#72 of 134 Transmission Range Sensor Circuit Failure?
Sep 18, 2008 (6:50 pm)
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.

"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

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.

TY very much Yupper.....your right on the money. I managed to get everything up and running normally again. I replaced the Park/Neutral Switch and thats apparently what the problem was. The problem I was having was after I put the car in "Drive", the transmission wouldnt shift out of 1st gear. So what I had to do was stop, put the car back in Park, then back in Drive again and then it would work normally. After I replaced the switch I was still skeptical whether or not I had fixed the problem because the check engine light was still on. Shortly after I drove it around the light turned off so all is good. Thank god because I just bought this car like 7-8 months ago and my warranty expired at 36,000 miles and the car is at 38,000 miles. Just like a car to do that....start fallin apart after the warranty ends....lol. Thanks again.

Hi, I just came across your discussion over your issue regarding the park/neutral switch, my wife owns an 04 Aveo LS and it just started acting all stupid. Low and behold, her engine codes was 0700 and 1781. She said the car got stuck in first too, pretty much a similar situation you were in. My question is where is this switch located, and about how much was the switch? Her car also has the code for multiple missfiring too, but that's another story. Any help would be great.
#77 of 134 Will The Transmission 'Relearn' My Driving Pattern?
Oct 07, 2008 (5:18 pm)
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?

I have a 2007 chevy aveo with 20k miles that is having some transmission problems. I have a manual tran that makes a very loud rattling noise in 3rd-5th gear (you can hear with the music cranked to full) that started a few months ago.. It also feels like the transmission is getting loose. I brought my car into chevy to get it checked and they did not hear it, i guess they were deaf. And they said every thing is fine. I find that hard to bealive.
Does any one know whats wrong with the transmission and how i can fix it?

I seems i have the same problem. I brought my aveo in to chevy and they said every thing was fine.BS. And it has nothing to do with the temp. I lived in wisconsin before i moved to calif. I spent a winter in wisconsin were it would get -30 deg. It's grinding is as loud in calif as in wisconsin. I also bought new tires for winter driving and it did not help.
Do you have a manual transmission or an automatic?
I am also going to bring back into chevy and going to personally watch them check my transmission and take them for a drive. If they find anything i will send a post your way.
#80 of 134 2008 Avero - Hatchback Auto Transmission Problems
Nov 29, 2008 (10:58 am)
Bought my 2008 Aveo brand new and a few months later (about 12,000) the automatic transmission is now working right when cold. the car seemed to work fine in cold weather but now since it has gotten colder here in central Pennsylvania, the automatic transmission in the morning is not shifting right. It will go into 1st great fine and then into second, then when it gets near 3000 rpms it never shifts. The only way I get it to shift is to leave of the accelerator and let it fall back to 2000 rpms or a little less then I can feel it shift down. Then after that I depress the accelerator and then it goes back up to 3rd and then into 4th. After that it works fine. But it seems that when itís near freezing or below freezing I have this problem. I am not getting any check engine lights or any warning lights at all. Anyone have any ideas whatís going on?? Bad transmission??

If you still have the AVEO Have the dealer do a crankshaft sensor variation relearn on your car. Every time a major component is replaced (motor,trans. etc) you have to have this done.( From Alldata)
