This has nothing to do with the transmission. Ford uses idle strategy in their software, to reset this disconnect the battery for 15 minutes, connect back and start the car in park, do not touch anything but the key when starting, let idle for 20 minutes on its own and do not touch brake pedal or anything else during this idle re-learn period. If this ...

Jerking and thumping when shifting through gears is an indication that you have bad either: bad engine mounts bad transmission mounts bad differential mounts bad axles a combination or all of the above Shifting into neutral does relieve the "tension", as you put it, but you need to care care of these issues. They can end up being costly.

From my experience, it depends on a vehicle and driving conditions: - Toyota Corolla, driving for 8 years and never had a problem with tranny when shifting D-N-D often. Need to be careful when RPM doesn't match speed: for example N-D shift at 0 with high RPM (when need to move, switch to Drive is forgotten and gas is pressed), it may jolt or even break, or ...

Breaking it down, Does sitting in Neutral put less wear on the transmission than Drive? Does the act of moving from D to N and then back to D put wear on the trans? And... (OP's overall question) do either of these "significantly" damage (i.e., cause to fail sooner than other parts) the transmission? So... Perhaps surprisingly, putting it in N wears ...

It could be argued that by putting the car in Park or Neutral, you are saving wear on the torque converter, which can be an expensive piece of equipment to replace. But I can't site any first-hand examples where that needed to be done, so again, the wear is likely negligible. :) I'd worry more about flushing your fluids and providing other regular ...

It shouldn't as stated above, but there are bushings and bearings that will get worn out, its probably better to just leave it in gear. Engineering Explained did a good review on this, so I recommend checking this out: Engineering Explained Automatic Transmission

No. Not by any significant or even measurable amount. Constantly using the shifter may, over time, wear the bushes and linkages prematurely but these parts are usually inexpensive and simple to replace. The transmission itself will be unaffected.

I don't know if they still have them, but back in the '60's they'd hold "economy contests" where the contestants would try to maximize economy on an oval track. The preferred method was to get a manual transmission car and lug it in high gear from 10 mph or so up to 25, then they'd push in the clutch and shut off the engine and coast back down to 10 mph, ...

Each car is a bit different but the highest efficiency for automatic transmission acceleration is usually at the point before the the transmission decides to automatically downshift. The data you should look for is called "brake specific fuel consumption". This may be a broad generalization, but your highest efficiency for normal gasoline cars with ...

The more throttle you apply the worse your gas mileage is going to be. If you want to absolutely maximize your gas mileage, use the minimum throttle possible. So accelerate only enough to just barely creep the speed upwards. On a hill, you would want a constant velocity and use terrain to your advantage. Basically put the car in neutral when going down a ...

I will answer the question in simple terms. Acceleration: CVT Does not have a gears and are usually single speed, so if you want to abruptly accelerate the CVT will not be as efficient as a manual transmission, the most common problem of CVT is the rubber-band effect where you push the accelerator and after a pause and acceleration increases suddenly. Ergo, ...

The difference comes down to the driver. While automatic racing gearboxes can beat a driver when it comes to performance, for the type of vehicle you describe, a manual can perform significantly higher than an automatic if the driver knows how to use it. But then if you really wanted high acceleration you would choose a different car. Maintenance is much ...

If there is no feeling of moving at all, not even that little lurch forward when things are working correctly, it sounds like your transmission is having a serious issue. Nothing says it's dead, too early for that yet. When you look at the transmission fluid, what color is it? Does it smell burnt? It should be a nice bright red, and not have the burnt ...

If the engine is capable of breathing mixture and spinning at the higher RPM, it should be producing more power than at lower RPM. Means it's likely getting eaten up somewhere in the drive train before it gets to the wheels, and the most likely candidate for that would be the torque converter as @Zaid suggested. Do you have a scanner for your car? Does the ...

I'd say the worst thing that can happen when overfilling an auto transmission is that the fluid in the pan will be whipped into foam by contact with the rotating parts. It will be evident by checking the fluid while running, it'll look like strawberry milkshake from the myriad air bubbles. These bubbles will compress and cause problems when the pressurized ...

Automatic transmissions are very susceptible to damage from overfill. This occurs because auto transmission fluid expands a lot (well, a lot more than engine oil, for instance). The problem it can create is blowing the seals, like where the torque converter rides. The seal itself is not expensive in and of itself, but getting to the seal can cost a lot. It ...

There's usually an inhibitor switch that stops the current going to the starter unless the transmission is in park - on older vehicles, a mechanical switch activated by the linkage from the gear selector, but on newer stuff I'd assume it is inside one of the many computers...

It turns out that the plastic end of the cable that connects the gear stick to the transmission broke, so the cable was loose. I had to unmount the plastic covers around the gear shift to find the problem. Our mechanic friend suggested a home built solution instead of having to replace the full cable, which would have required a lot more involvement. The ...
