my tuner did blue wire mod by cutting the solenoid pressure line and connected a resistor i believe It's called to the tcu. 3 weeks later my car in drive sometimes goes into 3 or 4th if i manually shift all gears, but always goes into first and second. this problem seems to occur only on the city streets but at high speeds it runs perfect. also, It's connected to my ecu so he could control line pressure based off of throttle position. either can u guys help me out? any idea
