2002 Toyota RAV4 transmission problems

I recently had to replace the transmission on my car because the car was shifting erratically. After the transmission was replaced I still had the problem and was told that there was a technical bulletin from toyota tc002-6 which said that a faulty engine control module (ECM) will cause harsh shifting. Toyota did not communicate this problem to me back in march 2006. If toyota would have communicated this defect, I could have had the ECM checked and probably saved my transmission.

Tl* the contact owns a 2002 toyota rav4. While driving between 45-50 MPH the transmission exhibited gear shifting failure. The vehicle was taken to an authorized dealer for inspection. The technician concluded that the transmission had slipped gears,therefore the vehicle was repaired. After the repair the failure resurfaced. The vehicle was taken back to the dealer and repaired. However none of the repairs have remedied the failures. The failure mileage was 82,000. The current mileage was 83,000.
