Replying to: tedescm1 (Nov 06, 2006 7:22 am) we purchased it. Now it has 40k and there really are no transmission problems. A slight little whirling noise between 20 and 30 mph. Been that way since day one. Been driving the wheels off the thing and so far so good. First thing I did was dump all the oil, trans, engine etc. and put synthetic oil in everything. Went to Salt Lake City Utah from San Fran area, got 34.8 mpg with the cruise control on. Average speed 70 to 80. Works for me. How has yours been working out?

Replying to: oldfart2 (Feb 13, 2007 10:49 pm) My friend owns the car and the lease is up in June. The car has 15K miles on it and i am told that he has never had any trans hesitation so i think it's ok. He's an old friend and I trust him...

My ES330 uses the previous generation of transmission and computer. It sometimes hesitates on acceleration but I have never felt in danger because of it. After careful tests I have determined that on my car there is hesitation only if I gently press the gas pedal. This is fine because it saves gas. When I stab the pedal, the car takes off briskly. The hesitation problem for the newest transmission and software combination may also be related to how quickly and how far you press the pedal. The computer can easily determine how fast you are moving the pedal, which makes this different from what we are used to with a non-computerized transmission. I think that this is a side effect of an algorithm in the engine computer designed to get better mileage and emissions ratings in the standard tests. It has been an issue with several Toyota models for several years. For me, the 330 has turned out to be a great car. |

Replying to: tedescm1 (Mar 05, 2007 5:43 am) We were driving on a single lane road and I got tired of driving behind this old beat-up pickup truck at low speeds. I floored the gas pedal and immediately the rpm went up from 1600 to about 5000 rpm, I overtook the vehicle and as I eased off the gas pedal, the vehicle refused to drop rpms and speed. The vehicle behaved as if I was driving in 1st gear and stuck in it. Also, the sound from the transmission was unbearable. I wanted to slow down and kept on shifting to 4, 3, 2, while pushing down on break pedal with my foot, anything that would switch off the vehicle but to no avail. I then shifted to Neutral and that did not help, either. The vehicle was still going fast. Luckily, there were no cars on the road in front of me. In my last desperate attempt, I simply took the ignition key off. The vehicle finally came to a stop. I then caught my breath, put the key back into ignition and started the car. It was Ok, finally. I really did not feel I had to take the car to my dealer as I was afraid they would laugh at me. I no longer try to floor the gas pedal anytime I drive this car.

Replying to: gavrik (Jul 14, 2007 11:24 pm) I presume when you put the vehicle in N or Neutral, the vehicle speed would have continued to decline, specially if you put on the brakes... However, perhaps the engine reving would not go down for you. That MUST BE diagnosed by your dealership. Further, you should report your experience with the NHTSA site. Never though should you turn your ignition off. Not only can you end up locking your wheel, you'll loose power to the stearing and braking systems. Again, when you put the vehicle in N (Neutral), that should have de-coupled the engine from the transmission / wheels, and you should have been able to slow (although with engine perhaps racing). If that's not the case, then you have a totally different problem.
