After patiently waiting 11+ years, I decided to go with the SST. I previously ran the Keisler 5 summers from 2000-2004 in the '71 and it never missed a beat. It arrived at my house 6 days after ordering it, additional bell housing, clutch/pressure plate assy, etc...... and on top of it, saved myself $2200. The car is going back together this fall.
I feel sorry for all the people that got or are getting suckered into paying $6000 for a transmission. My T56 Magnum didn't even cost that much. The new Tremec TKX 5-speed is $2795 and is in a much smaller case so you don't have to cut the trans tunnel. Tremec will be around forever and have an enormous dealer and parts network.
Guys, do some research and save some money. Get a better product faster.
Tremec TKX TREMEC, the leading manufacturer of manual transmissions and components, announces the release of the new TKX, a 5-speed RWD manual transmission developed solely for the aftermarket. “We listened to our customers, combined their suggestions with our OEM technology and strengthened our aftermarket line up with the addition of the TKX,” says Mike Kidd, aftermarket business unit manager at TREMEC. The all-new 5-speed, single overdrive manual transmission from TREMEC was designed, tested, and built specifically for the aftermarket.
For the development of the new transmission, TREMEC engineers took a forward-looking approach to finding the best and most efficient solution. This included universal packaging, excellent shifting performance, and extreme durability.
The three-piece aluminum housing provides outstanding structural stiffness (includes main case, intermediate plate and rear extension). Gaskets at all flanges simplify installation and eliminate fluid leaks. The transmission is designed for multiple to fit applications with three shifter locations and an overall compact, end-loaded design that provides clearance in most transmission tunnels without floor modifications. Separate GM and Ford case patterns and input configurations are available.
Internally, the TKX features a robust design with internal three-rail shift system and steel shift forks. All gears and shafts are made from special grade steel (ASTM 4615) providing increased torque carrying capacity, and a wide gear width increases gear life and a 600 lb/ft torque capacity, while at the same time, noise, vibration, and harshness (NVH) performance is optimized with a gear layout to best control stress levels. One of the key characteristics of the TKX transmission is its outstanding shift-ability at high RPM (up to 7,500) to match modern, high-performance engines. This was achieved by using multi-cone synchronizers and hybrid synchronizer rings made of sintered bronze and carbon. Additionally, a single overdrive reduces engine wear and fuel consumption for comfortable roadway driving, and the transmission os offered in multiple gear ratio configurations (See chart below). Connecting the transmission to the engine and driveshaft are a 26-spline input shaft and a 31-spline output shaft for added strength.
TREMEC has also equipped its TKX manual transmission with a high-performance short-throw billet aluminum shifter that isolates road noise, while providing clean, crisp shifts, and a built-in reverse light switch and cruise control safety switch provide additional functionality for street car applications.
