Pro-X Input Shafts

Any successful racer know, '' To finish first, you must first finish.'' That's the idea behind the two new TCI Pro-X Input Shafts for hardcore GM Powerflide race applications. These two input shafts, one for the standard Powerglide pump or TCI Gerotor pump 890-743500 and one for the TCI ringless Gerotor pump 890-743510 transmissions, eliminate input shaft breakage by incorporating unique proprietary construction material and a special heat-treated process. The Pro-X standard configuration input shaft 890-749602 is a direct replacement component able to handle up to 2000 hp applications.

The Pro-X Ringless design input shaft 890-749603 replaces the load-limiting internal rings with a special bushing and enlarges the diameter of the shaft for increased strength. In addition, TCI reengineered and improved the shaft's full cooler circuit flow for more efficient torque converter function as well as better lubrication, and as a result, it delivers better strength and durability over other types of ringless input shafts. Able to handle up to 2500+ hp applications, use of the TCI Ringless input shaft requires installation of a TCI Gerotor pump 890-743510 for proper operation.

Vaccu Melt 300 & Vasco 300

TCI offers input shafts made form aircraft quality Vaccu Melt 300 steel billet and Vasco 300 material. Engines producing over 800 horsepower need the Vasco 300 for maximum reliability.

The Turbo-spline shaft allows installation of a 30 spline Turbo-350/500 converter in your Powerglide. These shafts require some minor machining of the stator support to accommodate the included turbo support bushing. We also offer input shafts that will allow the use of a 17-spline Powerglide converter with a Turbo-350/400 transmission.
