Ford Type 9 transmission
Type 9 (also, Type N, T9, or T-9) is a gearbox from Ford that was used in Ford Capri 1.6, 2.0 1983 onwards, Capri 2.8 1982 onwards, Ford Sierra 1.6, 1.8, 2.0, Sierra XR4i and Sierra XR4x4 2.8 as well as the US market Merkur XR4Ti.
The Type 9 was Ford's first five speed, rear wheel drive gearbox and it's based on the four speed Type E gearbox. The fifth, or overdrive gear was added to the four speed gearbox by placing it in the extension housing or tailshaft housing. This made production easier and cheaper but effectively limited torque capacity to 200 lb. ft. or so.
The Type 9 is a popular choice for five speed conversions of older cars and also for kit car builders since it comes with a separate bell housing so it can be easily swapped around. The gearbox has a one inch diameter 23 spline input shaft and the main gear housing is cast iron with an cast aluminum tailshaft housing.
Overall the T-9 is an excellent transmission for vehicles with lower power levels and lighter weight. However in applications that require more power the T-9 is frequently replaced with the stronger Borg-Warner T-5 transmission.
