First, make sure you have the right amount of tranny fluid in there. Not too much or too little.
Second, the gears are switched by solenoids found under the tranny pan. When some of them don't work right, you will get intermittent hard shifting, sometimes in one or two gears, or all of them.
A dealer scan tool may be able to figure out which ones are bad. You can do the job if you can get under the car and remove the fluid/pan with gasket, and replace the correct solenoid and seal.
Always check fuses. Some circuts share the same current, and one failed part can cause other problems.
Good Luck!

Transmission hard shifting between first an second gear only when this happens the tachometer goes erratic

You have a engine RPM sensor that is not working correctly. Computer thinks you have push gas pedal to the floor and is providing that type of shift. It may be the sensor attached to your gas pedal has worn out.

Hot weather auto transmission shifting problem

Often this kind of problem it is caused from faulty throttle position sensor, you find out by connecting a code reader to your car computer.
throttle position sensor tells to your transmission control module how you are using the throttle, so that the car automatic transmission can shift to right gear, when this is faulty often you have transmission faults related to engine rpms and temperature, this can explain a trans problem happening only when engine is hot.
In some case it is not the sensor, but the computer module controlling transmission that is faulty.
To find out cause for the problem you need to connect a code reader to transmission module and to main computer module (ECU).
The code reader will return fault codes that allow to locate the problem. this kind of job can be done at any qualified garage.

Shifts erratic

run the fault codes and look for TCM problem. Check fluid level and condition. Replace if brown and while the pan is off to clean the filter have the bands and clutch pack adjusted.

Is the car running good? If the motor isnt running right and is missing with no power it will cause the transmission to shift hard due to taking to long to shift, so it could just need a tune up

I experience some problem with my 2002 odyssey. the check engine is on and when it goes up from shift to shift, it does not go the upper speed easily. As if you put the speed at position 2 and you...

The first thing to do is to have someone check to see what code is tripping the check engine light. Most auto parts stores will do this for free. Check to make sure your transmission fluid is full, and clean. Sometimes a vehicle speed sensor can cause erratic transmission up shifting, but see what codes are tripped first

Hard Shift 1998 Chevy 1500

I need to know the codes so I can properly diagnois your problem. Here are a few tips though. Your electronics inside the transmission may be going out. You should start by changing the fluid and the filter. Let me know if there is a lot of metal or fiber shavings in the pan. Put new fluid in and clear your codes. See how it shifts and then let me know what is going on with it. Hope this helps.

This is a common problem on some GM cars. There is a pressure control valve in the side cover of the transmission that needs to be replaced. The transmission does not have to be rebuilt. You will need to get a side cover gasket also.
