What this part is for
TREMEC TKX 5-Speed Transmission GM 26-Spline is a performance part builders add when the stock piece won’t do the job — whether that’s durability, flow, adjustability, or packaging in a custom build. Ask Grok with your year, make, model, and engine, or Call Us — confirm fitment once before you buy. Real people at Cunningham Customs handle the order.
