Check the Throttle Cables

Changing the fluid solves plenty of transmission issues but if the problem of automatic transmission won`t shift into 3rd gear persists, the parts you should check are the throttle cables. A defective cable with excessive slack is likely to create issues with smooth shifting of the gears.

This kind of reaction is often a sign of low transmission fluid or a faulty transmission control solenoid. As you know, automatic transmissions use pressurized hydraulic fluid to change gears.
There could be a problem with the shifter cable or the shifter linkage from the transmission to the shifter. There also could be a problem with the slave cylinder, causing it to be hard to shift at times. A lot of times when the slave cylinder is going bad, it causes the car to be hard to shift at times.
Why the Transmission Won`t Shift Gears. One reason why an automatic transmission isn`t shifting into gear has to do with the fluid. If it`s not at the right level or the incorrect type has been used, then it`ll affect the gears. Another big reason has to do with the ECM possibly going bad.
Shift solenoid B allows the transmission to shift between 2nd and 3rd gear. When the powertrain control module (PCM) records code P0758, it indicates that the PCM is unable to detect the proper change in engine speed or increase in ground speed that should occur during a 2nd to 3rd gear shift.
Turn off your vehicle`s ignition and wait patiently for 5 to 10 seconds. Start the engine and allow it to idle for several seconds. Switch off the ignition and wait patiently for another 30 to 40 seconds. Repeat these steps 2 to 3 times in order to reset your vehicle`s transmission control module.
Shifting Problems– Clogged filters will make it hard to switch gears. If your car isn`t shifting smoothly, or if it hesitates or slips when you try to shift, you could have any number of transmission problems, so it`s best to have a professional look at it.
4L60E Transmission Loss of Third or Fourth Gear Problem

If you cannot shift into third or fourth gear, a worn-out clutch is typically the cause of a complete loss of third or fourth gear.

This may be a sign of low transmission fluid or a faulty transmission control solenoid. As you know, automatic transmissions use pressurized hydraulic fluid to change gears.
Rusting, power failure, irregular pressure, missing equipment, an incorrect amount of voltage or current, dirt stuck in the system and corrosion are some of the possible reasons why a solenoid valve may not properly close or open.
When the torque converter starts malfunctioning, you may feel shuddering and even slipping in overdrive. You usually notice your car shuddering because it feels like it`s vibrating. Your car will vibrate even when you`re not going very fast. The shuddering makes the car lag and is very noticeable.
Depending on the issue (low fluid is an easy DIY job), most transmission problems can only be properly diagnosed and repaired by a reputable mechanic. Most transmission repairs require specific tools and replacement parts to get them back up to speed.
For example, in some situations an oxygen sensor can cause poor shifting in your transmission – if the engine isn`t running correctly, the transmission control module may misinterpret when and where it`s supposed to be shifting, causing erratic behavior at the transmission.
A faulty crankshaft sensor is also used by the transmission as an input shaft speed sensor for the transmission to shift correctly. The sensor may affect shifting and also the way the engine runs. Your engine may also have went into failure mode if the crankshaft sensor is failing.
But a blown fuse No. 38 becomes a likely candidate causing a loss of power to the transmission solenoids.
Solenoid coil failure can be caused by a number of factors. Applying an incorrect voltage to the coil will cause it to fail and may cause the coil to burn out. Electrical surges or spikes may also damage the coil. Burnt out coils cannot be repaired and will need to be replaced.

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.

My 98’Saturn won’t shift out of 2nd gear. Could it be a shift solenoid for 3rd & 4th?
ANSWER : Hi there. Are there any lights on; check engine, transmission, etc.? A code retrieval may be helpful if there are any codes stored. Codes/data could lead a qualified technician in the right direction of diagnosis as this could be a shift solenoid, a shift valve, valve body, or even a turbine speed sensor circuit fault. When transmission problems like this arise always check the basics first; fluid level and condition, engine and transmission mounts, battery condition, ground points, and warning lights. A faulty battery may look ok, but a failed cell or low state of health is all it takes to vary the supply of voltage to the solenoids and sensors and create a host of problems. I suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several technicians available that can assist you with a car does not shift past second gear inspection.

My manual car won’t go into gear, it turns on and the clutch goes down perfectly fine. It happened after my gears grinded, the car
ANSWER : If the clutch mechanism is releasing properly, and the shift linkage is not malfunctioning, your transmission will have to be removed from the vehicle and inspected. Once a transmission has been removed from a vehicle, if the problem is a broken or worn part or parts, and the transmission has 100,000 miles or more, the most cost effective approach is to just simply rebuild the whole transmission. There are transmission rebuild kits that are sold just for this purpose. Rebuilding a transmission is no big deal and is indeed easier in many respects than rebuilding an engine. You can rebuild your transmission right in your own garage. You can NOT rebuild an engine in your own garage due to the highly specialized, and extremely costly, machine shop equipment required. Occasionally, mobile mechanics will take on a transmission rebuild job especially as once the mechanic removes the transmission from the vehicle, it is just simply a modular unit that can be easily transported to a mechanic’s shop and rebuilt right there and then returned to your vehicle. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

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.

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.

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.
