Convert your TH400 to a 2 speed transmission with this valve body kit.
BTE's all new billet aluminum valve body kit contains everything needed to convert your TH400 transmission to a two speed unit. By using the two speed design, the transmission can utilize the transbrake in second gear, allowing the car to launch a much higher starting line ratio than a powerglide. This feature is useful in high powered race cars with limited traction. BTE's aluminum design eliminates unused passages in OEM designs as well as lowering overall mass.
