My '03 PT Cruiser has error code PO755 and the transmission shifts normally

Question

I replaced the trans solenoid pack about a week ago when it wouldn't shift out of 2nd gear. The check engine light went out and the transmission was shifting normally. The check engine light came on again today with error code PO755 but the transmission is shifting normally. Any suggestions

Answer 1

P0755 2-4 shift solenoid malfunction

P0755 can be set also when there is no free movement or heavy resistant on the wheel area if the vehicle is shifting normally check for any resistant to the wheels

 here a caliper broke and rub against the rim of the wheel setting a P0755
