It accommodates all the sensors, so neitherwiring nor plug-in contacts are necessary. Motion Resistance Power in relation to load is calculatedin order to detect motion resistance uphill grade, downhill grade, vehicleoperation with trailer in tow. Sixteen different gearshift combinationscan be generated with four Hall sensors: four gearshift combinations for therecognition of selector lever positionsP, R, N, D, two gearshift combinations which areregistered as intermediate positions P-R, R-N-D , ten gearshift combinations which arediagnosed as being faulty. The Transmission Control Module J217evaluates the actuation rate and angularposition of the accelerator pedal driverinput , as well as the road speed andvehicle acceleration vehicle operatingstate , and whether the vehicle is movingup or down a hill or on a level road vertical section of route. This toolkit comes with the universal pulley lifter, press plug sec. In the Tiptronic function, there are sixdefined shifting characteristics for manual gear selection. Noise from the engine running at idlespeed when the vehicle is stationary isreduced and much less pressure has tobe applied to the brake pedal to stopthe vehicle.
This alloy is highly corrosion resistant,easy to process and has a 17. The ring gear idles and rotates athalf engine speed in the direction ofengine rotation. At high engine speeds, the transmission oilin the pressure cylinder is subjected to highrotation-induced centrifugal forces, whichleads to a rise in pressure. For power transmission, only a smallnumber of cradle type pressure pieces arein mesh despite the high input torque. In an engine, torque flow is notintermittent but continuous.
A multitronic transmission in a car combines certain aspects of a manual transmission with the convenience of an automatic transmission. The quality of the tool is excellent and will perform to max potential. By activating the kickdown, the driversignals to the Transmission ControlModule J217 that maximum accelerationis required. In thisoperating mode, a slip speed speeddifferential of approximately 5 rpm to 20rpm is maintained between thetransmission input shaft and pulley set 1. Pulley sets 1 and 2 each have a separatepressure cylinder for pressing the taperpulleys as well as a separate variabledisplacement cylinder for transmissionratio adjustment.
The contents of this are not updated. The inner segment seals the pressurechamber off from the pinion. Assignment of Components The sun gear input is linked to thetransmission input shaft and the steelplates on the forward clutch. Ramp shell 1 is form-fitted to the outputgear of pulley set 1 output gear wheel ofauxiliary reduction gear step. The following functions are executed viaselector shaft: Actuation of the manual selector valve inthe hydraulic control module, i. Pressure Control Valve -1- for AutomaticTransmission N215 produces a controlpressure which controls the position of theclutch control valve depending on thecontrol current calculated by theTransmission Control Module J217.
PressureControl Valve -2- for AutomaticTransmission N216 produces a controlpressure for the hydraulic reduction valvewhich is almost proportional to thecontrol current. In the engine speed range up toapproximately 1800 rpm and at enginetorques up to approximately 162 lbs-ft 220 Nm , the clutch operates in what isknown as micro-slip mode. This informationis used for precision clutch torque control. The fault is stored and a substituteprogram enables continued operationof the vehicle with some restrictions. The replacement of 01J differential is a practically impossible task for repair services. The object, therefore, is to set the contactpressure of the taper pulleys as accuratelyand safely as possible according torequirements. A low level means: switch is open 0.
It allowsreduction ratios to be adjusted continuouslybetween the starting torque multiplicationratio and the final torque multiplication ratio. According tothis principle, the reduction ratio betweenthe lowest and highest ratios can becontrolled steplessly by means of a Variator. Click the icon to leave your comment. Fault indication: flashing For a table of gearshift combinations, please refer to the Repair Manual! Selective clutch pressure adaptation resultsin an input torque which causes the vehicleto creep. The control module is attached directly tothe hydraulic control module with bolts.
The dual-piston principle makes it possibleto change the transmission ratio veryquickly by applying a small amount ofpressure. Thetorque sensor piston serves to regulate thecontact pressure and houses torque sensorspaces 1 and 2. The direction of rotationis registered for thehill-holder function. The actual data are used for calculatingnew characteristics see Micro-SlipControl, page 21. The segments are pressedmore firmly against the pinion and ring gearas the pump pressure increases, whichcompensates for radial clearance.
This feature isparticularly useful on downhill gradesfor example, as the driver can determinethe engine braking effect by selectivedown-shifting. The Transmission Control Module J217can no longer identify selector leverposition N. The Solenoid Valve 1 N88 controls theclutch cooling valve and the safety valve. The dynamic control program calculates anominal transmission input speeddepending on conditions. All rights are reserved to make changes at anytime without notice.
Fault indication: inverted Transmission ControlModule J217 To protect the component parts of thetransmission, engine performance isreduced if the transmission oil temperatureexceeds approximately 293F 145C. The parking lock gear is permanentlyconnected to the drive pinion. After the kickdownfunction has been activated once, theaccelerator pedal need only be held in thefull-throttle position. The engine torque is transferredto the Variator by the torquesensor only. Axial sealing elements are used to sealthe pipe connections.
