Will a transmission filter keep your vehicle from moving when in gear
My car has 144444 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
The issue is much more likely to be engine related and, if so, can be diagnosed readily by a mobile mechanic with an appropriate real time scanner. With regard to the transmission filter, if the filter were clogged enough to reduce hydraulic pressure in the transmission, the clutches wouldn’t stay engaged and you would have no movement at all rather than no acceleration.
Slow acceleration has a variety of causes. Fuel injectors can become clogged over time as the tiny passages become clogged. When an injector is clogged it can degrade the performance of the vehicle and the car may accelerate slowly or feel that it does not have enough power. Other symptoms include a rough idle, a vehicle that is hard to start and a decrease in fuel efficiency. A defective fuel pump will not supply enough fuel to the injectors. This can cause the vehicle to accelerate slowly, or even sputter and stall, especially at high speeds. A clogged fuel filter can also restrict the amount of fuel that reaches the injectors. A dirty mass airflow sensor can cause the wrong data to be be sent to the computer. A slow accelerating car is the result of this incorrect data. It may also trigger the Check Engine light. Other causes of poor acceleration are vacuum leaks, a defective throttle position sensor and a defective idle air control valve. To get the underlying cause of the problem resolved promptly, you can request an engine diagnostic for slow acceleration. The responding certified mechanic will get this taken care of for you.

How to Identify and Fix Common car Problems ?

If your engine revs up as you press down on the gas but your vehicle doesn`t accelerate as much as you`d expect, you may be dealing with transmission slipping. If you`ve ever tried to accelerate on ice, where your engine revs but your vehicle goes nowhere, you know the feeling.
When you press down the accelerator pedal and get minimal output, it could mean you have a problem with your fuel system. The most probable issue is a clogged fuel filter. Your fuel filter works to ensure that dirt and debris do not get into the fuel system.
A vehicle`s acceleration problems could arise from a number of different issues. These include, but are not limited to, a dirty air filter, low fuel pressure, or clogged fuel injectors. A problem with the mass airflow sensor, throttle position sensor, or engine speed sensor can also cause a car to accelerate slowly.
Vehicles with higher RPMs require more fuel, making the engine overwork. If your car has an internal problem that makes it idle higher, it might have a higher RPM that jumps when you try accelerating.
The reason it will not go over 2500 rpm is because the computer is in limp mode. This mode is for when the computer has a failure in it. Limp mode will trigger if there is an issue with one of the vehicle`s systems that the manufacturer suspects would cause major problems.
If your accelerator were to stick it would most likely be caused by a floor mat or other object getting jammed under the gas pedal. This could obviously be avoided by keeping your vehicle clear of clutter and making sure floor mats are properly fixed in place.
Cadillac DeVille VIII DHS Specs. With a maximum top speed of 112 mph (180 km/h), a curb weight of 3977 lbs (1804 kgs), the DeVille VIII DHS has a naturally-aspirated V 8 cylinder engine, Petrol motor.
The DeVille comes with the superb Northstar V8 engine. This engine develops 275 horsepower in the standard DeVille and 300 horsepower for the DHS and DTS.
The 2022 Cadillac CT5-V Blackwing is the ultimate performance king from Cadillac, which is currently on sale in the U.S. With a price tag of $83,995, the CT5-V Blackwing is powered by a 6.2-liter supercharged V8 monster. As standard, the CT5-V Blackwing offers 668 hp and 659 lb-ft of torque.
You will feel a loss in power while accelerating and at times intermittent jerks. To solve this issue find the fuel filter located in the engine bay or near the fuel tank in your car`s trunk. If the fuel filter is clogged replace it if you have the skills to do so or get it changed at your local mechanic shop.
Rough starts, hesitation and poor acceleration are all common symptoms of a bad spark plug. If a spark plug or multiple spark plugs are faulty, they will have trouble creating the spark that causes the ignition process in your vehicle.
Worn Transmission Fluid (Automatic Transmission)
Over time, the transmission fluid gathers dirt and grime. This can cause the engine to run roughly, stall or fail to accelerate when you press down on the gas pedal. You may need to have a transmission fluid change before more damage is done.
Fuel Filter Clogging Another reason for your car not accelerating on high RPMs, regardless of high RPMs or not, is a dirty or even clogged fuel filter. Fuel filters are installed in a car`s fuel system to filter out the dirt and the gunk in fuel.
The most common problem is a faulty fuse. In modern vehicles, engine idle speed is most often controlled by the idle air control (IAC) motor. This can be impacted by bad fuses in many different electronic systems in your car. Next, your high idling could be caused by a computer malfunction.

My car will not start Intermittently. I purchased a new battery 2 weeks ago and yesterday the car wouldn’t start. Got a jump and
ANSWER : The issue you are having is probably due to an intermittent fault in the starter motor itself or a deficiency in the starter electrical circuit, for example a large voltage drop due to a poor ground or a high resistance connection. These issues can be readily diagnosed and resolved on a mobile basis if you request a hard starting diagnostic. If you request that diagnostic, the responding certified mechanic will get this resolved for you promptly. Based on Toyota’s Factory Service Manual, the battery should not be disconnected if the vehicle engine is running. The battery acts as a large resistive voltage sink and consequently taking the battery out of the circuit, while the alternator is still running, can create a voltage spike on the car’s electrical system which is not good for voltage sensitive components such as the engine computer.

Push start will not start on a 2012 Dodge Journey after hooking up subwoofers and amp car did start after hookup but never started
ANSWER : Hi there. Unfortunately, we’re unable to offer technical assistance when aftermarket components or electrical upgrades are installed, as there are simply too many different things that could be causing your ignition problem. I would recommend contacting a local audio visual installation company or local automotive shop that completes electrical repairs to get some ideas, or purchase a service and repair manual for your Dodge to review the relay schematic to determine which ones you need to check and replace. This video might help you learn how to check for damaged relays – so you might want to watch it.
I put the wrong key in my car and a few weeks later my car just shut down and it will not start I believe it’s the computer but…
ANSWER : Hi there. What had happened is the wrong key set the security to the vehicle. This is to prevent the vehicle from starting with the wrong keys. Try removing the battery cables (+) and (-) for 13 minutes. During that time, put the original key in the ignition and turn it on. Activate everything in the car even though there is no power. Then remove the key and hook up the battery cables. The computer should have reset and reset the security. If the security is still being tripped, then I recommend seeking out a professional, such as one from Your Mechanic, to help you
After you sit with the car running, the car starts smoking and eventually starts shaking
ANSWER : Hi, thanks for writing in. It all depends where the smoke is coming from. If it is from the exhaust then your engine be running rich and starting to foul out the spark plugs. Have the computer tested to see if any codes are present that could indicate what is causing the smoke. If you see smoke from the engine compartment then you may be running the engine hot due to low airflow over the radiator. Have the cooling fan checked to make sure it is running. If it is running and the vehicle has the AC running and the blower is on or near high then you may be using more energy than the alternator can keep up with. This can cause the radiator fan to not turn as fast as it should and let the temperature to rise if idled for long periods. If you would like help, consider having an expert automotive technician from YourMechanic come to your home or office to inspect and diagnose this issue for you, and make or suggest any repairs as needed.
My car will be starting perfect and when the gas tank gets lower it will start having problems .
ANSWER : Based on the information you gave, it sounds like a possible fuel starvation issue, caused by a partially blocked, in-tank fuel filter or a crack in the fuel pump housing. The remedy would be to replace the fuel pump assembly and filter. The overheating may be caused by several things, including a stuck thermostat, faulty water pump, or even a cracked head gasket. I suggest having a certified technician, like one from YourMechanic, inspect the relevant systems to pinpoint the cause of your vehicle’s hard starting issue and overheating problem.
My car is stutter starting and vibrating
ANSWER : Hi there:
Anytime a vehicle sits for extended periods of time, multiple components are compromised and may need to be replaced or properly serviced. However, what you just described in regards to the shop you took your Toyota is not uncommon. Most ’shops’ (especially chains) complete repairs by throwing parts at them to see if it works. What should be done, and what we offer at YourMechanic.com is to complete a inspection first to determine what’s causing these issues. If you’re having problems starting the Toyota, have one of our mobile mechanics complete a car is hard to start inspection first. This initial inspection will save you time and money in the short and long term; and ensure you have the right parts and service completed to fix your vehicle’s issues.
Map sensor car won’t start up good ?
ANSWER : Your MAP sensor is an important input for your computer. It helps determine the load on the engine to calculate the correct amount of fuel to inject. It sometimes takes a few seconds for the vehicle to realize that the sensor is not producing a good signal.
At that point, it will use other methods to determine the fuel rate, such as pre-programmed fuel maps, throttle position, etc. I would suggest replacing the MAP sensor and retesting. If you would like to have it checked first, a certified technician from YourMechanic will be able to scan your vehicle and test components to determine the root cause of your starting issue before making a repair.
