I have an issue with this 03 Aztek, and can find no info on possible causes. Transmission will not shift into 1st gear while in D or manually shifting to 1st. It starts out in 2nd gear. Also having an issue where pressing on the brake pedal causes the idle RPM's to climb upwards of 3K rpm. Shutting off and restarting, it will drop to 1500, but again climb as the brake pedal is pumped. Not sure if or how these could be related, but,,.
