TH400 Pump Rebuild Kit - Pro Performance & Parts

This collection of components is designed for the restoration of the oil circulation mechanism within a specific automatic transmission. It typically includes seals, gaskets, and potentially wear items like bushings, essential for restoring proper hydraulic function to the unit. An example includes replacing worn seals to prevent internal pressure loss.

Effective maintenance of this component is paramount to preserving the performance and longevity of the associated transmission. Restoring optimal hydraulic pressure is vital for correct shifting and overall transmission health. Over time, the deterioration of these components leads to diminished operational effectiveness, necessitating refurbishment. Its development has mirrored the evolution of automatic transmissions, adapting to improvements in materials science and engineering.

TH400 Full Manual Valve Body: Performance & Control

This performance modification replaces the original control mechanism within a TH400 automatic transmission. Instead of relying on the vehicle’s computer or internal hydraulic pressures to dictate gear changes, the driver assumes direct control. Shifting is achieved by physically moving the gear selector, which then directly manipulates the valve body to engage the desired gear. This setup eliminates automatic shifting and provides immediate response to driver input.

Implementing this modification offers enhanced control over the vehicle’s power delivery, particularly beneficial in racing or high-performance applications. The ability to select and hold specific gears maximizes engine output and provides predictable performance. Historically, this type of modification has been favored in situations where precise control over the transmission is paramount, enabling drivers to tailor the transmission’s behavior to specific driving conditions or track layouts.
