2005 Chevrolet Colorado Transmission and drivetrain Problems

“2005 Chevrolet Colorado i4 engine 5 speed manual transmission. Cannot engage reverse 70% of the time. I understand others have experienced the problem but Chevrolet has a TSB (#611) saying condition is normal. I believe this is a safety issue if reverse cannot be engaged. Problem has not been resolved.”

“There are 2 major safety problems associated with my manual transmission. 1. When cold, it is pretty much impossible to downshift into 1st or 2nd gear unless I come to almost a complete stop. What this means is I cannot get into these gears to speed up quickly if I need to avoid an accident. Chevrolet said this is normal! 2. It is difficult to shift into reverse some times. Chevrolet even has a bulletin, but they said this is normal as well! What if I need to go in reverse real quick to avoid an accident or a train?”

“Purchased new 2005 Colorado lscrew4x4 in november 2005. I have noticed lately that when backing up or driving forward at an angle over a curb or on a slight grade heard a knocking/popping sound from the rear axle. If you take the side of the bed and force it side to side you can hear this knocking/popping soun severly. I called community cherovelt in burbank, and was told by service department this was normal sound. It does not make sense that this severe of a sound is normal. I called another dealer, and was told to bring it in to check it. I have yet to do this.”

“During normal driving my truck will shift into 4wd-high. I cannot determine if it occurs at highway speeds or low speeds (<30 MPH), I only notice it when I go to turn. The occurance is intermitten since I bought the truck new in september 2005. It has almost cause me to have a head-on collision with an oncoming car and a building because the turning radius is affected when it shifts into 4 wd. Since the truck has push butten control to change to 4 wd, for several months I thought I bumped or pushed the button by accident, but that is not the case. …”

“On or around march 21, I was driving my 05 Colorado to work. When I almost arrived I noticed that my truck was driving very forceful and jumpy. When I got back into my truck, it was having trouble starting, but eventually did. That night I was driving home and when I got about 2 miles from my house a message came up on my dashboard that said power failure and it stalled out. The next day, it started ok enough for me to take it to a nearby chevy dealership. They told me that it was the solenoid valve and the camshaft position actuator was replaced. …”
