2007 Chevrolet Silverado Transmission and drivetrain Problems

“While merging onto the express way I had a major loss of power and a slight shake in my Silverado. Multiple engine lights came on (stability track, traction control, and blinking engine light). On my way to the nearest GM dealer, at every stop light the truck lacked power to get going when the peddle was pushed, then it would kick in and screech the tires. After leaving the truck at the dealer, I receive phone call from the dealer the following day stating that the lifter (afm lifter) had malfunctioned and was stuck. …”

“I have marked power train and electrical since both are involved. I was driving home from work when my truck message center indicated (reduced engine power) . This is dangerous when my vehicle is impeded from accelerating and slowing down to no more then 20 - 25 miles per hour. Since I could of interfered with the traffic and cause an accident or bodily injury to others. A recall should be made since I have noticed a lot of other vehicles have the same scenario.”

“On 10/18/2010 returning home from vacation, my right front wheel assembly suffered severe internal failure. The dealer in south carolina repaired my vehicle, and covered the expense of the replacement part and labor under the powertrain warranty.

“Thump after coming to a stop. After about 24,000 miles. I started feeling a light thump from the rear, as if someone bumped me from behind.

This seem to work for the next several weeks. Then the thump returned lightly at 1st & gradually worsened to a major thump. I returned it to the dealer & this second repair was that the lubed the rear-end & replaced the yoke on the driveshaft. …”

“I am getting a noticeable vibration in the drive train at about 45 MPH. It finally subsides at around 55 MPH. I have had the oil level checked in the transmission and the rear end oil checked. All is ok in those areas. Contacted a local Chevrolet dealer and explained the situation on the phone and I was told that is was normal for that make, model and drive train. Also had the underside of the vehicle checked to see if there was anything loose that might cause the problem especially the exhaust system and all is ok. Never had this problem before. Just started. Chevrolet won't bother with it.”
