I think something’s wrong with my transmission.

I believe something is wrong with my transmission. Occasionally, it jerks & it does this other thing where it makes this really loud noise and it almost feels as though the car is pulling itself back – that's the only way I know how to explain it. It's kind of like it stalls for a moment. I've noticed that this occurs more often when I'm in stop and go traffic, and continues until I'm done with that particular trip. It's like it triggers it.

My car has 120000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
This kind of reaction is often a sign of low transmission fluid or a faulty transmission control solenoid. Automatic transmissions use pressurized hydraulic fluid to change gears. Every time a gear change is required, the car’s computer activates a transmission solenoid, which directs transmission fluid into the valve body to engage the correct gear. When this is faulty or not working properly, this can cause a delay in gear shifting or in some cases cause the car to not shift at all. As you have indicated, this tends to happen more during stop and go traffic. The reason for this is that in stop and go traffic, the fluid pressure inside the transmission changes much more frequently. This type of problem is amplified any time the transmission is low on fluid creating a drop in hydraulic pressure. I would recommend having a professional from YourMechanic come to your location to diagnose and inspect your vehicle.

How to Identify and Fix Common car Problems ?

Transmission issues: Owners of 2004-2006 Maxima sedans complained about slipping and overheating automatic transmissions. This particular issue may lead to a destroyed transmission with symptoms such as rough shifting, poor acceleration, and hesitations between gears.
While other Nissan models, such as Altima, Sentra and Rogue, became known for their CVT transmission issues, drivers of Nissan Maxima cars have reported several recurring CVT transmission problems. These CVT issues include lurching, acceleration issues, vehicle overheating and premature transmission failure.
What problems does a Nissan Maxima have? Late-model Nissan Maximas have problems with leaking low-pressure air conditioning connections, failing ignition coils leading to check engine lights, and power steering pump leaks. However, very few of the Maxima`s problems are catastrophic.
transmission replacement can cost anywhere between $3,500 and $4,800. However, how much you actually pay depends on: Model year. Submodel.
Also utilized are Continuously Variable Valve Timing Control (CVTCS), variable induction system, a silent timing chain and electronically controlled throttle. All 2006 Maximas come equipped with a standard 5-speed electronically controlled automatic transmission with manual shift mode and gated shifter.
The average cost for Nissan Maxima Transmission Rebuild is $4464.
Which used Nissan Maxima model years are the best? The Maxima model years with the fewest owner complaints are 2014, 2013, 2012, and 2008. As a result, drivers who choose one of these model years tend to have a reasonably straightforward ownership experience.
In terms of performance, the 2020 Maxima is slightly more powerful. It has a larger engine capable of 112-HP more than the comparable Altima.
The Maxima is equipped with a 3.5L naturally aspirated engine that is mated with a CVT. The fullsize sedan takes only 5.7 seconds for a 0-60 acceleration and has a top speed of 135 MPH.
For 2007, the U.S. Maxima became available with a standard Xtronic CVT (Continuously Variable Transmission) (similar to the CVT found in the Nissan Murano) as the only transmission choice; a manual transmission was no longer offered; however the CVT featured a manual mode.
Such problems aren`t hard to spot. 2014 Nissan Maxima transmission problems can show up as shifting delays, grinding when accelerating, a feeling of shakiness, or a burning smell or whistling sounds coming from under the hood.

2013 Ford Focus Transmission Issue. Is it worth keeping the car?
ANSWER : Hi There,
This is a known issue in this generation Ford Focus and some Fiestas with the "Power Shift" transmission and there have been numerous recalls and lawsuits. Although, it is would be difficult to determine how much longer your transmission will last given the fact that you have many new parts, I would not recommend junking the car as it may still provide some valuable life left for you. I would recommend taking it to the dealer to see if these parts may be covered under the recall.

There is automatic transmission fluid in a manual transmission. Is it okay to leave or do I need manual transmission fluid?
ANSWER : This would depend on what the manufacturer recommends. Many manual transmissions do take automatic transmission fluid. If your transmission has ATF in it, it is very likely that it is supposed to have that in there. If not, it is likely that the transmission would not function properly with the wrong fluid. Many manual transmissions will also take engine oil as a lubricant. The best way to know for sure is to check your owner’s manual or call your local General Motors dealership to inquire.

Transmission fluid comes up out of the transmission vent tube attached to the transmission dipstick tube
ANSWER : Hi there. Fluid seepage out of the vent tube can sometimes be normal, but can also be caused by overfilling. Has a service been performed recently? Perform a fluid level and condition inspection by having the engine at idle, on a level surface, warmed up engine, and remove the dipstick and cleaning it with a shop towel. Reinsert the dipstick and fully remove to a horizontal position for inspection. Make sure the fluid is not milky, very dark, or has contamination. The level should be in the safe zone marked on the stick.

Have an inspection by a qualified technician determine if any problems truly do exist and provide you with some assurance. YourMechanic has several technicians available that can assist you with a transmission leak inspection and can perform a transmission fluid service if needed.

Kia Optima 2004 v6 LX new engine old transmission no problems before with transmission now my transmission is shifting a high rpm
ANSWER : Hi There,
This may be an issue related to the communication of the PCM and the TCM (Transmission control module). As you may know, the TCM relies on the PCM to transmit information related to RPM’s, which the TCM then uses to determine when to direct the transmission to shift. The transmission control module has various sensors such as vehicle speed sensors, wheel speed sensors, throttle position sensors, turbine speed sensor, and transmission fluid temperature sensors that all direct information to it in order for it to perform it’s function. Other functions controlled by the TCM are components such as a kick down switch, traction control system, and cruise control module. Any of these may also affect the way the transmission control module performs and controls the transmission and the shifting of your vehicle. I would suggest having a professional from Your Mechanic come to your location to properly diagnose your transmission problem.

Bad transmission 2003 Chevrolet Impala
ANSWER : Hi – first thing to check if for correct fluid level in the transmission. Having too much fluid will cause foaming, fluid being forced out the transmission dipstick/filler tube and other behavioral issues. It is also possible, given your mileage, that something has failed in the transmission, and creating high fluid temperature and/or pressure, causing the foaming and fluid loss. I recommend a transmission fluid leak inspection by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

Can too much transmission fluid cause speedometer malfunctions?
ANSWER : Hi there. In most cases when you overfill the transmission fluid it can cause excessive foaming of the fluid or possible internal component failure due to excessive pressure inside the hydraulic lines. Sensors like the speed sensors however are rarely impacted by this situation. However, in regards to the possibility of probability of this; I would say perhaps a 10% chance.

Transmission can’t shift, thinks it needs to be replaced
ANSWER : The best advise to help prolong the life of this transmission is to service it regularly. Make sure you also service the engine cooling system on a regular basis since the transmission cooler is in the radiator. If you are in a warm climate or tow on a regular basis, look into getting an additional external transmission cooler installed. The transmission will run cooler and have less chance of heat-related failures. I also recommend you have a check up on the transmission before any warranty expires. Service any new transmission for the first time at 20,000 miles and every 30,000 miles after that.
