When the car is just cruising along at approx.50+ MPH push the O/D button. You should feel the gears change higher and if you have an RPM guage then it should drop as well to fewer RPMs. This would be normal driving conditions. O/D will not kick in until the last regular gear (3rd or 4th depending on model)  had been shifted into. O/D automatically kicks out when slowing down and the transmission shifts to a lower gear. Thus the O/D has no function at slower speeds/gears and does not need to be shifted ( on or off ) except in the very first example given here.

Manual transmission


The short answer, yes. M46 models with the type J or P overdrive (depending on year and market) require a certain level of oil in the overdrive. Additionally, the overdrive is a lot like a standard automatic transmission with one gear range in theory of operation. Therefore, the hydraulic properties of said transmission do come into play here, line pressure, shifting pressure, accumulator and piston function all work together to engage or disengage the unit. Always ensure the unit is disengaged before downshifting and of course, shifting into low reverse.

1994 shift only when overdrive is off.


first thing to check is transmission oil level and quality. If that is fine than your looking at either a valve body problem (valve body is what controls the selection of gears) or possibly a problem with the bands on the planetary gear set, they can be tightened in certain models. However i dont think it is the bands.
Does the overdrive only engage 4th gear? or does it feel like the gear ratios are different between overdrive and normal before the problem happened? some overdrive buttons engage final gear and some do as much as change gear ratios like in a cvt (contantly variable transmission) and some just change the timing in the gear changes to provide more rpm/power.
My best guess is that the valve controlling the overdrive in the valve body has failed and therefor you dont get a response from the transmission (i.e no gear shifting when overdrive is selected)

What is the o/d button on top of automatic gear stick for please


Over Drive..... Generally speaking, overdrive (OD) is the highest gear in the transmission. Overdrive allows the engine to operate at a lower rpm for a given road speed. This allows the vehicle to achieve better fuel efficiency, and often quieter operation on the highway. When it is switched on, an automatic transmission can shift into overdrive mode after a certain speed is reached (usually 70+ km/h [43+ mph] depending on the load). When it is off, the automatic transmission shifting is limited to the lower gears. For an automatic transmission, it is almost always best to select overdrive and allow the transmission to control engagement of the overdrive. (It may be necessary to switch it off if the vehicle is being operated in a mountainous area or when towing a trailer.) With a manual transmission, overdrive should usually be selected when the average speed is above 70 km/h (approx. 43 mph).

No over drive


If you have a manual transmission model, check the wiring to the overdrive solenoid (M46,M47 transmission with type M overdrive) and check all fuses. This solenoid simply opens a check valve that allows the overdrive to function (DO NOT reverse the vehicle with the overdrive engaged or damage will result to the unit itself).
Automatic transmission models also have an overdrive override solenoid, bottom left side. If it is stuck in the override mode, check for shorted wiring to the solenoid. Also check the switch which can bind closed. If you can put a voltmeter on the wiring to the solenoid itself, check for voltage; if you have voltage and the switch is known good, the wiring is faulty. No voltage means the solenoid plunger is stuck down. Remove the solenoid and repair or replace it. In most cases replacement of a well-used item is better than repair.
All models: Always verify the condition of the wiring and connectors before condemning the unit. In most cases a voltmeter will rule out what the solenoid isn't doing. If you have voltage at the terminals on manual transmission models but no overdrive function, the solenoid has either seized or the coil has burned out. On automatic transmission models voltage at the terminals means the opposite: the solenoid will override overdrive and keep it in the third gear. No voltage for manual means no overdrive; no voltage on the terminals for automatic models means overdrive engages normally; if this is the case, replace the solenoid.
If, after all this checks out, on automatic models, this means that the transmission valve body has plugged up with deposits. For manual models, it means roughly the same (the overdrive is essentially a one-gear automatic transmission) and it also indicates that something is amiss with the hydraulic circuits, in both cases. Low line pressure can also cause this to happen in both types which means either the fluid is bad, the valve body is dirty, the screen is clogged or the main oil pump in the transmission (automatic models) is leaking. Always perform a thorough check before condemning either transmission type - they are conventional in design and very sturdy.
On AW-7x transmissions, no brake bands are used, therefore only clutch packs are employed. On the M46 and M47 manual models, the overdrive is a bolt on unit (type J or type M, depending on year). On the ZF series of automatic transmissions, the overdrive is integral to the transmission, being a true fourth gear. All models use a solenoid to control the upper gear range.
Note also that if you have the manual transmission, it may prove risky to rebuild it if you can beat the synchro by a quick change. Rebuilds offer up different wear surfaces to the case and can make a noisy transmission noisier.
Automatic models utilize clutch packs front to back. Band brakes were eliminated entirely, and when these start to fail the most noticeable problem is sloppy, hard shifting even after a fluid and screen job. The clutch wear surfaces decrease in friction holding and become thin. This implies loose clutches and this implies poor shift quality.
Always change the fluid completely (including the oil cooler, note it is thermostatically controlled) and clean the magnets of all debris. Introduce new oil into the system and test again.

The automatic transmission is stuck in 3 gear.


Definitely, there's a problem with your transmission. You are right, it is overheating. It is
caused by worn out part inside your transmission.
Have it checked by a qualified mechanic.

Transmission problem on 95 cutlass ciera


Overdrive has two important factors involving when and if it turns on besides being in the proper gear shift position. One is tthe car has to FIRST reach operating temps before it will engage the TCC ( torque converter clutch ). That could involve a faulty thermostat, or short distance drives, Second important factor WILL DISENGAGE WHEN STEPPING ON THE BRAKE PEDAL. A brake switch could be misadjusted , and without you stepping on the brake, the computer thinks you are and wont engage TCC. Hope this helps.

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.

1992 A4LD trans problems.


Sounds like the shift kit is warn out in the transmission. The overdrive line may not be able to provide enough hydrolic pressure to engage the gears to move the truck. When you switch to regualr drive, that line is able to build the hydrolic pressure to engage the gears. At a certian speed (for the transmission, certian hydrolic pressure) there is enough pressure to engage the gears in overdrive, but go below that, and you have to start in drive again. If this is the case, there is no easy fix for that and I recomend taking it to a transmission shop to have your shift kit examined. Opening up an automatic transmission requires specalized tools, clean shop enviroment, and knowlage more then the average back yard machanic has.

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.
