We offer three different T-10 transmissions. All are built for Chevy applications, so are modified for use with Ford bellhousings. A conversion pilot bearing must be used for Ford cranks. The Stock version has a provision for a speedo. The Modified (racing) version features rollerized 1st, 2nd and 3rd gears, a special mainshaft, hubs, bearings, but NO provision for a speedo. T-10 features Dog-ring type design for clutchless operation with lightening speed, using special 9310 nickel alloy gears. These are race-proven for reliability under the most extreme conditions. (Optional gun-drilled mainshaft and REM treatment available.)
