New! TCI® PRO-X™ Input Shafts Provide Ultimate In Strength For GM Powerglide Transmissions

Two new extreme duty input shafts handle up to 2500 hp applications

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

The PRO-X™ ringless design input shaft (Part #749603 ) replaces the load-limiting internal rings with a special bushing and enlarges the diameter of the shaft for increased strength. In addition, TCI® re-engineered 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 (Part #743510 ) for proper operation.

Hardened Input Shafts

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-350/400 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 the Turbo-350/400 transmission.
