2004 Chevrolet Aveo Q&A

2004 Chevrolet Aveo Question: Why is my 2004 Chevy Aveo5 only going into 1st and 2nd gear, won't go in 3/4th?

We have a 2004 Chevy Aveo5 Hatchback automatic, 1.6L, she goes into first and second gear then revs up and don't go into third or 4th gear. Had a DTC scan done and these codes came up: P0106, P0452, P0122, P1122, and P0700. -
Answer 1
Have throttle position sensor and map sensor + their circuits tested as it has a big influence on trans. shift. Also have the TCM itself scanned for specific codes other than PO700. -

we have a TPS ordered, just waiting for it to come in...would those Throttle Position Sensor codes cause or have something to do with the P0700 code??? TPS came today, new one put on....still the same problem!!!! Forgot to mention also, when you first start the car the rpm's rev up and down without touching the gas pedal... -

Comment 1
Can you remove just the TCM to have tested/scanned for other codes? -
