If you're looking for an easy way to add overdrive to your GM A-Body car the new TKX is the perfect design for the swap.  With it's streamlined case design and the removal of the mounting bosses on the lower section of the tail housing, there's only this new shifter to be installed for an easy modification free swap. If your car is already equipped with a four speed you can retain the bellhousing, mechanical clutch linkage, and flywheel to simplify the swap and keep it within budget.

 

The A-Body side shift modification retains the factory console positioning for the shift lever and the offset shift lever attachment can be rotated 360° for centering the shift lever in the opening.  Ideal for the 64-67 Chevelle/Malibu, & 64-72 Buick, Pontiac, and Oldsmobile A-Body cars that want to retain the factory 4 speed console.  

This option is available on all TKX models, please pick a gear ratio from the drop down below or contact us for a recommendation. 

*Some early cars may need slight tunnel modifications at the rear of the transmission for proper clearance*
