Delay in shifting, rambling noise when accelerating
Hello. My car has an automatic transmission and lately it started malfunctioning when I try to accelerate. It would work fine on the startup and then there would be rattling noise upon acceleration. It seems that it cannot shift to second gear normally, but seems to have a delay in shifting into the following gear. I think the issue is becoming worse and it seems as if it would stall occasionally. The shifting into next gear is very sluggish with noticeable rambling sounds. It gathers some speed when it finally shifts. The performance improved for a few days after I had the fuel pump replaced
Experienced mechanics share their insights in answering this question :
Various items can cause similar symptoms to the ones you have described. The most common would be a bad fuel filter, transmission fault, torque converter issue, shift solenoid problem, low fuel pressure, or a failed fuel injector. All of these are potential contributors to the issues you are describing which may be either separate or related to each other. If you want to have these symptoms inspected firsthand, a professional from YourMechanic will be able to diagnose your shifting issue and rattling noise to let you know what repairs should be made.

If you hear a rattling noise when you are accelerating then this is definitely a friction problem. This could be a simple fix such as tightening or replacing your engines various belts. You can do a simple check by dropping some water on the belts and revving the engine.
One main reason why the automatic transmission in your car may not be shifting smoothly is the ECM is going bad. It is best to get this checked out by an experienced auto mechanic technician who understands the electrical system. Other indicators include bad connections within, or worn out sensors and faulty solenoids.
If your transmission makes a grinding noise when you shift gears, you are likely experiencing friction between gears due to insufficient transmission fluid, worn transmission linkage, maladjusted binding, or a “dragging clutch.” If you hear grinding sounds when shifting from neutral to any gear, you may be dealing with …
Loud squeaking or squealing noise while accelerating could mean there`s a problem with your engine belt. It could mean the belt`s loose or worn. Or it could mean that one of the belt`s pulleys is starting to fail. Loud rumbling noise when accelerating might suggest there`s a problem with your exhaust system.
Ultimately, a transmission cannot function properly without sufficient lubrication. If your car`s transmission is poorly lubricated, metal components inside of it will grind against one another. This can lead to a rattling sound as gears wear down inside the transmission.
Whining From Engine Problems
If your engine emits this noise every time you accelerate, it could be a problem linked to bearings, fluids, and the engine belt. It is best to have an expert check out these components under the hood.
Worn fluid can lead to hard shifts
The fluid`s frictional properties play a vital role in ensuring the clutch plates bind together properly and gear shifts occur seamlessly. Over time, the fluid`s frictional properties can degrade, leading to hard, jerky or inconsistent shifts.
Beware a shake, jerk or grind
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.
When this happens, this can be due to one of four issues with your car. The engine itself may be suffering damage to the valves, bearings, or pistons, which may be the very source of such noises. The exhaust system may also be experiencing similar damage with parts like the header pipe, muffler, or resonator.
Key Takeaway Rattling noises when accelerating can be caused by a number of issues, including damaged or worn-out suspension components, bad wheel bearings, low transmission fluid, loose heat shields, and faulty engine components.

The most common reasons a BMW 328i has a rattling noise are the ball joints, struts or strut mount, or a problem with the sway bar links.
It`s not usually a good idea to drive a long time after you discover the engine making noise for this reason. It`s going to cost around $500 to $1,500 to replace the timing chain or timing belt tensioner. Left alone, the timing belt could skip or break, causing your engine to not run due to engine failure.

Having delayed shifting issue with my car. It does it more when you accelerate fast. If you accelerate slow it shifts 2003 Honda CRV
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.

Grinding noise around differenial area
ANSWER : Hi there. If the noise started shortly after the repairs you completed, it is more than likely that you have left something loose inside or an internal component is not properly aligned. However, if the repairs were completed correctly, It is more than likely that you have damage to a wheel bearing. You might want to isolate the noise you are hearing or contact a local mechanic that can come to your location and help you diagnose the noise.

Chattering noises coming from transmission
ANSWER : Hello. From the symptoms you’ve described it would appear to me that there may be an issue with the clutch disc or perhaps flywheel.
If the contact surfaces of either are excessively worn it may cause intermittent chatter, as you are experiencing. If the clutch is still the original one than it may need to be replaced.
If you’d like a second opinion on this or would like to get this fixed, consider getting some help from a qualified mechanic who can diagnose the noise your car is making. Once this assessment is made an accurate repair can then performed.

Whining noise from transmission and difficulty in shifting
ANSWER : Hello. From what you describe it would appear that your vehicle has developed some sort of issue with the transmission, perhaps related to the hydraulic system, or with the transmission gears. If there is an issue with the vehicle’s hydraulic clutch system it may cause problems such as grinding or popping when putting the transmission into gear. The components to look at there would be the clutch master and slave cylinders. If the clutch appears to be engaging and disengaging properly then it may be possible that the issue is with the transmission, perhaps in the form of a bad throw out bearing, or worn transmission gears. Both of these could also cause a whining noise as well as difficulty changing gears if a problem occurs. I would also check the fluid levels for both the transmission and hydraulic clutch systems, as that could also cause similar symptoms. If you are unsure I would recommend having a professional technician, such as one from YourMechanic, come to your location to diagnose what may be causing your transmission issues.

A 500 Transmission is shifting harshly or delayed upon take off. There is no Check Engine or MIL light.
ANSWER : Hi there. Check the downshift solenoid on the transmission. It seems that the solenoid is sticking or not functioning correctly. I recommend servicing the transmission with changing the transmission oil and filter. If there is some dirt or gummy slush in the transmission, by changing the fluid can help make the downshift solenoid work. If you cannot get the transmission to stop suddenly downshifting, then I recommend seeking out a professional, such as one from Your Mechanic, to help you diagnose your transmission.

After shifting into gear, i can accelerate but then there is no power to accelerate.
ANSWER : Does it feel like the transmission is slipping? If you are leaning into the throttle and the engine speed is increasing, but it feels like the vehicle speed isn’t increasing as it should, it may be time for a new clutch. One the clutch is worn out, it can be difficult to drive the vehicle as there isn’t enough friction material left to keep the bind between the engine and transmission. Consider hiring an experienced technician like one from YourMechanic who can come out and take a closer inspection of the vehicles lack of power and offer a more personal diagnosis then estimate the proper repairs.
