Stop guessing at your TV cable adjustment. Bowler's Tru-Shift kit makes proper 700-R4 and 200-4R throttle valve calibration automatic — bolt on the bracket and cam, install the cable, run the throttle to wide open, and you're done. No carb removal. No pan drop. No pressure gauges. No more burned-up transmissions from wrong TV cable settings.

NOT compatible with:

Quadrajet, Rochester, or any original-style 1- or 2-barrel carburetors
FiTech LS Fuel Injection intakes
2.0 Holley Sniper and Sniper EFI Dual setups

Photo required before ordering: Quickfuel, Holley Street Warrior, Brawler, and Aces carburetors. Email photos of the carb base and throttle arm to info@bowlertransmissions.com or call 618-943-4856 before ordering.
