A design flaw has led to the original ECU in RAV4’s 2001-2003 malfunctioning sooner or later, regardless of service history or mileage. This is a hardware and not a software problem so re-programming will just hide and not solve the issue, potentially leading to bigger problems in time.

The problem shows itself by the gearbox on your RAV4 knocking or juttering, harsh gear changing, losing 2nd and 3rd gears or power or a clinking when going into reverse.

You may also get false diagnostic codes of P0750, P0753, P0758 and/or P1760 on you Toyota RAV4.
