This high performance Grand National type 200-4R comes with a larger than stock intermediate billet servo which gives firmer 1-2 and 2-3 shifts. This Superior / Fairbanks servo has an 11% larger apply area than the Grand National servo. It comes with the Mega Valve that raises the fluid pressure and gives a firmer shift and more holding power in all the gears, elevated pressure regulator spring, high output pump slide spring and an oversize low / reverse boost valve. These are the valves you’ve heard about. All of our Level 3 high performance 200-4R transmissions come with a performance Transgo Shift Kit installed and a heat treated sun gear shell. The stock seven-vane pump is replaced with a 10 or thirteen-vane high performance / high volume pump. Included is a 4th gear converter lock-up switch. The stock intermediate band is replaced with a black carbon fiber band. Also included in this package deal is a heavy-duty balanced stall converter that has furnace-brazed fins, a Sonnax carbon fiber clutch and needle bearings for added strength (#2). This stall converter can be ordered with stall speeds of 1800, 2000, 2300, 2600 or 2800 RPM and gives a faster launch than a stock converter. It also comes with a universal-fit throttle-valve cable and dip stick. The 200-4R transmission will fit all GM motors that have full size bell housings. This is a perfect choice, if you have a non-Chevy motor. You can expect a 30 to 40% increase in gas mileage (over a 3-speed) on the road. Every Transmission Tested on the PATC Dyno. Good for motors up to 500 horse power using pump gasoline, see chart below. This level 3 200-4R transmission comes with our hardened input drum and shaft.
