    The TKX has a rounded case and is streamlined to the max to fit inside tight transmission tunnels with no cutting in most applications. The shifter plate has a low profile and the shifter is nice and compact. It's great right out of the box, but if you need a shorter throw or a relocated shifter, Butler Performance can build you a custom kit for your Pontiac

    Comments:
    I ordered my (bare) .68od TKX in the spring of 2022 from Butler Performance. Did the swap/install myself. All was fairly easy swapping out the ST-10 for the 5 speed. Have been using it daily for over 2 years now and well over 40,000 miles behind a 400 and a 455 with no issues. I really like the ratios and is so much better to drive at hiway speeds especially. Highly recommended this trans and gear set. I could never go back to a 4speed trans for anything I drive much. The TKX is such an improvement.
