Hi all - anyone with a Rav4 from 2001-2003 ever experienced problems with gears changing at random? This is a problem with the computer (ECU or ECM) that is sending the wrong message to the transmission and it changes into the wrong gear without warning. This is known as 'harsh shift' problem: http://www.rav4repair.com/documents/TSB0156.pdf If you have this problem, or had it, it is really important that you report it to the Department of Infrastructure and Regional Development ASAP: https://www.infrastructure.gov.au/vehicles/complaints_recalls/form_submission.aspx They investigate products that have safety issues and will inform the ACCC if a recall is necessary. A recall will not happen unless there are reports of the product failure and safety concerns through the Department of Infrastructure. I am looking at the possibility of starting a class action for a recall because this is a factory fault that is putting Rav4 drivers in danger. It is well documented and well understood by Toyota. These are the most common symptoms: Erratic Shifting.Transmission slips in any gear, but mostly from second to third gear.Starting in 3rd gear and shifting erratically or not shifting at all.Hesitation when engaging in any of the gears.Rattling noise coming from the front area when the engine is running.The feeling of applying the brakes by it self in occasions.False solenoid codes; P0750, P0753, P0755, P0758 and/or P1760.The codes above not always show (DTC codes). Sometimes it fails with no codes at all or no check engine light.Engages hard in reverse with a "bump" or takes time to engage.Symptoms are intermittent. Sometimes symptoms only show up when warm or when cold and sometimes symptoms do not show at all.One day it runs OK. All the symptoms magically disappear, but the next day, all or some of those symptoms are back.In many cases, fuel economy or gas mileage is lower than normal.This is a safety concern as the car can shift into a low gear without warning while you are driving at high speed or in heavy traffic. Because it is a gear change, break lights don't warn cars behind you that you are suddenly stopping or slowing down, putting you in a dangerous situation. I have also been stuck trying to cross traffic at an intersection and it has dropped into top gear and I cannot move across the intersection and out of the traffic. I have been in touch with the ACCC who are looking into the matter as there was a recall by Toyota in USA: http://www.rav4repair.com/documents/warranty.pdf If anyone is experiencing these problems or has had this fixed and you are interested in putting pressure on Toyota for a recall in Australia, please contact me. If this happens, the costs of your repairs could be reimbursed. Toyota_warranty policy bulletin.pdf
