What does a hard shift in all gears do?
If the shifting problem is a hard shift in all gears, it’ like the pressure control module inside the transmission that doesn’t control the fluid pressure correctly. The transmission computer puts it into default mode which shifts firmly to prevent any slippage. This resets when the engine is turned off for a minute or so.
Why is my mercury transmission shifting the wrong gears?
The TCM sends signals to the solenoid pack and into the electronic transmission solenoids controlling whichever gear is being shifted. The programming error is causing the wrong signals to be sent to the electronic solenoids, and the Mercury transmission is shifting the wrong gears.
What to do if your Mazda transmission is not shifting?

What happens when you reset the transmission shift points?
It is not going to make your shifting abnormal. If your gear shifts are abnormal you have something else going on. Resetting the transmission shift points makes the transmission the same as when the car is out of the factory. Within 30 driving cycles, the ECU will monitor your driving habits and adapt the shifting points to your driving style.

Why does my transmission sound like a bad belt?

Why is transmission shifting hard from 1st to 2nd ND?
When anyone of this sensors is bad it hard to shift gear. So if the sensors fail to receive and send the right signal readings, shifting problems can occur due to the wrong signal transmission. Transmission shifting hard from 1st to 2 nd could be as a result of an issue in the vehicle vacuum lines.
When does transmission go back to default mode?
It may not repeat until the trans fluid is hot enough that the pressure control module loses the ability to control the flow into the shift accumulator to control the application rate of the clutches as the transmission shifts, and transmission goes back into default mode.

Can a transmission shift late after a fluid change?
Only after the change did I find out that changing fluid after so many miles can be bad news. Now my transmission is shifting late and hitting the gear hard. I have checked the level while it was running on level ground and it was fine.
