Original 99/03 RX =Conventional 4speed automatic(3+Overdrive) straight gate PRND21 ; top to 3rd via overdrive switch on the side of the Lever. 04/09 U.K. 300 = Conventional 5 speed automatic with a staggered stepped gate marked PRNDS +- ;S being Sequential NOT Sport.... S acts as overdrive lockout and when on the move and will lock out 5th gear (top) You should always choose S when towing a trailer. In S you can manually go up and down the box from gear 1 to gear 5. RX 400H 06/09 Original Hybrid with a CVT gearbox. The gate is stepped again , but this time with PRNDB. B is for braking and can be used manually while in Drive to slow the vehicle and increase the recharge of the hybrid batteries. It should be used when descending a steep hill either solo or towing. The Prius had this style of gearbox from 2003..., you must remember to put the lever back into D when the road levels out again... the later RX 450H has a CVT but with artificially inserted stepping points providing a similar gate and Lever to the 2nd generation RX300 mentioned above. ; PRNDS with +- manual selection available, but the nature of a CVT design is infinitely variable gears. Incidentally the 450h CVT doesn’t use cones and belts/chains like other CVTs but uses a planetary gear and one of the Electric motors as a coupling to provide its drive!!! Very cool often misunderstood cars!
