A transmission module 1 has an input 3 which can be connected to a drive source, and an output 5 which can be connected to a differential. The transmission module 1 further has a clutch 7 and an epicyclic gearing 21 with three rotational members, of which a first rotational member 23 is connected to the clutch housing 9, a second rotational member 25 is connected to a brake 27 and a third rotational member 29 is coupled to the output 5. A transmission 31 also forms part of the transmission module 1. Between the clutch 7 and the epicyclic gearing 21 is located a partition 45 which is connected to the transmission housing 33 while a wet space 47 is formed between the partition and the transmission housing. The actuation cylinder 15 of the clutch, the operating cylinders 48 of the brake 27, as well as the oil pipes leading to it are fixed to the partition 45 as a result of which the actuation is arranged as a single module.
