The Japanese company Aisin AW created the TF-80SC almost 15 years ago. The unit is intended for front-wheel and all-wheel drive vehicles with an east-west engine mounting. That is why the transmission is quite space effective – its length is a mere 358 mm. In order to have six gears in such limited space, the designers used the Lepelletier-type gearset (see “AKPPro” #3, p. 18). This transmission designed for the transfer of quite a high torque is installed in models of various vehicle classes – С (OpelAstra, Chevrolet Cruze), Е (Volvo S80), as well as CUVs (Mazda CX-7 and CX-9) and minivans, or multi-purpose vehicles (Renault Espace). These transmissions work with engines from 1.9 to 4.4 L, the torque limitation being 450 Nm.page46 Разборка
The absence of the reverse gear is often accompanied by kicks and jerks when downshifting during forward motion or at stops. Sometimes the situation is as follows: the reverse gear is present, but it engages with an effort, as well as the first gear. From our experience, there are two likely causes of this trouble – the clutch failure or the wear of the synchronizers. Let us consider both possibilities.page36 Разборка
