American Powertrain’s New White Lightning Tremec TKX 5-Speed Shifter


With the reveal of Tremec’s new TKX 5-speed, the manual transmission aftermarket have been in a tizzy to adapt the revolutionary 5-speed to their catalogs. With a whole segment dedicated to modern transmission upgrades for classic muscle cars, the advent of the TKX is certainly a boon to the performance enthusiasts – and no one sees that better than the team at American Powertrain.

As the new Tremecs begin to pour in from the loading bay, American Powertain is hustling to get these transmissions ready to fix the literally thousands of applications that their catalog offers. With that, American Powertrain just announced its short-throw White Lightning shifter for the new gearbox. If you’re looking for “lightning quick” 2-3 shift action, you gotta check out the new White Lightning below:

Cookeville, TN (March 9, 2021)… American Powertrain introduces an all new White Lightning shifter for TREMEC TKX 5-speed transmissions. The new TKX already shifts smoothly out of the box but American Powertrain takes it to the next level. Bolting on a White Lightning shifter shortens the shift by 30% and allows multiple shifter positions.

White Lightning shifters feature American Powertrain’s patented RevLok system that locks the offset in place, and independent adjustable centering springs that allow the customer to tailor the shift feel within seconds ensuring a lightning quick 2-3 shift action. This unique shifter has billet construction throughout with a two-piece aluminum body and a weighted billet steel shifter core providing excellent feedback and durability at the limit. Stainless steel countersunk fasteners and the lowest profile of any TKX shifter ensure excellent clearance for tight tunnels.

American Powertrain’s Revolution shifter has an eight-way adjustable offset, is available in four lengths, and covers a full 64 shift positions including most stock 4-speed and custom console locations for GM, Ford and Mopar. 

The White Lightning Shifter is available in American Powertrain ProFit transmission kits or can be purchased separately for any existing TKX 5-speed transmission. Prices start at $329.
