Shifting delays are often caused by many things but most commonly due to poor maintenance or high mileage. Transmission fluid, in addition to acting as a coolant, keeps internal seals lubricated to help prevent hardening or wearing out.
Delayed shifting is often caused by valves sticking the valve body, which prevents shifts from happening when they should. On newer cars, which control shifts using a computer, the problem could lie in the shift solenoids that are used to trigger shifts.
Worn Out Clutch: Over time a clutch will wear out. The lifespan of a clutch can vary depending on the how the car is driven. Symptoms of a failing clutch not only include hard shifting but also a spongy feel to the clutch and a possible burning smell.
The easiest way to remove lag is by installing a device on your gas pedal called a throttle response controller. Throttle Response Controllers are blue tooth controlled, inexpensive, and make a big difference in immediate gas pedal response.
A Sluggish Transmission
If you experience shifting delays with an automatic or manual transmission, you could have a bad clutch that needs to be replaced. The clutch can wear out over time and become sluggish or even refuse to operate.
Automatic gearbox telltale signs include hesitation, slipping, or “trembling” during gear changes. Manuals are more likely to grind. Jerking and clunking noises are more likely to be caused by failing engine and transmission mounts.
What is the fix for a slipping transmission? It`s simple. Just pop the hood of your vehicle, locate the transmission switch, and change the setting from “SLIP” to “STABLE” . . . If only it were that easy.
In a network based on packet switching, transmission delay (or store-and-forward delay, also known as packetization delay or serialization delay) is the amount of time required to push all the packet`s bits into the wire. In other words, this is the delay caused by the data-rate of the link.
Transmission fluid should be checked at least twice each year. Low transmission fluid can cause a delay in shifting and could cause damage to the transmission, leading to expensive repairs.
Some 2003 Honda CR-V owners have reported experiencing a harsh shift from first to second gear when driving with an automatic transmission. This issue can be caused by a variety of factors, including a faulty transmission control module, a damaged transmission seal, or a malfunctioning shift solenoid.
Honda CR-V manual transmission issues were particularly prevalent in 1997, 1998, 1999 and 2000 models.
Transmission: If your car hesitates when accelerating, then this could be due to a transmission clutch slippage, which is usually caused by low or old transmission fluid. Other causes with your transmission could be an old transmission oil pump, damaged clutches, or a clutch solenoid failure.
1. At the top of all auto repair experts lists for causes of problematic transmissions is low transmission fluid. Usually caused by a leak somewhere in the system, low or contaminated fluid makes it nearly impossible for the transmission to automatically shift gears and run smoothly.
This one is a lot easier to diagnose than slipping gears because you can check it while the car is sitting still. Simply shift the car from park to reverse, or from park to drive, and observe what happens. If there`s a big clunk or the car seems like it`s lurching, this could be an early sign of transmission trouble.
Automatic transmissions that shift hard, jerk or shake during a shift change may mean your transmission fluid needs changed or fluid level is low. In manual transmission vehicles, abnormal gear shifts could indicate damaged gear synchros, worn clutches or other, more severe issues.
It defines transmission delay as the amount of time required to push all of the packet`s bits onto the link. It defines processing delay as “the time required to examine the packet`s header and determine where to direct the packet”.
Latency vs Delay
Propagation delay refers to the amount of time it takes for the first bit to travel over a link between sender and receiver, whereas network latency refers to the total amount of time it takes to send an entire message.
A shuddering transmission usually stems from issues with lack of holding by the clutches or bands due to wear or pressure issues. This could be caused by many things including dirty or low fluid, improper signals from the computer, an ill running engine, worn or damaged clutches, valve body issues and more.
Though changing transmission fluid can`t fix mechanical problems, it does make for smoother shifts and can extend the life of your transmission. And even when manufacturers recommend fluid change intervals of 150,000 miles under normal conditions, it may be a good idea to change it more frequently.
Queuing delay – time the packet spends in routing queues. Transmission delay – time it takes to push the packet`s bits onto the link.
Delay distortion: The velocity of propogation of a signal through a guided medium varies with frequencies; it is fast at the center of the frequency, but it falls off at the two edges of frequencies. Equalization techniques can be used to smooth out the delay distortion.
Example of Transmission Delay
Find the transmission delay if the bandwidth is 10 Mbps and the number of bytes in the packet is 3000. Ttrans =L / R = (3 × 8× 10–3)/10 = 0.0024 seconds or 2.4 milliseconds.
Delayed engagement is the result of an extended clutch fill time in transmissions having planetary gears and hydraulic shift valves. The torque converters used with these transmissions also maintain torque to the wheels during a sudden acceleration incident, making it harder to stop.

ANSWER : Hi there – your slow-shifting behavior is reported fairly often on this vehicle, with an internal transmission fluid pressure leak (linear solenoid gasket) a common culprit. You don’t mention your mileage, but I recommend a fluid and filter change – using Honda fluid and a transmission inspection, performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.
My issue is my car will not shift properly. And accelerates slowly.
ANSWER : It sounds like the problem is in the transmission seals. They are either leaking or have a bad apply plate seal on one or more of the clutches inside the transmission. You should have the transmission scanned and pressure tested to confirm any internal leaks of seals or clutch packs. The transmission will most likely need to be overhauled or replaced. If you’d like a second opinion on this, consider YourMechanic, as a certified technician can diagnose your loss of power and shifting issue firsthand.
Car jerks when accelerating in reverse & makes grinding noise. Is this a transmission or computer issue?
ANSWER : Hi there. Typically when you hear a grinding noise when you move forward or in reverse it’s usually an indication of a gear fault either in the transmission or another driveline component. If this occurs only when in reverse, it’s likely a damaged reverse gear. It is also possible that it’s a hydraulic fluid issue not supplying enough lubrication or pressure inside the lines to fully open the gear. I would recommend having a professional mechanic come to your location and complete a car is hard to shift inspection, so they can diagnose the source of your issue and recommend repairs that should resolve this problem.
Car shifts hard and rpms rev high on there own or car doesn’t shift at all, ABS and traction control lights are on also. 2005 Chevrolet Cobalt
ANSWER : Hi there – first task is to be sure the transmission fluid is at the proper level, and in good condition (more pink than black, and no burned smell). Low fluid, or dirty fluid, can cause lots of unexpected transmission behavior. The second task is to check for problem codes, whether the Check Engine light is illuminated or not. The possible problem we’re looking for here is a failing throttle position sensor – which interacts with the transmission controller and affects shifting behavior. I recommend a transmission inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.
Why is my car slow to accelerate when I press the gas pedal all of the way down in my 1993 Mitsubishi Eclipse
ANSWER : Hello. It sounds like you have a serious transmission issue. If the engine is revving and the vehicle is not moving then this is a sign that the transmission is slipping and needs to be replaced or rebuilt. If there is simply no power from the engine then it may be something else like a bad catalytic converter. It sounds like you need to have a transmission specialist check this out.
Car does not move when I step on the gas pedal
ANSWER : Hi there. From what you are explain it sounds like the throttle body is failing or it may be a sensor issue. Most of the time the failure is in the throttle body motor. I usually install a computer scan tool to be able to monitor the sensor signals and see if the issue is in the sensors or the throttle body. If you need some assistance with this, consider YourMechanic, as a certified mechanic can come to you to [diagnose why there is no throttle response] https://www.yourmechanic.com/services/loss-of-power-inspection
Car has trouble shifting.sometimes the "D" in the dashboad display will dissappear and the car will then rev to 3000 to 4500 rpm.
ANSWER : What you are describing may be a result of a faulty speed sensor, potentially low transmission fluid or a even a faulty transmission control solenoid. As your vehicle travels down the road, the computer analyzes data being sent by vehicle speed sensors and engine speed sensors. Based on this information, the Engine Control Unit (ECU), or the Transmission Control Unit (TCM), executes the appropriate upshifts and downshifts by sending a signal to one of several shift solenoids. These transmission solenoids have spring-loaded plungers inside them, which are wrapped with wire. When this coil of wire receives an electrical charge from the TCM / ECU, it causes these plungers to open, allowing transmission fluid to flow into the valve body and pressurize the desired clutches and bands. When this happens, the transmission changes gears and you continue down the road. The computer controls the transmission solenoid in several ways. If the vehicle is equipped with a dedicated Transmission Control Unit, it can open or close the hydraulic circuit using a direct 12v signal. In some cases, the Engine Control Unit (ECU) can control the solenoid’s plunger by turning the ground circuit on and off. When this is not working properly, this can cause a jerking reaction, a delay in shifting or in some cases may cause the transmission to hesitate in shifting gears. I would recommend having a professional from YourMechanic come to your location to diagnose and inspect your transmission.
My car is slow to start
ANSWER : Hi there. Typically what you are describing is an indication that a tune up service is due. As the vehicle’s ignition and fuel system components age, they will collect excessive levels of carbon deposits, which makes it more difficult to ignite the fuel / air mixture in the cylinder. This is why it takes a few seconds of cranking to actually fire up. A traditional tune up includes replacing the spark plugs, plug wires, distributor cap, rotor and coil packs. It also includes cleaning the fuel injectors, the throttle body, and possibly replacing mass air flow sensor. However, there could be other components that are damaged that are causing this issue; so before you replace any parts, I would recommend having one of our professional mobile mechanics come to your location and complete a car is hard to start inspection; so they can pinpoint the source of your issues and ensure the right repairs are made.
