MY CAR IS NOT SHIFTING CORRECTLY? WHAT'S WRONG.?

1991 Toyota Corolla • 111,001 miles

Usually when it shifts into gear (automatic) my car, it's ok when it shifts til it don't gear in after it passed 25mph? Doesnt it gear in when it reach to 35mph on the dashboard?
Need help & results please thank you.

Ok. When you drive a automatic vehicle, it shifts on it natural way.
Example: There is A (P) = Park, (R) = Reverse, (N) = Neutral, &
(D) = Drive <---.
When you step on the gas pedal the transmission shifts Automatically. Similar to a Standard like: 1st Gear is 5mph then 2nd Gear is 15mph then 3rd is 25mph then 4th Gear is 35mph.
Do you get what I meant?
Do I have to adjust my (Idle) on my Distributor or Something?

I understand automatic shifting but I still don't get what you are trying to ask about.

Do I have to change my transmission fluid & filter? To make it run smoother for it to gear in properly? This the only simple way to type it out. If anything I will take/send a picture to make it clear to both of us.
Thanks.

Are you asking what you might be able to adjust (or repair), because you feel that your automatic transmission shifts into 4th gear too early (or, it is not going at a fast enough speed when it shifts)? Are you thinking that it should shift when you are going around 35mph (like a manual trans), but it shifts at 25mph instead?
I am no mechanic, so please excuse me if I am wrong. I am just trying to help, but it sounds like maybe the mechanic that was trying to help you, did not know "what" your actual "question" was.

There is no filter to replace. It uses a strainer and if this is clogged, it would mean the transmission is a gone case as well.

I still don't understand if you have a problem with the transmisison or not.

To: graphicgirl222,
Yes that is the kinda of question to my answer that I'm looking for. Its similar to a standard stick shift. Stays on 25mph like 3rd gear & don't shift on 4th gear @ 35mph. <--- This is the simple answer I'm looking for? What is wrong with it?

Also to: KHLow2008,
That answer paragraph is what I'm looking for.

Automatic transmission shifting are dependent on throttle opening and do not specifically up or down shift at any fixed point/speed.

There is a ttransmissionhrottle cable that if incorrectly adjusted would result in erratic shifting. If the accelerator cable is too loose, you would not be able to get the throttle cable to open as desired.

Thank you.
Do you have a diaphragm or a picture, that you could show/tell me where is that location at in my family vehicle? We gladly appreciate it. Thanks much.

Sorry for the delay. Seems notifiation of the reply slipped through.

The throttle cable is attached to the throttle body whereby you have one cable to the accelerator pedal and the other would lead to the transmission. If you remove the air cleaner hose, it would be easier to work on.
