When this happens to mine, i will stop then put the car in idle. move the shifter to reverse then to first, then second gear, then into park. and then repeat. This fixes mine. It happeny s about every five thousand miles or so.

My 2000 Dodge Durango has no overdrive what do I do


Hi EVE , I would suggest you take it to a reputable ASE Certified repair shop ! Do you know what transmission you have there are three different ones for your vehicle along with three different engine possibility's ! It could be the switch or a solenoid in side the transmission or a wiring problem or even a control module problem !

OVERDRIVE OFF SWITCH

DESCRIPTION The overdrive OFF (control) switch is located in the shift lever arm.
OPERATION The switch is a momentary contact device that signals the PCM to toggle current status of the overdrive function. At key-on, overdrive operation is allowed. Pressing the switch once causes the overdrive OFF mode to be entered and the overdrive OFF switch lamp to be illuminated. Pressing the switch a second time causes normal overdrive operation to be restored and the overdrive lamp to be turned off. The overdrive OFF mode defaults to ON after the ignition switch is cycled OFF and ON. The normal position for the control switch is the ON position. The switch must be in this position to energize the solenoid and allow a 3-4 upshift. The control switch indicator light illuminates only when the overdrive switch is turned to the OFF position, or when illuminated by the transmission control module.

OVERDRIVE ELECTRICAL CONTROLS

The overdrive off switch, valve body solenoid, case connectors and related wiring can all be tested with a 12 volt test lamp or a volt/ohmmeter. Check continuity of each component when diagnosis indicates this is necessary. Refer to Group 8W, Wiring Diagrams, for component locations and circuit information.
Switch and solenoid continuity should be checked whenever the transmission fails to shift into fourth gear range.

How does an automatic transmission overdrive solenoid and part throttle unlock work


When you depress the throttle, the throttle sensor electronically tells the computer to take the transmission out of overdrive and when the throttle is released overdrive comes back on. When you depress the brake pedal, it also will go out of overdrive by a switch connected to the brake pedal with the brake light switch. Let off the brake pedal and goes back into overdrive once at speed.

Overdrive is not working


There are a couple of things to check on the M-46 with Type P overdrive (I think yours is a type P and not a type J):

1) Check the electrical connections from the switch on the top of the gearshift knob to the solenoid in the transmission with a VOM. Switch depressed - 12 VDC. Switch not depressed - 0 VDC. If OK - you are getting power to the solenoid that activates the overdrive.
2) Test the solenoid. Either use the switch on the top of the gearshift or use a local power source (12 VDC) wired to the solenoid. Listen for a light click. If you do not hear a click; the solenoid is probably defective. Test with a known good unit.
3) If the solenoid is working (and you are sure it is working) then check the oil level of the overdrive unit. These units use Dexron II/III (check your manual for the correct oil type) and ensure the oil level is correct.
4) These overdrive units are a lot like conventional automatic transmissions and are constructed as such. Consequently, the home mechanic should confine troubleshooting to the solenoid and correct oil level. The Type P units are slightly more durable than the earlier type J units but in either instance rely on fairly rigorous maintenance.

I have a 94 Jeep Grand Cherokee locks up in overdrive. I can turn off the overdrive and the transmission shifts beautifully. Not sluggish on take off at all. At a loss on what it could be any help would be...


Bad sensor. Cannot say exaclty which one, but I would assume the throttle position sensor. Could possibly be the switch on the shifter needs replacing, or the overdirve relay needs to be replaced.

Below is a method you can "self diagnose"


To get codes out of the Transmission Control Module (TCM). The lamp in the Overdrive OFF switch is used to signal the various flash codes. To view flash codes, proceed as follows:

  1. Turn ignition key ON-OFF-ON-OFF-ON finally leaving the key in the ON position. Leave the Overdrive OFF Switch in the normal overdrive (ON) position.
  2. Immediately begin counting the number of flashes displayed by the Overdrive OFF Switch indicator lamp.
  3. Flash codes will correspond to Powertrain Control Module codes in duration and spacing.
  4. A code 55 identifies the end of flash code transmission.
And the possible codes are:

  • 11 No Engine Speed Sensor Signal
  • 12 No Output Shaft Sensor Signal
  • 13 No Vehicle Speed Sensor Signal
  • 14 Governor Pressure Sensor Signal
  • 15 Throttle Position Signal
  • 16 Transmission Temperature Sensor
  • 17 Overdrive Off Switch Circuit
  • 18 System Voltage Out of Limits
  • 19 Standby Voltage Out of Limits
  • 21 Governor Pressure Solenoid Circuit
  • 22 3-4 Solenoid Circuit
  • 23 Torque Converter Clutch Circuit
  • 24 Overdrive Off Lamp Circuit
  • 25 EEPROM Checksum Error
  • 26 Governor Pressure Sensor Offset Drift
  • 55 End of Message
If you still get no codes, then we have to explore a mechanical problem inside the transmission. Possibly the overdrive solenoid not venting or a lower valve body malfunction.

best of luck and let us know?

I have a 1997 Kia Sportage (#KNAJA5278VA787759). The automatic transmission used to not shift into overdrive at 60 km/hr, but only after the engine was warm--after about 5 km of driving. The problem...


I had a simular problem.
Ended up changing the themastat and the gears changed into overdrive when the temp. got to normal running.
Be carefull that you get right thermastat though. You want one that reaches the normal working Temp as soon as possable.
Hope this helps.

1999 nissan frontier overdrive problem


juan: there is a cable which comes from the transmission to the throttle linkage. This is called the TV (throttle valve) cable. This is designed to work in conjunction with the position of the throttle. I'm sure you heard the term "KICK DOWN SWITCH". Well this essentially is doing the same thing. If the cable is out of adjustment, it will have a tendency to want to downshift into 3rd.
Even though overdrive is electrically actuated, it can be disengaged by the throttle position.
There is also a coolant temp sensor which keeps the transmission from shifting into overdrive until the coolant temperature reaches a certain point. The sensor tells the ECM to tell the Solenoid it's ok to supply a ground to it.
Your overdrive switch provides a ground to actuate the overdrive solenoid. Make sure the switch has a solid ground serving the circuit.
The torque converter solenoid picks up it's ground from the ECM.
Both solenoids are served by the same power source which is a switched circuit through the ignition.
I hope I have shed some new light on your problem and given you some new direction in which to look. I hope I have helped you resolve your problem. If not, I'll be watching and will be ready to offer more help if needed. ..mybunkey

2000 es300 lexus auto w overdrive button overdrive 4th gear not work


There isn't anything wrong with your car. This is perfectly normal. I have a 2000 ES300 as well as other people that I know and it operates in the same way. Overdrive doesn't mean the same thing for every car or transmission. In our case overdrive is simply a reference to the top gear which is 4th gear. When you switch overdrive off(which is depressing the button causing the O/D OFF dash light to illuminate,) the highest gear becomes 3rd because you turned 4th gear or overdrive off. The application scenario for this is usually mountainous terrain where a lot of uphill driving makes it more feasible not to up shift into 4th gear while ascending and descending. It will not switch back to overdrive or 4th gear until you re-engage it by turning the overdrive back on or repressing the button. Again, when the O/D OFF dash light is illuminated, overdrive which is 4th gear is off and the highest gear will then become 3rd. It will never shift into 4th gear while this light is illuminated or overdrive is off. When you press the button and the O/D OFF dash light is NOT illuminated overdrive is on and therefore it will shift into 4th gear as usual. This applies to all 97-2001 ES300's and probably any other car you drive tat exhibits this same type of change when overdrive is turned off.

1996 Corolla Auto Transmission problem


Hi. 2005 Corolla CE. It's normal. They tend to do this when upshifting form 1st to 2nd gear. No timing chain readjustment needed.

96 Corolla. Overdrive not working properly, if not engaging after 45mph constantly. If driving on the city, is normal, but not after 45mph, when the car is trying to engage overdrive in order to save gas and preserve the trans gears. If not able to get help at the dealership, find another one and explain them the situation.
