ok i have a s14 automatic and it has some shifting issues. i drive the car and it wont shift until 3-4k rpm i evergear except for 4th. and it also shifts hard. 1st to 2nd shifts like it has a shift kit. i had this for like a week. could it be a overdrive switch. the overdrive come on and off when i press the button.

Most likely a TPS harness connector problem. Check for oxidation on the pins.

i change the name because i couldn't get back in the forum, but i did a obd2 scan and its two sensor in the transmission.1) pressure control solenoid "A"2) transmission fluid temperture sensor "A" circuitcould this be the reason i can't shift in overdrive and the hard shifting into 1,2,3
