Renault also applies the Quickshift in Twingo and Clio model passenger cars. The principal development with this robotized gearbox is the ability of the driver to override the automatic mode at any time in order to change gears without having to swap modes. Under heavy braking, the box shifts down two gears to increase engine braking and 2017 The covering of the spoiler might come loose and pieces of the tailgate glass may detach while driving. accident steering 1,325 Renault Twingo III (2014 2016) 11. The knuckle could consequently deteriorate affecting the steering of the. In automatic, six auto-adaptive parameters manages the five-speed transmission.įor example, the “kick down” function triggers instant downshift when the accelerator pedal is floored, while the “brake assistance” function anticipates downshifts under braking to profit from the slowing effects of engine braking and also engages the ideal gear for reacceleration. 2017 The durability of the front left steering knuckle may be insufficient. This is all done without lifting off the accelerator pedal. For example, if the driver flicks the lever back three times when travelling in fifth gear, the gearbox will automatically select second gear. RECAP Procedure To run fault finding on the vehicle computers, switch on the ignition. In manual mode, gear changes require a simple flick of the joystick type gear lever a forward flick (+) to change up and a rearward flick (-) to shift down. SEMIAUTOMATIC GEARBOX Fault finding - Introduction. The Quickshift gearbox allows drivers to select for automatic or manual modes simply by moving the gear lever knob to the left. It consists of different systems of hydraulic actuators (for releasing and engaging the clutch, and for changing gear) and an electric pump assembly which provides the energy needed for gearchanging. Some 2007 Renault Twingo GT 1.2 TCE may experience failing catalytic converters, excessive oil consumption,electrical connector problems, failed mass air flow sensors, and in some cases the engines may need some major mechanical repairs, even complete engine replacement These cars usually need to be replaced of the new engine, and the results. The gearchanging robot which carries out the changing process. The engine management computer, which, thanks to information supplied by the gearbox computer, correctly adjusts the engine torque output and speed by working through the fuel injection and ignition timing. It can also take into account such factors as the gradient of the road and the driving style of the driver. The gearbox computer is connected to the mode and gear selectors, the brake pedal switch and the engine management computer. The gearbox computer to control gearchanging. Three main elements control the Quickshift: It is also linked to other technologies such as the fuel-injection system and the electronic control system. The system requires control of engine torque output and speed during gearchanging, in order to synchronize clutch operation and optimize the speed of shifting. The hydraulic reservoir is full to the top.The Quickshift robotized gearbox is essentially a manual transmission modified with a module to support the automatic operation of the clutch and gearshifting. I am a mechanic by trade, is there anything i can do to test the robotic unit? I disconnected the battery overnight to see if that did anything, tried again. This time with the engine not running, if you try to select a gear it makes a slight noise, doesn't seem to go into gear, then the gearbox fault light illuminates. If you tried to select gears with the engine not running it would go through the gears, you could hear the robotics selecting the gears. I am saying that because at about 34k the slave cylinder failed, on that time it would try to select a gear, then flash the 'what gear its in number' to say it couldn't select that gear. I left it running for an hour or so to get warmed up, and then tried, it started working hit and miss, occasionally it selected a gear and drove, so the clutch/slave cylinder is ok. If you turn it off for 10 seconds or so and try again it just repeats it all again. When the engine is started, it does go into 'N', (as it should) but then if you try to select any gear, it just thinks about it for a few seconds, then doesn't do anything except the gearbox symbol light comes on. The gearbox symbol goes out after a second or two as normal. It says its in 1st when the ignition is turned on, but the 'A' for auto is not on like it always has done. It was working fine when parked up, went to use it after a week, and now it will not select any gears. I have a 2009 Trafic DCi150 with a quickshift box.
