The first planetary train 29 comprises a sun 52 connected to the first turbine 33, planets 53 on a carrier 54 connected to the output wheel 55, and a ring gear 51 reacting through series one-way detents 56, 57 friction braked at 58. The second planetary train 30 comprises a ring gear 61 connected to the second turbine 34, planets 62 on a carrier 63 connected to the output wheel 55 via the carrier 54, and a sun-gear 60 reacting through the one-way detent 57. The third planetary train 31 comprises a sun 65 connected to the third turbine 35, planets 67 on a carrier 68 which may be friction braked at 69 or friction clutched at 71 to the sun 65 for train 31 lockup, and a ring gear 66 connected to the output wheel 55 via carriers 63, 54. A first reactor 36 reacts on a one-way detent 44 friction braked at 45; and a second reactor 37 reacts to the casing through a one-way detent 47. For forward drive brakes 45, 58 and clutch 71 are engaged whereupon firstly the turbine 33 drives the wheel 55 at reduced speed through the train 29; secondly the turbine 34 becomes effective for higher speed ratio drive through the train 30, the detent 56 releasing; thirdly the turbine 35 becomes effective to drive the output wheel 55 directly through the locked-up train 31, both detents 56, 57 releasing, until finally the converter coupling point is reached following the successive release of the reactors 36, 37. For reverse, the brakes 45 and 69 are engaged whereupon the forwardly rotating turbine 35 drives the ring gear 66 and thence the output wheel 55 in reverse at reduced ratio, through countershaft planets 67, the turbines 33, 34 being ineffective. In forward and reverse drive the brake 45 and hence the reactor 36 may be selectively released to allow an increase in the speed, and hence the power, of the engine for increased torque. The vehicle may be braked dynamically, in the torque converter, by engaging the clutch 71 and a brake 48 which latter arrests the turbine 33. The friction brakes and clutch are fluidpressure engaged.
