Shifting your transmission automatically to higher and lower gears is an important function of a transmission. With a automatic transmission, there is a shift lever that moves in the housing and shifts gears.
When you need to go into a higher gear, the shift lever moves up until it clicks into place. This continues until you reach a lower gear, where it remains locked. When you want to change gears, such as in drive mode select or halt mode, you have to physically unlock the gearbox by removing the Shift Lever.
This can be difficult when trying to quickly shift out of Halt or drive mode without removing the wheel or car body.

Speed up
Another way to fix hard shifting automatic transmission is to change the gear pattern. You can do this by removing the shift lever, changing the gear pattern, and putting it back in.
Many automatic transmissions have a white piece along the center of the shaft that changes with each shift. This piece is called the pin.
When you remove the shift lever on a car, you can take out the pin so it moves faster. With more pins, there are more chances that it will work faster.
With this being used, do not buy a automatic transmission if there are not at least four pin holes in it. The best ones are small diameter ones so nothing passes through them.
If you have to have more than four pin holes, then he needs good strong shoulders for them to go through.
Hold the gear until it catches
Most breakers remedy this by telling the transmission to hold the gear until you release the shift knob. This is called hold-up and requires removing some sort of support from behind the transmission to accomplish.
How to remove support is dependent on how you hold the gear. With most models, you must use a crescent wrench or something similar to remove the support from behind the transmission.
Flush the transmission
When shifting into a higher gear, the transmission must be moving more metal through the gears. This is called flushting the gears.
When shifting into a lower gear, the clutch has to be releasing enough so the wheels can move. If the gears are moving then the clutch is releasing enough to let the wheels move.
If your transmission is holding or hard shifting, then you need to flush it. This can be a little tricky if you do not have a special flusher method as your car does not need to be disabled, it just needs to be cleaned.
A good way to fix this is to use a loom of some kind or buy some shift-proof shoes and put those on.
Have the seals replaced
When your transmission is hard shifting, the cause can be the Transmission Fluid. When the Transmission Fluid is too thick, it does not let enough momentum to the Transistors change gears.
This problematic fluid must be changed when this occurs. There are two places to change it-the flush cylinder head or transmission pan flushing. Neither one works on their own so they need to be replaced together.
The Flushes must be done at exactly the same time every time the transmission is taken out for maintenance, so no late night car fixing! Make sure you take your car to get this done at least once a year for good results.
Check the torque on the transmission bolt
If the wielder notices that the transmission doesn’t seem to want to shift into gear, they should check the torque on the transmission bolt.
A properly fitted transmission won’t need any additional torque to turn. When a driver puts too much force into their car, the transmission has to work harder to pull the bolts out and put them in place.
The procedure for checking the torque on a automatic is similar to that of a manual. The driver firstly uses a torque wrench to get a good and equal hold on both sides of the bolt. Then, they backs off their foot from applying pressure onto it to let it release. Finally, they applies some minimal force and see how much it releases!
If there is too much pressure applied for awhile, it can lead to break down or shifting problems.
Have the internal gears inspected
If the gears look fine, then try changing the transmission fluid. If the gears are moving fairly smoothly, there is probably no fluid inside of them.
If the internal gear movement is gritty or hard, then there is likely some fluid inside of it. If that is the case, then it must be changed out by a professional transmission fluid changeer.
Some transmissions require special fluids because of their use, such as gas stations selling Transmission Oil. Other transmissions do not and may cause your car to shift hard or not at all.
Change the transmission fluid
When the shift lever is in the first or second position, it is time to change the transmission fluid. This may be indicated by an odd smell or a slow, thick transmission fluid movement.
When the car is in drive, there are two types of fluid. One is used to clean and condition the gears, while the other protects and lubricates the gears.
Transmission grease protects moving parts from being damaged by falling oil or gravel. If this isn’t changed when new ownership takes possession of the vehicle, it can lead to hard shifting, poor driveline performance, and even a broken gearbox frame.
To fix hard shifting with an automatic transmission, you must replace the Transmission Grease.
Have a test done to check for electrical issues
If the transmission is not working properly, it may require a new electrical system. A healthy automatic transmission needs its signal passed from the engine to the actuator (stick) and then to the transmission.
The signal must be maintained until it becomes active in the transmission. When it becomes active, it relies on there being an adequate supply of electricity to operate it. This requires a professional check to make sure there is still electricity for the new system to work with.
Many shops do this once a car has been on the market for a few years and people are starting to look for them. If you have recently purchased your car, you may want to have a tech check it out!
This article will talk about how to fix hard shifting automatic transmissions so that you do not have to take your car in for another repair.
