Spanner showing on dash when engine running vauxhall vectra c


VECTRA CAR WITH SPANNER WARNING LIGHT This Vauxhall Vectra car with spanner warning light illuminates or flashes yellow. Light will illuminate for around 3 seconds when the ignition is switched on. If the fault light illuminates whilst the engine is running, this signifies a fault within the engine or gearbox electronics system. The system will switch to emergency mode where fuel consumption may increase and the vehicles drivability reduced. A Vauxhall workshop must be consulted. If the light flashes whilst the engine is running, this signifies a fault within the electronic immobiliser system and the engine will not be able to be restarted.

How can I fix a Nissan liberty automatic not changing gears when it gets hot


Hi sad to say this gearbox requires valve body repairs ,replacement of dextron 3 ATF fluid and filter.clutches and friction plates should be checked replaced if worn.Torque converter should be checked out.If gearbox has electronic functions a diagnostic report should be done before stripping.A conventional auto gearbox pre 2000 model could be fitted with a external modulator switch causing present fault ,over powering the above mentioned faults.

Not sure when overdrive is on or off


Overdrive acts like a final gear. It's easily noticed if it is on or off when cruising at higher speeds, as when operating the switch you will notice the engine revs alternate between higher and lower rev ranges.
When the engine revs drop, then overdrive is on, and when they rise, then it is effectively off.

The overdrive function works just like any other gear in that it reduces the torque from the engine to the wheels, and allows the engine speed to drop. This isn't always beneficial when climbing hills or towing however, or when driving hard, as you may prefer that the gearbox wasn't always changing gear into overdrive, as overdrive reduces the torque from the engine as a means to increase fuel economy and reduce stress. It is for this reason that the overdrive can be disengaged, effectively reducing the number of gears in the gearbox which you have available to you.

So simply put, for most drivers, in most circumstances, they will not need to turn the overdrive off.

In answer to the light on/off, the majority of vehicles have overdrive in the 'OFF' position when the light is on. It's a reminder light (amber) that you likely aren't employing the best fuel saving technique.

What does gearbox malfunction mean if it comes on then goes off. it said gear box malfunction reduce power see saab dealer. said it 3 times in about 2 hours then it stopped. now doesnt say it. but never...


Hi Buckbird, Take the vehicle for a diagnostic scan. The signal means that he on board diagnostics have picked up a fault! Maybe the transmission oil is low. Reduce speed advises you to get to your dealer or diagnostic center at a low gentle speed. Regards Johngee10

Can low steering fluid cause mechanical problems


Problems associated with low power steering fluid…

Hard Vehicle Steering
A low power steering fluid level can often times cause a vehicle's steering to become hard and labored. Adequate amounts of power steering fluid are necessary to enable a vehicle's power steering system to function and operate at optimum levels. A lack of power steering fluid in a vehicle's power steering system reduces the amount of hydraulic fluid pressure necessary to efficiently operating the various parts of the entire power steering system. Power steering fluid supplies the fluid force needed to operate the power steering gears and to enable power steering gearbox operation. Low power steering fluid levels reduce this hydraulic pressure, which commonly results in hard vehicle steering.

Pump Noise
It is very common for a low power steering fluid level to cause significant power steering pump noise. An adequate amount of power steering fluid is required to ensure the proper function and longevity of a power steering pump unit, which is a belt-driven pump responsible for housing and circulating power steering pump fluid. A low level of power steering fluid results in increased power steering pump friction, heat, and wear, all of which can significantly reduce the operational life of the power steering pump while at the same time cause excessive power steering pump noise.

Fluid Boiling
Many times a low power steering fluid level can result in excessive heating of power steering fluid, a condition that can seriously degrade the fluid and cause it to boil. A low power steering fluid level results in less available fluid to both lubricate and cool a power steering pump unit. A lack of power steering pump lubrication and cooling leads to excessive heat being generated within the power steering pump unit itself, a condition that translates into the available level of power steering fluid becoming super-heated and degraded. When this happens it is common for the power steering fluid to boil and lose all of its lubricating and heat-reducing capabilities.

Gearbox Wear
The power steering gearbox is a set of gears within a vehicle's power steering system designed to facilitate movement of a vehicle's front wheels. The power steering gearbox is connected to the power steering pump by hydraulic fluid lines that deliver a constant supply of power steering fluid to the power steering gearbox. A low power steering fluid level, especially a chronic and severe low power steering fluid level, can lead to increased friction and wear within the power steering gearbox assembly, a condition that can significantly shorten the operational life of the power steering gearbox and negatively affect its operation

What is the function of the EH- gearbox switch on a 1994 BMW 525i series


The EH gearbox switch serves to communicate with the TCM (Trans Control Mod). In A mode, it tells the TCM to operate in the most economical shifting program. M mode is for manual shift. If you have a * instead of a M, it stands for winter mode. This mode causes the vehicle to start off in 2nd so that torque is reduced thus reducing wheel spin on slick surfaces. Of course, by shifting into 4 or 3 puts you into sport mode for a more spirited shift pattern.
