A compact automatic transmission of the planetary type adapted for front wheel drive installations including a Ravigneaux gear set and four friction elements whereby 3-forward drive ratios and one reverse ratio may be established, and a first shaft is provided connected directly to the engine and a second shaft being connected to be driven through a hydraulic torque converter. Each of the shafts is connected to drive an element of the gear set whereby a partly hydraulic and partly mechanical drive is provided. In addition, only one friction element need be engaged for each of the ratios established by the transmission.
