Looking for products to upgrade your 200-4R automatic transmission? Here are the most popular products we sell for the 2004R transmission:
Oregon Performance Transmission offers two rebuild kit options for the 2004R automatic transmission: a standard rebuild kit and a high performance version.
- A Transtec overhaul set with rubber seals, gaskets, o-rings, metal clad seals, and Teflon sealing rings, needed to complete your rebuild.
- All Raybestos Red HP friction clutch plates
- All Alto black Kolene Steel plates
- New fluid filter
- Kevlar Intermediate – 2nd gear band
- Bushings for the pump and case
This kit is performance rated and will handle 300% more heat and horsepower, torque and abuse than the standard clutches. The steel plates are Kolene coated with a special friction material that keeps them from slipping like the smooth steel are prone to do. This will give you a more positive clutch engagement.
This newly upgraded high performance shift kit fits year 1981-up and contains the following:
- Billet aluminum 2nd gear HP servo
- .500 boost valve
- Large low-reverse boost valve
Full installation instructions are included with this kit
The new dual feed 3rd gear circuit increases direct clutch holding capacity by 200%. This kit works for both street and strip use and can be installed with the transmission in the car.
From the factory the 2004R transmission had trouble with the stator support wearing out prematurely. For that reason it is always recommended to upgrade to this heat treated style if you still have the stock one in your transmission. You can find the upgraded stator support here under part number NTP-45812R.
10 vane / 13 vane pump kit
This is a must for high horsepower, heavy abuse applications, but is also definitely recommended if you just want to increase the life or durability of the transmission. This 10 vane pump will help to eliminate the line pressure fluctuations and high RPM pressure drops seen with the stock pump configurations. This kit includes a 10 vane rotor, vane rotor guide, pump slide, 10 vanes, 2 upgraded hardened heavy duty vane rings, O-ring, and slide seal. You can find the 10 vane pump kit here under part number NTP-K51819A.

The 2004R transmission is part of the Turbo-Hydramatic series and is sometimes referred to as the 200-4R, 200R4, 2004R, 200-R4, TH200-4R, THM200-4R, and even the MW9.
An easy way to identify the 4 speed automatic 200-4R is by its irregular shaped pan and non-removable output shaft housing.
