    I must have stopped and turned the truck off five times to make it 2 miles home today! They really hated me at that stop light! Hehehe
  • Yes I have a 2006 chevy colorado i bought brand new and I hate it so bad, ive had so many problems including what you mentioned and it occured the same way i would back out of a driveway to leave and thenm go forward and the tires would lockup and actually squell so after finally having enough of it i brought it in and they replaced the rear end but only would do it if i aggreed to buy all four new tires. [non-permissible content removed] i was actually not there at the time my dad was and he agreed to buy the tires which i wouldnt have doen. Before this all soon after i purchased the truck i noticed a very loud clunk that still to this day happens every day when im just driving and let off the accelerator and then get on it again there is a loud and actually jerky feeling that happens and the dealer ship says this is normal but i am not stupid and i know that this is a very bad issue and now that my warranties up theres not much i can do. The lst time i brought it in to the dealership i told them ok well what im worried about is that later on after the warranty is up my trans is going to go out or something major and the whole time it could have been prevented or replaced earlier when i told them there is something wroong i actually went as far as to contact a high up chevy rep through alot of work but he did get back to me and told me when i brought the truck in to the dealership to have them call hima and he will get to the bottom of it but of course they wouldnt and just kept telling me theres nothing wrong. So they told me they would put a note in the system saying that i have been coming in for this issue and if it were to be that something does break and its linked to the noise and issue i presented to them they would still cover it after warranty which i really doubt they will. My advice dont buy a chevy and especially the piece of [non-permissible content removed] coloado. JUNK
  • I recently purchased a used 05 Colorado with I4 and 5 speed. I am having the problem getting it into reverse. The once every 5 times being normal is a load of @*!#$. I tried several times tonight to get reverse and couldn't. Drove into town (8 miles) and had to park behind a restaurant because they had no full through parking spaces. Couldn't get it into reverse there either. Putting it in first doesn't seem to help.

    This was an extremely clean low mileage truck and I wondered why anyone would trade it in. I think I now know.

    I am an ASE certified tech and grew up in my father's Chevy dealership. Our customers would never have accepted the "one out of five is normal" explanation, and no customer should have to.

    ........Think I heard something about GM in financial trouble. Hmmmmmmmmmm. Wonder why?

    You are one of many customers that have had problems with their Colarado/Canyon trucks. These trucks were an Isuzu design and unfortunately are poorly engineered. I have seen many low mileage Colarado/Canyons available on used car lots and I know why; many owners got rid of them because of the many problems they were having. May be you should do the same and look for another truck. Good luck.
  • Hi Forum, i have a problem with my transmission shifting out that last gear. The problem started about year or so ago. The problem occurs mostly in cold weather, or thats when i notice it most often. When I start off, the shifting is fine, then when it gets to that last gear, it hestitates for a long time before it shifts. The rpm hand is regestering above the #2 on the dash board, once the shift finally change the rpm hand falls back down on the #2. Also, when I get up my speed to pass another car, the rpm hand goes really high. I had the cam shaft actuator changed on it about a month ago. GMC want replace the recall for the Engine intake valve seat :mad: . At least the GMC company that I took it too want fix it. Any one has any advise on this? I think I'm gonna have the transmission fluid and filter change. haven't changed it sense i had the vehicle.
  • The problem you are experiencing is normal. The transmission will not shift out and lockup (4th) until the engine reaches a predetermined temperature. Usually about 8-10 minutes driving a normal speed. If you let the vehicle warm up to normal operating temperature before driving, this will not happen. By design, the downshift control operates such that it ensures the engine speed is high enough to prevent stallling when passing gear is actuated. Again this is normal and can only be changed by reprograming. Dealers either cannot or will not reprogram the computer. (Some after market shops are willing to do the reprograming when one buys their aftermarket chips.)

    Unless operated in a severe environment or heavy load (heavy trailer), transmission fluid should not need changing for at least 60K or 5 years. Check the color and smell. If it does not have a burned appearance or smell bad, it should be fine.

    I have a 2004 Chevy Colorado 5cyl 4WD with 110K miles and 2 weeks back noticed a small tranny fluid leak, not bad as I added a quart and still OK 2 weeks later. After washing may car I took it out and after about 2 minutes of running came to a stop light, when I started up I noticed a lack of power, almost like parking break was on but it wasn't. I could only get up to about 15 MPH and didn't noticed the RPM's up so first thought catalytic converter, OH YEAH, check engine light came on when tis all happened. I let it sit for a couple hours and now seems to be OK. I read the engine code and it was P0756 and what I could find on internet relates to tranny, possible shift solenoid. It's been fine since but reluctant to drive any distance. No slippage and shifting fine. From what I can tell the leak is from the pan gasket so that will be replaced. Anybody had a similar issue? Is the P0756 tranny related?

    hello i got the same code just recently and my colorado is a 2005 5cyl 4wd with 112k mile and it just happen to me on a trip that caused me to turn around wich was a nightmare coming back home epecially on the hwy...but code p0756 is your transmission solenoid ( T.C.C. ) because my check engine light came on the process and after i got back in town it started shifting fine but theres a loss of power beacuse i can stilll feel it as it goes up the hill it will take time to reach 70 mph... but other than that it shifts fine the transmission control solenoid is no more than 40 bucks at a autoparts store but its vendor direct...but good luck ...

    Thanks for the info...Was it the 3-2 solenoid? What I've been able to find is that there are 4 solenoids, 1-2, 2-3, 3-4 and 3-2. I had the tranny pan off and saw several but have not been able to determine which one is which. Also, the code chart notes it as the "B" solenoid but the part stores I have spoke to don't go by that. Since I cleared the code it has not come back on and seems to be shifting OK so don't know what to do, leave it alone or start replacing solenoids. I found then on line at RockAuto.com for about $15 to $25 depending on which one. According to ACDelco the solenoids for shifting 1 to 4 (3) are the same part and the 3-2 is different. When you had yours relaced did they notate the part#, and was it ACDelco.

    Well they didn't do that because they found out it was the cat that got clogged up and its making my muffler rattle bad now but am gonna go get my truck hopefully this weekend and take it to a transmission shop were they can pull the codes out because am still with the solenoid and solenoid b is the one i got two but so far i haven't looked myself and thats a real good price on the those solenoids normally auto zone only has them for 43 dollars but price may differ on states.. but i will let you know on that solenoid when i get an answer.... :)
  • gumbta2gumbta2 Posts: 7
    Keep me posted. I thought clogged cat at first but when I read the code that pointed me to solenoid. Good luck and hopefully isn't to costly. Suggestion, if you have the tranny pan off braze in a drain plug, makes for easy removal next time.

    I have a 2006 chevy colorado my auto trans, keeps giving me problems in first gear always slips... starter at 20,000 miles took it to the chevy dealer was told no codes. Took it back again at 25,000 miles same problem and was told again we cant find anything wrong with the truck. well now it's out of warranty and IT STILL IS DOING IT called gmc and they told me I had to pay to have the trans taking apart to find out what's wrong I told them this is there fault because it was not done right in the first place while it was under warrenty, why should I have to pay THATS ALL THEY COULD SORRY NO CODES NO PROBLEMS BULL.... Now I have 78,000 miles THEY JUST DON'T CARE I WILL NEVER BUY A GM MODEL AGAIN......THEY SUCK.

    Hello Foldem,
    I apologize that you are still having concerns with your vehicle. Do you currently have a case open if so what was the case number? Have you ever taken the vehicle to a different dealership for a second opinion? Thank you,

  • Along with a clogged cat, bad ABS brain and really crappy running condition, now the truck makes a horrendous noise backing up. A loud clacking sound like someone has a hose clamp around the driveshaft hitting the floor board (remember that trick? With tie wraps?) I believe it's the input bearing going out. Already had a complete new clutch kit which did nothing. Hunk of junk I tell 'ya. All this at 65K miles. Never buy one of these money pits!!!!!!!!!!!!!
  • I own a 2006 3.5L-2wd that I bought brand new & just experienced the same problem. The night before I was going from rev to drive & it made a loud shudder clunk. But it sounded like from the rear end. Then it acted like I wasnt getting proper torque/power. Gas peddle was even mushy & somewhat unresponsive w/no change in RPM(slippage). Then abt 2 miles down the road it all straightened out?? Now today I get in & have no 3rd & 4th but will move in 1st, 2nd, & rev. Have not taken it out on the road yet. Worried it wont make it back??

    What all did you find out & do to correct your prob?
  • Did you get a check engine light? When I had this problem it had a code relating to shift solenoid B bad. I have not had the problem since it happened the one time but since I was overdue on a tranny service I did that. Maybe I'm paranoid but I don't think the tranny is shifting quite right but don't know for sure. I found the ACDelco solenoids on Rockauto.com and theya re not expensive but have to drop the pan to replace. If I have further problems that's my next action. NOTE: they don't list the solenoids as A, B etc., they list them as 1st to 2nd, 2nd to 3rd and so on go up then in reverse for down shift. When I called RockAuto they got ACDelco on the phone and i believe 5 in total are required if you replace all of them. Let me know the outcome....GOOD LUCK
  • I have a 2004 colorado i bought when they first came out recently hitting over 100k miles i noticed high rpms on the beltway and when i got home and went to park i had to give it alot of gas to get it to to move in reverse and it makes a weird noise i checked the fluid it was very low so i added more it stopped the high rpm problem but reverse is still doing the same thing help!

    My 2009 5 cyl crew cab Canyon has issues around 50 mph. When my foot is on the pedal with moderate force the trans keeps flipping between gears. If I back off the pedal or apply more force it stops. It seems to happen when I try to move a few mph faster from around 45 to 50 mph. If I apply more force to create a higher increase in mph it's fine. It's annoying to have to play with it even for the few moments it occurs. Anyone have any idea what causes this to occur? The truck has around 24k on it.

    "toohip" at 45 MPH or so, you're right around the point at where the torque converter locks up, putting you into overdrive. However, this "lock up" also depends on coolant temp, load, and throttle posision. If you're just on the edge of any of those parameters, the tranny has a tendency to "hunt" a bit, until the vehicle load/speed has stabilized.

    toohip,

    Have you taken your vehicle into your local GM dealership to be diagnosed? Please keep me posted on any information.

    Thank you,
