TH400 Ultra Case 2 SFI Racing Turbo 400 Transmission Case JW Performance 32310


The Ultra Case 2 is the best TH400 transmission case JW Performance makes and is SFI approved. No longer do you have to be limited to using a powerglide transmission to get a high performance transmission case. The Ultra Case 2 now gives you the option of using the 3 speed TH400 and having a superior performance SFI approved aftermarket case as the foundation of your transmission.

The JW Turbo 400 Ultra case 2 is a SFI certified transmission case that replaces the stock case on high performance and racing TH400 transmissions. Many competition sanctioning bodies require a transmission shield or blanket in higher horsepower vehicles. The TH400 Ultra Case meets the SFI requirements while also providing a stronger case to handle the demands of high performance.

SFI Certified High Performance TH400 Ultra Case

The original stock Turbo 400 case was never intended to handle the horsepower and torque levels of modern high performance and racing engines. Current racing Turbo 400 transmissions often use far higher oil pressures than the OEM GM case was designed for. The stock transmission case can deflect, distort and break in modern performance and racing automatic transmissions. If the transmission case is not stable under extreme loads, you will experience inconsistent transmission performance which will hamper your ability to win in your chosen form of motorsports competition.
