The Tremec TKX shifting capability has been proven to 10,000rpm behind NA 13B PP engines, a significant improvement over the Tremec TKO. A case redesign has improved strength, so in theory the TKX should handle well over 850hp at the wheels. In addition, this redesign has reduced the physical size of the TKX when compared to the TKO, resulting in easier fitment to early Mazda’s.

In car removal: The TKX can be unbolted from our alloy bell housing adapter, and from our modular steel bell housing. This enables ease of removal without affecting the release bearing etc. This is especially useful in vehicles with an exhaust system that gets close to the bell housing. In addition, the alloy adapter can be unbolted from the steel bell housing for release bearing access, without removing the bell housing from the vehicle or disconnecting the release bearing hoses.
