The B and M AUTOMOTIVE TH400 Transpak is a professional-grade transmission shift kit designed for drivers who seek sharper, more responsive gear changes from their TH400 automatic transmission. This kit is ideal for high-performance street and strip applications, enhancing the driving experience without the need for internal transmission modifications.
The Transpak operates by recalibrating transmission fluid pressure curves and shift solenoid timing, which allows for quicker clutch pack engagement and firmer band application during both upshifts and downshifts. Its compact design, measuring 10.2 x 1.9 x 11.3 inches, facilitates easy external installation without disassembling the transmission, making it accessible for experienced DIY builders.
Enthusiasts and mechanics favor the TH400 Transpak for its compatibility with a variety of TH400-equipped vehicles, including vintage Chevrolets, Pontiacs, custom trucks, and street rods. This shift kit not only enhances shift feel and line pressure response but also maintains OEM reliability, making it a valuable upgrade for those looking to refine their powertrain performance.
