Show original supplier description
The TCI 327500 is a specialized planetary gear assembly designed to enhance the gear ratio capabilities of automatic transmissions. This component is engineered to work with TH350 transmissions, providing a significant improvement in low-end torque and overall performance. This planetary gear set features a 2.75 ratio for 1st gear and a 1.52 ratio for 2nd gear. These ratios are crucial for optimizing the transmission's performance, especially in applications requiring increased pulling power or better acceleration from a standstill. The planetary gear set is a fundamental component that enables automatic transmissions to produce their various gear ratios. Installation of this planetary gear set involves the basic disassembly and reassembly procedures for a Turbo 350 transmission. Modifications may be necessary for certain components, such as the low/reverse piston, to ensure compatibility with the new, larger gear set and park pawl. It is recommended that this part be installed by a qualified technician.
