Automatic Transmission problems of the 2005 Toyota Avalon

Our 2005 Toyota Avalon was serviced for safety recall on 3/1/10 and gas pedal feel became more sensitive immediately afterwards. On 3/2/10 while driving in rain the abs system activated several times during normal application of the brakes. This was alarming and very disconcerting. Subsequent driving later this week did not effect a repeat of the abs concerns. However, there is an occasional slight surge in speed which seems to relate to the transmission shift points which did happen before the recall service.

My 2005 Toyota Avalon with the 2gr-fe v6 engine revs high, even when it's warmed up. In traffic, many times it revs high and lunges forward. Several times I braked hard to avoid read ending the car in front of me. This has been ongoing since I bought the car in 2005 as I am the original owner. I've taken it in to Toyota service and the mechanics found nothing. Once I showed them a technical service bulletin from Toyota which stated the exhaust manifold, oxygen sensors needed replacement and the ecm needed to be reprogrammed. It worked for a year (2007) then back to the same problem, high revving of the engine, hard shifting and lunging forward or reverse. The latest incident was today, 12/7/09 where I almost hit a pedestrian since the car revved high and lunged into the crosswalk. I had to press the brakes hard to prevent hitting the pedestrian.

I was parking my car at work. I pulled into the parking space and backed up slightly to straighten my car. When I put the car into drive to pull forward again , the car raced forward with engine revving strongly. I could not stop the car with the brake. The car crashed and pushed through a thick brick wall. The airbags did not deploy. The car would only stop after I pushed the engine shutoff button. The gearshift was hard to move after the incident.

Transmission delay upon exhilaration that put me in a poison of accident, since the car doesn't react or respond on time.

I have filed a complaint with Toyota regarding the hesitation and erratic shifting of our 2005 Avalon. I was told that it was due to the way the computer controls the new 5 speed transmission in conjunction with their electronic fuel injection control. In researching this problem,I have read where many other Avalon owners have also experienced this. On sun. ,03/12/06,I had just exited route 80 eastbound (exit 27) in n. J. And proceeded to merge with traffic on route 206 and had to immediately make a left turn. As I pressed on accelerator,the vehicle simply did not respond (hesitation) and, when it did engage after a second or two,lunged forward. This startled all in the car (myself and 2 passengers) and was a very unsafe occurrence as traffic was heavy and moving fast. The vehicle has approx. 7500 miles on it and will be a year old in June,2006. I have an appointment for service with my dealership on tues. ,03/21. They are to go over the car and check to see if there are any tech. Service bulletins. I have been checking on existence of TSB since shortly after buying the vehicle. I am not optimistic. This is a serious problem and Toyota should be doing something about it! thank you.

Since purchasing in Dec. , 2005, transmission hesitates when proceeding from idle at slow speeds and sometimes between gears at highway speed when trying to accelerate. Have nearly been rear-ended innumerable times. Original several complaints to dealer resulted in info that "no TSB has been issued to fix that". This last time I complained, I was told that it was natural feature of drive-by-wire, that no TSB had been issued which fixed it, and that Toyota was not going to do anything about this known problem.

The contact owns a 2005 Toyota Avalon. While driving at approximately 4 mph, the vehicle began to independently change gears and jerk violently. The contact took the vehicle to the dealer for unrelated maintenance and advised the dealer of the failure. The vehicle was not diagnosed or repaired for the failure. The failure persisted and became progressively worse. He contacted the dealer and secured an appointment for diagnostic testing and possible repairs. The VIN was not available. The failure mileage was 600 and the current mileage was 21,500.

I just purchased 2005 Toyota Avalon limited. I experience terrible transmission hesitation/slippage. It is getting dangerous when I have to enter highway ramp because of transmission hesitation. When I coast at low speed, for example, I notice a red traffic light ahead and take my foot off the gas, the car then continues forward as if in gear and after a period of time it feels as if the transmission shifts to neutral, the rpms drop to below 1,000. Then the traffic light changes when my speed is about 5 - 10 mph and I slowly depress the accelerator. The engine rpms increase about 300 - 500 rpms but there is no acceleration. Then the transmission gets the message and we start to accelerate.
