Show original supplier description

The Tremec TKX 5-speed transmission kit is engineered for 1964-1967 GM A-body vehicles, providing a robust upgrade for models like the GTO and Oldsmobile. This transmission boasts a 600 ft-lb constant load rating, making it suitable for street and strip applications and highway cruising. Key internal components include 4616 chromoly gears and shafts, a one-piece countershaft, and brass cage bearings, all contributing to its durability and performance. The ProFit TKX installation kit included with this package contains all necessary components for a comprehensive swap. This includes the Tremec TKX transmission, a TREMEC Flip Shifter designed for OE 4-speed shift positions, a 1330 solid yoke, and adapters for both mechanical and electronic speedometers. It also comes with a tunnel patch, reverse light wiring harness, a low-profile ISO-X ballistic mount, a roller steel pilot bearing, and a white shift knob with a 5-speed pattern. Hardware, warranty, and installation instructions are also provided. This transmission kit is compatible with any GM 4-speed bell housing and requires a 26-spline clutch disc, which is sold separately. The aluminum case transmission features a 2.87:1 first gear ratio and a 0.64:1 fifth gear overdrive ratio, enhancing both acceleration and fuel efficiency. An optional upgrade to the TKO Extreme is available, increasing the torque capacity to 950 ft-lbs with upgraded components and cryo treatment for high-performance engines.
