Thought about a TKX yes and it is a good option - it is a tad smaller, lighter, and a bit cheaper then 6 spd. But I liked the ratios of the 6 spd better and wanted the two over drive gears. T56 Magnum has an outstanding reputation and is known for its shift quality and durability. But I have seen youtube reviews of TKX and people really like how it shifts once they get it installed.
