LS3 495hp TKX 5-Speed Manual Connect & Cruise Package



We at Pro Touring Store put the latest Tremec TKX 5-speed manual transmission in place of the T56 6-speed offered by Chevrolet Performance, so you get a more compact transmission for your classic ride!

The TKX transmission features internals similar to the T56 Magnum, so the shifts are smooth, and sustain higher RPM use (as compared to other 5-speeds). 
Additionally, the TKX 5-speed is super compact, fitting into muscle cars such as 67-81 F-Body, 64-72 A-Body, Chevy Nova's and others, without modifying your transmission tunnel. 

Mixing the capable LS "Hot Cam" with the powerful 6.2L LS3 takes affordable performance to a great, new level - 495 horsepower and 473 lb.-ft. that will wake up your vintage Camaro, Chevelle or "shoebox" Chevy. The 4L70-E four-speed overdrive transmission backs the LS376/480 with strength and durability. Put this combo to work in your classic cruiser and enjoy a great balance of performance and efficiency!
