Replying to: sohjc (Mar 28, 2008 2:38 am) if you had the codes pulled at a garage there should be other codes included also? if someone used a autostore bought generic scanner to pull your dtc's you need to get the car scanned by a garage that has a better quality scanner you need it scanned immediately so you cant avert a transmission failure the P0300 code is a primary code for a misfire normally followed by another code P0301-P0312 the secondary code will tell you what cylinder the misfire has been seen by the pcm. afterthought: if you dont get the misfire corrected it could lead to restricted exhaust and catalytic converter failure another expensive repair |

I have a 2004 Aveo that had its engine replaced at 113,395 miles. The reason for the engine replacement was that a piece of the bracket on the timing belt pulley broke off and lodged between the pulley and the wall causing the belt to break and obviously all hell to break loose in the engine. My husband, who has worked in the automotive industry for 10 years (parts department) and is a self taught mechanic, decided that is was easier to replace the engine all together than to try and rebuild the old engine. He was able to find one for a decent price with only 24,000 miles on it and after about a week's worth of work, was able to swap out the engines (which any mechanic will tell you, is just about enough to make you lose your religion....). The car now runs, but won't shift into 4th gear. The check engine light is on (it starts off solid, then will begin to blink after about 5 mins of running) and the rpm's are high when started (about 3K) then goes back down to what I consider normal (about .5K). The codes we are getting are P0300, P0700, P1781, and U0401. I'm fairly certain there's a bulletin out about this and I may have to get the valves replaced, but I seem to be hearing from others that it doesn't necessarily fix the problem. Any suggestions would be appreciated?

| I have a 2007 Chevy Aveo LS 1.6L automatic. My check engine light came on about 2 weeks ago. I took it to Autozone to have it test coded. It came up with 2 codes. PO700 and PO705. First...PO700 is "Transmission Control System Malfunction"......and PO705 is "Transmission Range Sensor malfunction (PRNDL Input). I did some research and with opinions from others I decided to purchase a Nuetral/Park Switch from the dealership and replace that first. I just installed it today and it did make a difference in the shifting. Instead of kicking when I shift into "Drive", I now feel nothing at all.....just smoothness. OK....so I didnt really notice the kicking problem untill I replaced the switch.....well thats 1 problem fixed and 1 less thing to worry about.....but why is my check engine light still on? I disconnected the battery completely for about 15 minutes thinking that might reset the cars computer and turn the engine light off, but nope, its still on. Might there be still another problem? What is the "Transmission Range Sensor"?...and where is the "Transmission Control System"? I couldnt find any info on this sensor online. Someone please shed some light on this situation for me. Any help is greatly appreciated. | |

Replying to: generalelite (Sep 18, 2008 6:50 pm) "Transmission Range Sensor" , neutral saftey switch is not working or shift indicator switch is not working, you may not have backlights. The dealer people call it a prindle switch (prndl-park, reverse, neutral, drive and low) also called transmission range sensor. "Transmission Control System" PO700, there is a TSB out on that for the 2007 model. www-odi.nhtsa.dot.gov/recalls Hope this helps Yupper

Replying to: generalelite (Sep 18, 2008 6:50 pm) I just took my car out for a little cruise and waalaa. Its working like its spossed to. It doesnt stick in 1st gear anymore and the check engine light that was still on, is off now. I talked to a freind that I work with whos a manager for O'riely's Parts (Orielys is his main job) and he mentioned that some cars computer systems will do a self check every so often so I guess I just needed to drive it around a bit and let the car feel itself out after I repleaced the bad switch. As far as the sensor, Im thinking that the sensors are in the switch that I replaced so it solved the problem all together. This is the 1st repair Ive had to do on this car and man did I get lucky.( couldve also been my awesome mechanical skills...lol.) I found the problem, researched it, and fixed it all on the 1st try. I havent had an american car in quite a while, so jumping back in and succeeding was the greatest feeling ever. As I did my research on this issue I found minimal information.....Hope maybe this will help some1 else out. Outies. |

I THINK I read that the automatic transmission 'learns' how you drive when you first get your Aveo, and it adapts it shift points to the way you usually drive. Is that right? If that is true, is there a way to make it 'relearn' a new pattern? I am noticing lately, that since I have HAD to slow down even more, thanks to all the damn cops hiding in the bushes, earning their money! My transmission is not shifting at the points that I use to have them shift at. God knows I drive like an 'old woman' as it is, but now I have to drive even slower, especially in the mornings, with all these school zones and cops with radar! Can I pull out a chip or something, to make the transmission forget my old driving pattern and to relearn a new driving pattern? Or is it imprinted on my driving pattern and I am stuck with it shifting at the wrong speeds and hunting for the right gear?
