Review CHEVROLET Case Jeep Trnsfer Automatic Transmission Rockcrawler fits WRANGLER 700R4 TJ 1997

The TJ 700R4 NP231 automatic transmission, specifically designed for the 1997 Jeep Wrangler Rockcrawler, is an exceptional upgrade for off-road enthusiasts seeking improved performance and durability. This transmission system is a seamless combination of the 700R4 four-speed automatic and the NP231 two-speed transfer case, offering seven forward gears and a low range option.

The TJ 700R4 NP231 transmission boasts robust construction, ensuring reliability in the toughest off-road conditions. The 700R4's four forward gears and overdrive provide smooth and efficient power delivery, while the NP231's low range gear set lets you conquer steep inclines and tackle rugged terrain with ease. The combination of these two components results in a well-balanced system that delivers both speed and torque.

The TJ 700R4 NP231 transmission features a hydraulic shift system, ensuring precise and quick gear shifts. This system also includes a gear-driven torque converter, which is more durable and reliable than a friction-type converter, making it a perfect choice for the demanding off-road environment.

In addition, this transmission system is compatible with aftermarket lockers and differentials, allowing you to further customize your Wrangler to suit your specific off-road needs. The TJ 700R4 NP231 automatic transmission is a must-have upgrade for any serious Jeep Wrangler Rockcrawler enthusiast, providing unparalleled performance, durability, and versatility.

1. Durability: The TJ 700R4 transmission is known for its reliability and durability, which is essential for off-road adventures.

2. Power: The NP231 transfer case provides an additional low range, enhancing the Wrangler's crawling capabilities.

3. Convenience: Automatic transmissions are more user-friendly and less demanding than manual transmissions, making driving easier, especially in heavy traffic or when towing.

4. Adaptability: The TJ 700R4 NP231 combination is widely used in the Jeep community, making parts and upgrades readily available.

1. Cost: Repairs and maintenance for automatic transmissions can be more expensive than for manual transmissions due to the complexity of the system.

2. Performance: Automatic transmissions may not provide the same level of control and responsiveness as manual transmissions, which some enthusiasts prefer.

3. Weight: The combination of an automatic transmission and a transfer case can add weight to the vehicle, affecting its performance and fuel efficiency.

The 1997 Wrangler Rockcrawler with a TJ 700R4 NP231 automatic transmission is a reliable and durable option for off-road enthusiasts who value convenience and power. However, the potential for higher repair and maintenance costs, as well as the impact on performance and fuel efficiency, should be considered. Ultimately, the decision to purchase depends on individual preferences and priorities.

If you prioritize convenience, power, and reliability, a 1997 Wrangler Rockcrawler with a TJ 700R4 NP231 automatic transmission could be an excellent choice. Be prepared to invest in regular maintenance and repairs to ensure its longevity. Alternatively, if you value control, responsiveness, and cost-effectiveness, you may want to consider a manual transmission option.

Details:

This keeps the rear driveling as long as possible. The low first gear ratio This negates the use of the fussy TV cable to get the line pressures functioning properly. You can use the TV cable for shift points.

It has a polished aluminum pan with a drain plug and a provision for a temperature sending unit. 06 is excellent for rock crawling. This is a no brainier for any used tyranny before installation.

And a stainless braided dip stick part 3700fm. This kit came with the 23 spline 700R4 output shaft that is installed.

It has a stainless braided TV cable from lobar part JD 2700ht. Although before installing this in your vehicle I do recommend changing the clutch packs and band. This has been a great transmission for me for many years. It has been in my Jeep since 09.

This is a great 700R4 built by pact called their mega raptor. Attached to the rear is advance adapter's transfer case adapter for new process 231,242,247,249 and 2410r transfer cases. The lock up has been hard wired inside the tyranny so you can manually lock up the converter.

03 and I added the tic valve body 09. I decided to get a tyranny with a full manual reverse valve body so I am parting with this one.

Very critical in the short wheel based Jeeps I also installed a tic constant pressure valve body. 07 my Jeep Tj with 350 ABC is just for fun and not used as a daily driver. Included is the 2000 rpm stall converter with lock up clutch. So I am uncertain of the mileage but I am sure it is well under 20,000 miles.

Pact built this from a 1990 core and the serial is 0chm7160.
