    The TCI 400000 Trans-Scat valve body kit is a shift kit for 1966 to 1991 TH400 automatic transmissions. It is designed to deliver solid shifts and improve downshift and kickdown control while retaining full automatic operation in drive. By reducing transmission slippage and lag it provides a harder, more positive shift and allows manual downshifting on demand. With most setups the transmission can be held in first gear until an upshift is selected. For a TH400 Pro Super kit, see part number 228800.
