Question about 2005 Jeep Liberty

1 Answer

Overdrive I was reading recently in "Men's Fitness Magazine", that if you have an automatic transmission, you should disable overdrive while driving at low speeds or around town. Anybody got any comments on this? Thanks!

Being automatic, your vehicle selects overdrive when conditions are correct. The programming within the computer is designed to do this, and adjusts other engine functions accordingly. If you disable the o/d, it is possible to gain a bit more performance but more often than not you will be prone to forgetting to switch it back on when its needed. Overall this will hurt your fuel consumption and cost you $. One exception is that on many jeeps, going uphill they tend to stay in o/d too long. Most times you can "downshift" out of o/d by lightly touching the brake pedal.
Simply put, leave well enough alone... You can save more fuel by anticipating stops and coasting, (foot off gas) when approaching a light that is or will shortly be red, and not accelerating hard off stops. Just because someone writes it does not mean it's true!!!

When need use overdrive


Since the truck has an automatic transmission, you drive in the overdrive position all the time, unless pulling or descending a steep hill.
The transmission can decide when overdrive is the right gear to be in.

The overdrive will only come into use when the transmission module reads the correct revs/ road speed ratio. Switch if off for heavy city traffic driving to improve economy when it moves up and down all the time. No it will not harm the transmission otherwise.

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.

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 D inside of an O is for overdrive. It is an automatic overdrive transmission. There isn't an overdrive button on it. If you want to disable the overdrive you have to shift down a gear.

Automatic gears


Honda transmissions,as well as most other overdrive transmissions,should be driven at all times in drive 4,or the overdrive position,with the exception of severe driving conditions,such as towing a load,extremely hilly terrain,or long uphill grades,the trans should be taken out of overdrive,and placed in the drive 3 position.This is to prevent the perpetual shifting back and forth of the trans from 3rd into 4th,back to 3rd,back to 4th,back to 3rd,that would eventually damage both the 3rd and 4th gear clutch discs and components.
