Generally, the THM250 was attached to small displacement engines. In 1976 this gearbox was taken out of production and was replaced by the light-duty THM200 transmission. However, the THM250 reemerged in 1979 as the THM250-C as a result of numerous issues withTHM200/200C. The 250C version had a reduced weight thanks to the use of a central gear shell applied the THM350, but with three holes to decrease flywheel mass and the low/reverse piston with eight notches.
