 The engine slips and then slams into gear on soft shifts between 0 and 20 miles per hour. not on every sot shift but it happens often enough as to where i felt the problem needed to be heard and hopefully addressed.

 I bought a new 2006 monte carlo in july 2006. since new i've had issues with the car accelerating when stopped. also, traveling at steady speeds the rpms fluxuate. now when you use the cruise control, as the car goes down a grade it pulsates and the rpms fluxuate then clears. gm and dealer says it is normal. i've owned a lot of gm cars and this is not normal. had the intermediate steering shaft,,rack and pinion assembly, power steering hose all replaced under warranty. had to fight with gm to get the rack replaced. bolt broke on the rear brake cable, dealer said i hit something but not a scratch on the bottom of car and hanger sits up in the frame area. *tr

 I have a 2006 chevy monte carlo ss with the ls4 v8 engine coupled to the 4t65hd transmission. the transmission ai starting to act up, missing shifts and slipping every once in a while. i understand that there are many others experiencing the same thing. my car only has 45000 miles on it and it has not been abused.

 The transmission in the vehicle is know for catastrophic failure in several internal parts. gm knowingly put a transmission that was rated for a v6 in a car that produces more horsepower and torque than the transmission is rated to use. the torque converter, clutch pack, and input shaft are all known to fail in these transmissions. i am currently experiencing several symptoms that are linked to these parts failures. i am going to repair the transmission very soon due to the weak points that gm failed to recognize early on in the development phases of the vehicle. the transmission often slips and gives hard shifts under normal driving conditions.

 2006 monte carlo ss - 4t65e-hd transmission failure... sliipping... shuddering/shaking the whole front end when shifting... lunges/slams into gear... had to get transmission replaced! there are over 100 other people i know in online car forums with the same problem with this transmission in their monte carlos, impalas, and gxp's. starting anywhere from 20,000 miles to 90,000 miles... and some are on their 2nd or 3rd replacement transmission already!!

 I bought my 2006 monte carlo, it has less than 23,000 miles on it. i have experienced continued harsh shifting/slippage of the transmission since i purchased it. i have had it in the local chevy dealership a few different times and they are not able to diagnose the problem. they say they can't fix it if it doesn't shift hard for them when they have it. just yesterday i had to have it towed to the chevy dealership because it blew a power steering hose. *tr

 Tl*the contact owns a 2006 chevrolet monte carlo super sport. upon purchasing the vehicle in july of 2006, the contact noticed that the vehicle would lunge forward or backwards with force. the vehicle was taken to the dealer and they stated that there were no failures; however, the failure continued to persist. he returned to the dealer and they stated that the torque converter was defective, which caused the motor mount, transmission, and steering column to fail. the mechanic repaired the transmission, but none of the other components. the manufacturer stated that their engineers would receive the information from the dealer in order to find out the cause of the failure. the current mileage was 35,000 and failure mileage was 7.
