Hello,
I have a 1994 toyota camry 4 cynlinder, my car wont shif gear until it reach 3,000 or higher rpm, i changed the transmission fluid and filter but still doing the same thing, can somebody tell me what is the problem before i bring my car to the dealer or mechanic so that i will know they are telling the truth.
Thank you kindly.

Does the high shift RPM problem occur with every gear?

Does the speedometer work OK? The speedometer sensor also tells the trans computer have fast the car is going.

Could also be the throttle position sensor (TPS) issue. This sensor tells the trans computer how open or closed the throttle is.

If you or a friend is mechanically minded, the engine and trans have built-in diagnostic systems that might narrow down the problem.

 

thank you for your quick response, it does from the first gear, from total stop, then before it change the to second gear, then when i release my foot from the accelerastor it will change, speedometer works fine, could you tell me where the TPS pls, to i have to bring it to mechanic for the diagnostic, thank you in advance.

 

Look in the engine compartment. Follow the large plastic air duct from large rectangle plastic air filter box to throttle body. TPS is attached to the side of throttle body that faces the firewall. The part is made of plastic and would have a electrical harness connected to it.

It's possible the TPS is bad, needs adjustment or perhaps faulty electrical connection.

Could be other issues, just an educated guess.

 

Thank you joey, I will ask my friend to replace it then i will let you know as soon as possible, take care and thank you for your help, by the way where are you located at? I'm here in Potomac Maryland?

 

The TPS can be tested with an ohm meter, it might also need adjustment.

Have someone check out the TPS first before replacing. Plus check for any computer trouble codes.
