TKO 600 5-Speed Manual Transmission

The TREMEC TKO 600 is a robust 5-speed manual transmission engineered for high-torque applications, suitable for both street and performance racing. This transmission offers a significant upgrade over stock 4-speed units, providing enhanced drivability and efficiency. Key specifications include a torque capacity of 600 lb-ft, making it ideal for powerful engines. It features a 1.125-inch input shaft with 26 splines and a 31-spline output shaft. The 0.64:1 overdrive ratio is a notable benefit, allowing for a substantial reduction in engine RPM during highway cruising, which translates to better fuel economy and a quieter ride. This GM-specific variant (TCET5009) is designed for compatibility with GM 4-speed bellhousings. The installation may require attention to the fitment between the transmission, clutch housing, and engine, as well as ensuring the input shaft correctly mates with the pilot bearing. The transmission can be mounted at either 19.5” or 16.75” from the transmission face, offering some flexibility in installation. TREMEC transmissions are known for their durability and performance, and the TKO 600 is a popular choice for hot-rodders looking to upgrade their drivetrain.
