The transmission is on its way out.You could drive the vehicle with the overdrive function turned off to buy some time.
No
yes it is, unless your in the mountains, going up a steep hill, or towing.
The overdrive should be switched off when you want to avoid unneccessary shifting. If you are driving on a hilly road, the vehicle will shift out of overdrive going uphill to maintain speed while pulling the vehicles weight up the hill, and shift into overdrive going down the hill to save fuel when additional engine power is not needed. When towing with an automatic transmission, the vehicle may tend to repeatedly shift in and out of overdrive due to the added weight. In scenerios such as these, you should turn off the overdrive to avoid the unneccesary shifting which puts more wear and tear on the transmission.
most of the time it saves gas but you should use low gear when towing or going down a steep hill
Not at all. Overdrive is for high rpm acceleration like quick on ramps and passing, or even going up a hill. In snow u want a lower rpm so u don't lose traction.
Overdrive is always on by default every time you turn on the engine, even if last time you drove you turned it off. Given that Mazda does this, I believe it is their intention to use overdrive all the time. However, there are times I would turn it off. This would be when going up and down small hills where the transmission has to constantly change gears. It has to downshift when going up hill, and upshift going down hill. To minimize how many times it has to go in and out of overdrive, I turn it off on those kind of drives. Also, when towing a heavy load, I recommend turning it off, since it is not designed for the extra load.
It depends on what you mean by slowing down....and how steep the hill is. It's a 5400 lb vehicle running with a 4.6 or 5.4 liter engine.
It is the giant hill at Expedition Everest in Animal Kingdom. It is 80 feet tall. When you go down the hill, it takes your picture. In my opinion, Expedition Everest is the best ride at Animal Kingdom.
If you are not towing anything for sure disengage the overdrive on an A/T. On a manual 5 speed put it in 4th, or 3rd, or 2nd, or even 1st gear depending on how steep the hill is and how fast you want to go.
It's normal for a vehicle to drop out of overdrive when it's under a severe load like going up hill or a lot of weight in it. That helps the engine to maintain speed and keeps the transmission from running hot. The ECM moniters the actions of the car and driver inputs and makes a decision automatically.
The overdrive is before the drive because as you ordinarly drive down the road your car automaticaly goes into overdive when you reach a certain speed. You use drive only when you are pulling a trailer or going up a large hill so it won't go into overdrive and put undo work on the transmission or motor. It is also a gas saving factor.
probaly a pin head hole in one of your wires check it in the dark and look for a arc
