Transmission slipping, rough shifting - 2005 Chevy Impala
I own a 2005 Chevy Impala LS with 3.4L engine with automatic transmission. This vehicle has had numerous problems since I bought it from a private party. The most serious problems are turn stalk failure resulting in headlights abruptly shutting off unless high beams are on, transmissions shifting problems and failure of the rack and pinion steering. All of these problems were after the warranty had expired. Initially, the turn stalk failure was intermittent; then, all the time. I replaced the turn stalk at my expense. The mechanic at the private auto shop said the GM mechanic said it was a constant problem and the GM mechanics replace them almost every day. Before that I replaced the rack and pinion assembly at my expense. Now, the transmission is slipping and rough shifting which is either a pressure control solenoid or solenoid problems internal to the transmission. GM suggests replacement of the transmission which costs $3500. But, if its a GM transmission; the problem will begin again after 50k-90k miles. The problem is with the GM solenoids which are defective. GM is fully aware of the problem. I suggest that all Impala owners from 2000-2013 file a complaint with NHTSA (National Highway Transportation Safety Administration) immediately. This is a safety issue since some vehicles have abruptly lost acceleration in traffic. Additionally, contact your Senator or Congressperson and describe the problem. This IS and election year and a wonderful issue for elected officials to talk about. Rebuilt transmissions are available from aftermarket auto parts companies. Transmission shops will also rebuild the transmission using parts that are not defective but have been updated to resolve the GM original equipment failures. Rebuilt transmissions range from $1500 to $2500. GM should recall the transmission and rebuild them with better parts than the original parts.
