Hard shifting, worse with lower gears

I have recently encountered a problem with the transmission (automatic) in my 2009 Toyota Corolla. It worked well for the first 95,000 miles, but now the shifting between the lower gears is really slow. It started out just happening when accelerating uphill, but has gotten worse to the point where it nearly can’t shift from 2nd to 3rd. Is the only solution to replace the whole transmission? I would like to keep the car on the road as much as possible, so I don’t want it in the shop for weeks.
Experienced mechanics share their insights in answering this question :
There should be no need for you to have to replace your transmission yet. You should get a full diagnostic check from YourMechanic first before any part or component replacement. The problem you describe can be caused by a few different problems. For example, the throttle position sensor may be out of adjustment causing it to not follow throttle movement properly, which would not allow the engine to develop its power at the correct throttle position. Another issue may be a solenoid in the transmission that is causing the lack of or a delayed shift. I would first recommend having YourMechanic come to you to do a computer diagnostic check to verify the proper operation of the engine, the engine’s sensors, the transmission, the transmission’s sensors and its solenoids. The technician can determine your transmission shift problem causes and quote the needed repairs for you.

Transmission Fluid Low or Poor Condition – Vehicles low on transmission fluid or that are operating with worn out or contaminated fluid are likely to experience hard shift conditions. Lack of adequate lubrication within the transmission can cause several problems, including hard shifting.
Low fluid can lead to a transmission that shifts hard. It`s important to find out why the fluid is low and fix any problems. It could be a leaky seal or other mechanical defect. Otherwise, adding new fluid won`t ultimately solve the problem.
Oftentimes, hard shifting can occur when you fail to change transmission fluid at the recommended interval. In the event that your transmission fluid gets low or dirty, your vehicle`s ability to shift could become compromised.
Such problems aren`t hard to spot. 2022 Toyota Corolla transmission problems can show up as shifting delays, grinding or jumping during acceleration, the car shaking on the road, or whistling noises and a burning smell coming from under the hood.
The Vehicle Speed Sensor measures vehicle speed. When it fails the transmission can stop shifting or shift late and harsh. A bad VSS may also inhibit overdrive and the converter clutch.
You may also have intermittent problems with the transmission shift solenoid, which will cause shifting problems. This can cause hard shifting or shiftings at too low or too high RPM, for example.
A damaged fin or bearing in the torque converter can cause hesitation in the transmission shifting, or the transmission to slip out of gear entirely. This is because the engine torque is not being efficiently converted into the hydraulic pressure needed to shift gears within the transmission.
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.

the most relevant questions and answers related to your specific issue

I got sound when I shift to 3rd gear and it’s get hard to put shift to second gear when car is in 3rd gear.
ANSWER : Hello. It sounds as though the synchronizers in the transmission, which are used to adjust transmission internal gear speed when upshifting or downshifting are possibly worn out or you are shifting a bit too fast. It is also possible that the clutch is not releasing fully when you press the clutch pedal. In some conditions, utilizing synthetic gear oil in the transmission can help the quality of gear shifting. If the clutch is not fully releasing an inspection of the clutch hydraulics is a good idea. I would recommend having an inspection of the hard shift completed 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 for repairs.

Hard shifting between lower gears
ANSWER : Hey there, thanks for writing in about your 2000 Saturn LS2. This sounds like a common symptom of a transmission valve body not working correctly. The valve body of a transmission directs traffic when it comes to hydraulic fluid in the transmission. It’s function is to shift fluid to certain areas inside the transmission, which then activates the different clutches to move to the next gear. When the valve body loses pressure or is not functioning correctly, the shifting from one gear to the next may become erratic or irregular. This can be a difficult problem to detect. I recommend having an expert from YourMechanic come to you in order to diagnose and repair the hard shifting issue.

My gear shift doesn’t shift to any other gear its stuck on neutral. I open the gear assembly and I can pull a lever which allows me to move it.
ANSWER : Hi there. The shifter interlock solenoid is not working and needs replaced. The shifter interlock solenoid makes the shifter lock in place so it does not move if you accidentally move it into another gear. If you need further assistance with your shifter not working, then seek out a professional, such as one from Your Mechanic, to help you.

Im having a really hard time shifting into any gear other than 5th in my truck. I have to use alot of force to shift into gear.
ANSWER : You need to have the hydraulic clutch checked to see if it is disengaging the clutch as it should. The clutch is not disengaging and is the cause of the gears not being able to be shifted. You may have a bad clutch or clutch hydraulic system.

Won’t shift past 2nd gear . It drives normal to 2nd gear but wont shift into 3r – 2000 Ford F150 4×4
ANSWER : Hello – I don’t think this is related to switching back to 2WD per se. There is a shift position sensor on the side of the transmission, and it’s possible that the snow activity caused moisture and/or dirt to get into the sensor. I would recommend a transmission 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.

Loose gearbox that won’t find 2nd or 5th gear, sometimes hard to differentiate between 1st and 3rd.
ANSWER : There are a couple of possibilities. The first thing that comes to mind is of course the shifter itself. There is a nylon ball and socket joint at the base of the gearshift lever that sometimes falls apart, making the feel of the shifter very vague. Additionally, there are links to the transmission shift linkage that involve nylon bushings and joints that can fall apart. Both problems are very common on your car. The other less common possibility is that you have a bad motor mount that is allowing the transmission to move around too much when you try to shift gears. either way, it’s not a big deal to fix, and probably won’t require expensive transmission work. If you contact Your Mechanic, they can send a technician to your home or office to check out you shifting issue and let you know what repairs it will take to correct it.

The car doesn’t shift into first gear while it works fine in reverse
ANSWER : The problem could be that the internal transmission pump is weak, or the transmission clutch seals are leaking. It sounds like the transmission will need an overhaul.

I recommend having a transmission mechanic test the pressures and diagnose the problems to verify whether you need an overhaul with a new torque convertor.
